now our nation comes together ten year after those attack to remember the heartache and horror and to honor the heroism and resilience of american spirit. this is a special edition of "good morning america." 9/11 america remembers. and the people of abc news once again right there, connecting with americans on this emotional, historic day. just as we were on this morning ten years ago. we're live from ground zero, the pentagon and shanksville, pennsylvania. now reporting, diane sawyer and george stephanopoulos. and good morning to you, i'm diane sawyer at abc news headquarters in new york with george stephanopoulos as we join to remember where we were, what we saw and the strength we found all of us together on september 11th ten years ago. t began with a blue sky, sunny morning and then game the darkest. 2,977 lost an attack that tested our nation in so many way, revealing weaknesses and strengths we haven't seen before. now we go to ground zero. it's become such a symbol of that resilience and rebirth of the united states. >> ten years later, another sky-blue day. i keep thinking the youngest of those who died, 2 1/2 years ol. you will be with us in a few moments as 20,000 family members are present at ground door row and expected to walk up for the first t me to those reflecting pools and find the names of those they love, etched around the edges. that ten years have brought us new terror threats, including the latest, george, bring us up to death. >> that's right. we have terror reports, intelligence reports that at least three people may have entered the united states, with the intent to launch a car bomb against new york or washington. p there's no reason to lessen the alert status. we honor those who lost their lives ten years ago and take the measure how fare've come. how america came back to restore and rebuild the worst attacks in history. our entire abc news is with us here in the studio in those places that were hit ten years ago on 9/11 we are taking us through the 110 year of that took us through history. there will be six occasions today when we pause together. the first two will be when the first two planes hitithe towers, one hit the pentagon next and then another outside shanksville, that's the second two and then pausing again, when the first tower fell, and then the other tower fell. >> and we're going to follow it all over the clock in the lower left-hand corner of the screen, mashing those 102 minutes as they play out on that morning ten years ago. that is the time from when the first tower was hit untnt the last tower fell. >> as we said, the families are gathering at the site of the member report yal,l, where the lives were lost, and no place has come to symbolize america's resilience, more the world trade center we building. it is, as i heard someone say, not just a scar. it is also a say credit place, and both can exist at once, and also t t power of survival, so evident there. but, now, we want to bring in our team and someone who has been your friend for so long. our friend for so long, and now, officially a member of the abc news family, and we are so glad to have katie couric here. you were in another studio that morning, watching when i was in the "good morning america" studio. >> that's right. >> and here we are together remembering. >> you know, it was such a terrifying day, and so emotional, even to revisit that day, and to listen to the two of you describe what happened. and i rewatched our coverage last night. and it was as stunning and shocking as it was ten years ago. and in fact, it was even more horrifying in hindsight, now we know what was going on in those towers, what was going on in the pentagon and aboard flight 93, united flight 93 that crashed into shanksville. today, i'll be reuniting with some of the families. i'm happy to report that many have developed a new normal and they're well into the healing process. i think it will be reassuring for everyone to see some of these family members. >> katie talked about life inside those towers. you talked to some survivors from those minute, ter tying minutes in the towers. >> really terrifying. resilience from moment one from the survivors, didn't know how to go up and down. and split second decisions made the difference between life add death. diane was talking g out be on that morning. the cruel moment, a lot of people got phone calls. i remember receiving a phone call, you got to turn on the the tv. we turned on to watch the second plane come into frame. when you see the blue sky, it takes us back to that moment. these survivors give us true hope how they lived their lives. >> christiane amanpour, you saw it through the eyes of the rest of the world. >> that's right. the whole world was river vetted. i was overseas. one thing, was the adversaries and friends of the united states, declaration of solidarity and stding, shoulder to shoulder, the famous french headline which said in french, we are all americans today, and nato invoking its charter, an attack on one is an attack on all. collective self-defense. it was an amazing moment of solidarity. we'll talk how it's changed and has come full circle. >> we also focused on families. this is the first time for many families to visit this memorial down in ground zero. it's called reflecting absence. recognizing the endurance of those who survived and courage of those who risked their lives to save others. my "good morning america" coanchor, robin roberts is at the memorial today. i can only imagine what the feel something down there. >> especially under such a blue sky, good morning, george. it's going to be an emotional day. the families were seeing the memoriri, they were sent letters where to find the loved ones names around the waterfall. president obama and mrs. obama just arrived here as well. families know they are not standing alone. they knew that yesterday as well. here in lower manhattan, a lot of local residents, they joined hands, and that human chain that they formed, was just yet another symbol of the hope and resilience that we feel here in the midst of such tragedy that happened ten years ago, george and diane. >> robin, i know the construction workers are doing the same thing. they are building not just a memorial, they are building a cathedral to hope. robin, i want to ask you, because we called it ground zweer row all these year, but i'm told the mayor has said, it's time to move on. call it something else. >> he has, diane. mayor bloomberg this week, a lot of families stand with them saying, it is time to move on and not refer to it as ground zero, but as the world trade center and september 11th national memorial and museum. the museum will be opening next september. everyone, a lot of families do not want to forget. yes, they want to remember but move forward at the same time, diane. >> robin, thanks. we look back at who we were then. small things, of course, have changed in our every day lives. not so small for the facebook users, no facebook then. victims have to rely on list serves to try to mobilize on september 10th. 24 hours of before the attack. 1% of americans 24 hours before said terrorism was even one of the nation's top problems in that age of incense. >> now it's something americans say they think about all of the time. it's something we do think about. it has been such a wounding decade in so many ways. we've also seen that resilience we've talked about. we had bill weir go back and take a look at how we've changed. it's an amazing story. >> oh, my god! >> reporter: many will ask, where were you on that severe clear morning. >> huge explosion, raining debris on all of us. >> better get out of the way. >> reporter: but here's a deeper question. >> you okay, officer? >> reporter: who were you? how did you change? is that the first time you ever stood in line to give blood or buy a flag? how long did you cheer for every passing fire truck, or flinch at the sight of a muslim scarf? did you drive cross country to help dig through the pile? and were those tears of fear or pride when your kid rushed down to enlist? and who are we now? now that the smoke has cleared? and the rubbles gone? now that the shattered stores are back in business and the president's bull horn is in a museum? and the people who knocked these buildings down will hear all of us. >> reporter: what is america after this decade of freedom fries and anthrax square, aftft tsa, ied, tei, became our new alphabet. republicans and democrats, standing together, singing together. was a blessed novelty after the florida recounts and seems even quainter after today's political standards, but arguments are the heart beat of democracy, not since the civil war have we had more to argue about. >> stop the madness. >> reporter: consider how the line between liberty and security has shoveve and shifte. . ten years ago, almost half of the country called terrorism america's most important problem. today that fear is swallowed by unemployment lines, housing prices and the next monitor storm. we can see that the always orange alert system is now history but what we canan see are the alarming numbers keeping watch from the shadows. 800,000 americans, about the population of south dakota now have a top secret security clearance. we can count the decade's toll and missing limbs from roadside bombs, harder to measure the number of families wrestling with the hidden pain of post traumatic stress. the american death toll in iraq and afghanistan is now twice as high as the number murdered on 9/11. but since less than 1% of the nation put their boots on the ground, it's all too easy to forget we've been at war longer than any time in our history. abu ghraib is long closed. guantanamo bay is still open, but in the end, the arab spring, have nothing to do with american foreign policy. so much changes in the decade. heroes of that day, rise and fade. >> conducted an operation that kaled osama bin laden. >> reporter: villains are hunted and killed and there's spontaneous joy at the scene of the crime. ♪ >> reporter: after all of those funerals, the waiting list for the new york and fire and police departments longer than ever. a new generation of the bravest, yearning to rush into the next man-made hell. there's the resiliency of a widow who managed to build a happy life after love lost, and the unity of a soldier's homecoming. that, is still who we are. that is america. "nightline" anchor bill weir on a decade passed with history and heroism. as bill was giving us that piece, president obama and president bush arriving down at ground zero, at the ground zero memorial. >> president bush, of course, in office saying, the first plane came in, he knew we were under attack. then he knew we were at war. president obama a en a 40-year-old illinois state senator. a long time ago in his life, and the life of this country. but, katie and i were talking earlier about what it was to watch this on the air, to see it unfolding. of course, all of us did that together, too, as people did call and say, are you watching? are you watching? we want to remind everyone what it was to see it as it unfolded. the incredulity as it unfolded. "good morning america" imnice to see all of you, i'm charles gibson. >> take a look at the highlights, new york city, beautiful day here. 83 -- >> we want to tell you what we know. we just got a report in that there's been some sort of explosion at the world trade center, in new york city. one report said, and we can't confirm any of this, that a plane may have hit one of the two towers at the world trade center. again, you're seeing the live pictures here. >> then there was a loud explosion, and immediately lots of screaming out on the street. >> move it, move it. come on. >> oh, no! >> world financial center, we heard a big bang, then we saw smoke coming out. >> abc's done daler, give me some description what you can see now? >> it appears there's more and more fire and smoke enveloping the very top of the building. as fire crews descending on this area, it -- it does not appear that there's any kind of an effort up there yet. remember -- oh, my god! >> that looks like a second plane -- >> that just exploded. >> we just saw another plane coming in from the side. this looks like it is some sort of a concerted effort to attack the world trade sent theory is under way. oh, this is terrifying. awful. >> to watch powerless is a horror. >> abc's peter jennings is at the anchor desk uptown and is now in position. peter, you are looking at the exact same pictures? >> we are, we will be watching this for much of the y. there's chaos in new york right now. >> let's go to claire shipman on the phone. >> that's what we're looking at right now. we know a gigantic plume of smoke coming from the executive office building. >> let me interrupt you, we have fire at the pentagon. we believe a aircraft scratched into the courtyard itself, or into that side of the building. you can hear it, let's listen. >> let's go, move! move! >> world trade center, you can see the fireman assembled here, of the police officers, fbi agents. you can see the two towers, a huge explosion now raining debris on all of us. >> better get out of the way! >> the second building that was hit by the plane just completely collapsed. the entire building just collapsed. it folded down on itself and it is not there anymore. >> the whole side has collapsed? >> the whole building has collapsed. >> the building has collapsed? >> the building has collapsed. >> let's go! let's go! >> we're talking about massive casualties at the moment, and we have -- and i'm just going to add to the chaos and trauma of the day, by saying that a large plane, has now crashed, about 10:00, in the last 15 minutes, 80 miles southeast of pittsburgh. >> they seem to have a problem at the north tower. >> let's look at the north tower, quickly, quickly coming down. >> oh, my god. both trade tower, where thousands of people work, on this day, tuesday, have now been attacked, and destroyed. >> get out of here! >> i checked in with my children, and -- who are deeply stressed, as i think young people are across the united states, and, if you're a parent, you got a kid, in some other part of the country. call them up. >> you saw it inn peter's eyes, you heard it in his voice, everyone trying to come to grips with the chaos that was spreading across the country that morning and dealing with it by reaching out. >> yes, we were somehow still in the midst of this unfolding horror, this cascade of horror, an army of generosity out around the country, as people immediately knew that this was the time to link arms and rally together. >> and rush down to ground zero where so much help was need thad day. we want to go back there, robin roberts is there. memorial going to be seen for the first time by the families called reflecting absence. robin, it is striking h h mucuc creativity and thoughtfulness has gone into producing this emmemorial. >> and it tookok lot of time, george, for that. i have to tell you, i saw it up close myself and you can see it right here. president obama and mrs. obama mr. r were there as george bush and mrs. bush were there, and their daughters were there. you see the emotion as they place their hans on the names. a lot of thought went into that, how to place and where to place, colleagues, co-workers, friend, families, officials said they honored thousands of family request. abby goldman was working on the north tower when it was hit by flight 11. abby's father was in that flight and she wanted her name placed alongside her best friend. that's one aspect of thought that went into rebuilding and remembering what happened here. a decade in the making. it's called the most complicated construction site in the world. harnessing together architectural design, a sense of loss and rebirth for the country and the victim's families. what are you hoping that they are going to experience, and feel, seeing the memorial? >> the purpose of the mememial is to give families a place to grieve, to tell the story, so that we don't forget that our grew dfreedoms are fragile. >> housed inside 16 acres of land, a museum set to open next september and two memorial pools engraved with 2,983 names of those lives loss. >> the truth of the matter, ten years to do what we've done i think is very commendable. >> reporter: the progress made since i toured the site last year with new york city mayor michael bloomberg and joseph daniel, president of the 9/11 memorial and museum is clear, trees now flourish. >> i cannot get over the changes in a year. here the survivor's tree that survived. >> the tree that survived, 95% destroyed and now flow eshing among 225 other trees. >> reporter: the two pools now flowing. >> the pools done. marking the footprint of where the north tower was. all of these people that were in the buildings that day are around this pool. to have the name, even in the rain it's almost like tears among the names themselves. it feels like we marked this sacred spot and took a lot of work, for the families and public, it's worth it. >> rain that day, but a beautiful blue sky for the families. they will get a chance, for the first time torks see it today. it will be open to the public beginning tomorrow, at 10:00 a.m. 10:00 to 8:00 p.m. they are only allowed to allow 1500 people at this point. you have to go online to reserve a ticket. you have to remember, this is still an active construction site. for the next year, year and a half, they have to limit the number of people that will have to come here and be able to see for themselves this spectacular memorial. diane, george. >> robin, the details of the memorial, just fascinating. when people go up to touch the names, it will always be at a moderate temperature, it will be cooled in the summer, heated in the winner. >> they keep it temperature controlled so it's never too hot or cold to the touch. she talked of the survivor tree. a symbol of so much. it was charged, it was broken. only 8 feet tall. it's now 30 feet tall. we remember what life affirmed. we are going to take a break, because we want to be sure, when we come back, that you are with us, as the new york city fire department, the new york city police department and the port authority, send the bagpipes into the memorial site this morning. we'll be back after a break. 1,183 fragments of steel from the trade center have been distributed to memorial sites and all 50 states and around the world. ♪ these sweehoney clustery things have fiber?

[ male announcer ] save lids to save lives with yoplait. available at your local safeway store and, welcome back, we are glad you are ginning us this sunday morning. and we want to show you again, live, ground zero, the memorial site, a morning to remember the fallen, to celebrate the resilience of a nation, as presididt obama said, chaos had come to our doorstep, but on this morning, ten years later, it is replaced, as you can see, by calm. and our abc news team is standing by at the site as well. >> that's right. we have chris cuomo down in ground zero. he's been following for ten year the heroes of 9/11, the first responders of the fire department, of the police department of new york city, he joins us now. >> good morning, george. such a powerful point was made to me. we know of the 343 fires. 37 police officers, 37 port authority officers and countless others here waging battle that day against catastrophe, and yet mfrn's battle is about perspective. so many more made it out. you have to look at it through the lens of how many were saved. 9/11 was the largest human recovery operation in historor thousands and thousands were save thad day. that is the legacy moving forward. we are standing in one world trade center. it is back. this tower will be taller than either of the twin towers, 1776 feet. the number obviously relevant to the rebirth of freedom and that is a message that so many of the victims families and first responder whose fought. construction workers who cut away to save, and now rebuild this site, want us to remember. there was recovery that day. there has been rebuilding since. the world "resilience" means that you snapped back to what you were before. that's not the case. we'll never be the same. no one ever will be. but we will be better. we'll be more taller, we'll be more beautiful. we'll be more unified. that's what they're hoping the message is for today, george. >> and the message president obama will be making when he commend rates the day. not only ground zero but in shanksville and washington, d.c. jake tapper is with the president in washington, d.c. this mornrng. >> good morning, that's right. this is the second time this year president obama has been to the site. he has been here earlier in may after the successful mission to kill osama bin laden. he did not speak when he came here in may. today, he will speak. we're told he will read from psalm 46, god is my refuge and strength. later on this evening, back in washington, d.c., he'll deliver personal remarks. president obama just took a tour of the pool at the former site, the footprint of the north tower. he and first lady, michelle obama, along with former president george w. bush and former first lady, laura bush walk add round and looked at the napes. president obama was here, he was very touched back in may, he was very touched of the story of peyton wall, a groung girl who was just an infant, just a toddler at the time when her father called home in new jersey to tell them thatt he was -- th building was under attack, and he would probably not be returning home. this is obviously been an event, that shaped his political career, as diane mentioned ten years ago, an obscure illinois state senator, but so many is e issues that came to the forefront because of 9/11, the war in rock. national security, national unity,ish thus brought president obama to the forefront. >> i was talking, you saw the bell, the image of the bell. that gives us an opportunity to talk about the ceremony seen today. each moment of silence, six moments of silence for each moment of impact. a bell will ring, there will be readings. over the course of the morning, family members as they have done each year, will read the names of those lost on that day. >> that's right. and listening to chris talk, as he indicated, the family members tell us a lot about what it is to gain strength, and to move forward, 17 children of firefighters, have become firefighters. the first fighters lost that day. two the children to police officers lost that day have become police officers, and so everyone, again, saying that this is something that goes forward. this is the moment that we've taken stock, and look forward as we do. the ceremony, as you said, is about to begin. it will begin with bagpipers, but i want to bring in the team here. you have all been out talking to the people who will be there. and we heard jake talk about those who phoned in, those whose calm reminded us of strength under extraordinary moments of terror. i know you talked to a lot of survivors there. >> people who call into 911 from the twin totors. a chilling thing to remember is after the towers fell, we'll see that as the morning plays on that thehe11 phone call went silent.. people were so calm up to that point and there were no calls after that. what struck me was the image of president obama side by side with president bush. this was talk after osama bin laden was killed whether or not both would be at ground zero. they did not reunite at that moment. but of course we're seeing the bagpipers. as you mentioned, solidarity after 9/11,, we're seeing that this morning. >> the bagpipers and drummers, leading the flag from the memorial to the stage, and all of those who lost their brethren that morning have contributed to the bagpipers. let's listen as they proceed. >> there will be 60 pipers and drummers from the new york city police department, the fire department, the port authority as well. as they exit the stage they're going to play "gary owen" with is an irish quick step that began as a regimental song in the early '60s. the trtrition carries on today. >> we remember how the search and recovery effort went on, the bagpipers, we remember the escort, the end of those days, and the bagpipers, and their mournful sound to carry off those who were lost. >> so many lost in the fire department, 343 members of the new york fire department. they were the ones who went up those towers, when everyone else was coming down. >> yes. i remember when mayor rudolph giuliani said he was going to five funerals a day. >> i think it's important to note that this ceremony today, is going to be one of simplicity. family members and family members alone will recite the names. there will be no political speeches, no prayer, even. it's going to be strictly the recitation of the victim's names from all of the sites that were affected that day and the names, of course, of the victims of the pentagon and united flights 93 as well as those in the twin towers are on those pieces of stone that surround the fountain. >> mayor bloomberg took some heat for not including the members but he has held firm to that position. >> as president obama was moving some of the families by the reflecting pools, one of the victors was the director of the port authority. his widow is there today. she's been a fliering member of the 9/11 memorial. she said to me the other day, wouldn't it be fantastic if the legacy of this difficult ten year was a renewal of the incredible unity that brought this country together? wouldn't that be the most fitting, most wonderful legacy of all of the difficulty and tragedy and sadness we've all been through as a country. everybody feels that. >> she told me that she wishes that this day would be like september 12th, 2001. >> i want to go to robin, who is there on site, robin. >> we're going to see more family member this year, reading 167 pair, compared to 166 pairs in previous years. what make this difference again, you see the bagpipers, the memorial. of course, in previous year, we've marked this day, but never with the memorial. the families that i talked to this morning are so eager t t come in and see their loved ones' names around two reflecting pools. >> robin, from here t-seems so brilliant, but also remarkably silent. >> it really is, george. they're now about to take the stage. we've been here for a couple of hour, as the family members are streaming in wititthe posters that you see, very reflectful, very quiet. and we know what they are feeling. they know we mourn along with them today. >> as the bagpipers begin. members of the brooklyn youth chorus who will sing the national anthem. you saw president obama behind a glass shield, one more sign of the heightened security at ground zero today. >> unfold. ♪ o say, can you see by the dawn's early light ♪ ♪ what so proudly we hailed at the twilight's last gleaming? ♪ ♪ whose broad stripes and bright stars through

first moment of silence, a moment of silence, then a reading from president obama. >> on that morning, he was running in the primary election for mayor, tried to go in and give blood, but the line was too long for him to be able to donate that morning, doing what he can, and of course, he has been the driving force behind achieving this memorial, by this date, even giving, reportedly, $10 million to $15 million of his own money to make sure this day happened. he said, again, he does not want it to be ground zero any longer. he wants it to be a monument to building a better world. >> in so many ways, he became elected mayor because of the terrible events of this day. >> forward march. ten years have past since a perfect blue sky morning turned into the blackest of nights. since then, we've lived in sunshine and in shadow. and although we can never unsee what happened here, we can also see that children who lost their parents have grown into young adults, grandchildren have been born, and good works and public service have taken root to longer those we loved and lost. in all of the years that americans have looked to these ceremonies, we have shared both words and silences. the words of writers and poets have helped expression what is in our hearts, the silence has given us a chance to reflect and remember. and in remembrance of all of those who died in new york in 1993 and 2001, at the pentagon and in the fields near shanksville, pennsylvania, please join in observing our first moment of silence. god is our refuge and strength, a very present help in trouble. therefore, we will not fear, even though the earth be removed and though the mountains be carried into the midst of the sea, though its waters roar and be troubled, though the mountains shake with its swelling.

a person we lost, in new york, in washington and pennsylvania. and they each had a face, a story, a life cut short from under them. as we listen, let us recall the words of shakespeare. let us not measure our sorrow by their worth, for then it will have no end. >> gordon a.aamoth, jr. >> edelmiro, abad. >> marie rose abad. >> andrew anthony abatement vincent paul abatement. >> lawrence

first tower. we have to remember, it was 11,000 pounds of fuel, a seismic impact felt 250,000 mile as way. >> something we've never seen before. we heard president obama read from psalm 46, god is our refuge and strength. there will be no political speeches. katie, i know you spent time to e family of david berry who worked on the 89th floor. >> that's right. this morning we'll tell you of some of the faces and stories that mayor bloomberg mentioned. david barry was a financial analyst. heeding the warning over the loud speakers at the time to not leave his office when the seconn plane hit. now, paula, his wife is one of 1609 people who lost a ouse, a partner that day. his three boys were 5, 7 and 9 at the time, are among the 3,051 parents who lost children. paula has been intimately involved building the memorial. as she and her sons spent the last decade trying to rebuild their lives. >> where we used to live, we used to be able to see the world trade center. we d d a thing, i was on the phone, and he would turn off the light, on or off. i said off. i could see it. i could. >> none nile berry's first day, that light was extinguished. his father worked in the tower. >> i remember seeing heaves of black smoke on this beautiful day from manhattan. a disgusting black smoke. >> his mother, paula, said first three months after 9/11 were like triage, she poured her energy into her sons but soon decided she had to do something and be part of the mission to create a fitting memorial to the lives lost, including her husband. >> does it feel like ten year, a whole decece has passed? >> it feels con injure up the day and reach back. that feels like yesterday. >> paula was the only family member that served on the jury that selected the design at the memorial. >> here's yohusband's s me, dav shelby berry. >> i asked for david to be listed next to his co-worker, they were very close, they knew each other very well. >> one of the most painful aspects this loss, and there are so many painful aspect, is that he is not around to witness the kind of young men -- >> yes. >> his sons have become. >> i say that all of the time to them. that, to me, is what i carry. that's the hardest thing to carry, because i loved him so have. >> do you ever feel like somehow, some way, he knows? >> yes. >> you do? >> oh, yeah. no, no, no. he continues and remains my muse, my parenting muse. >> you know, for 40% of the victim, no remains were ever found, so, these family member, many of them, don't have a single item, tangible evidence that their loved one perished that day. not a broken watch, not a tattered driver's license, nothing. paula emphasized to me, in many ways, this site is really a cemetery, , final resting plac for these family members. that is why it is so very, very meaningful to many of them who are there today. >> it's taken so long for so many of them not to say, maybe, maybe there's some place with amnesia in new jersey, and maybe, maybe they'll come walking through the door, because so few of them actually got the evidence, the identification that allowed them to say, well, he was there. >> in an instant and that was it. >> david, so many of them did have the final moment, the final phone call come in. >> they called from the top of the towers, they saved those phone calls, people who said i'm okay. and wanted to put their families at ease. one of the things, as the names being heard is a reminder to all of us. that there were 93 different countries represented by the people lost on 9/11. one from the reasons that the christiane pointed out earlier, the world came together. this is the world's lost. >> today, there are memorial, there are ceremonies remembering this in many, many countries. so many people lost so many. japanese whole financial team. 67 british people lost. second most certify veer loss after the united states. afghanistan where 9/11 is well under way, they've raised the flag in southern afghanistan with the names of everybody who was lost. there are remembrances all over the world, because it did fundamentally change america's relationship with the world and vice versa. >> it's not just a ceremony, you told me you were at the warehouse where they took pieces of steel from the world trade center and sent them across the country? >> that's right. over the years they gathered pieces of twisted metal that have fallen. they call it artifacts, archive this, is not wreckage, this is living memorial. in the last year and a half many have been shipped out to people in the country and eight different countries that have their own 9/11 memorial. >> when down at ground zero,o, was struck how every single momento of that day is -- as we know, the survivor's staircase will be in the museum, the last column of steel will be there not just the survivor's tree. >> no doubt that place will be a site where more momentos are placed of the victims again. is robin roberts still with us down at ground zero? >> yes, i'm here. >> can you give a sense what it's like as the names have been rea read? >> i'm trying to keep my voice down as well as they're being read. everyone, aus said, george, it is so quiet, only time we heard choir sang "the national anthem" but other than that, people are still adriving bause of all of the check points, it's difficult for all of the family members to get here on time. everybody is being very respectful and listening to the names that are being read. as i said before, this he are so anxious to go inside and see the memorial that we've been talking about, to see it for themselves. >> we are approaching t t second moment of silence. as pointed out, there were 16 minutes between the first and second, which, of course, was life saving for many of those who were in the tower, many of them were able to evacuate in that period as united flight 175 made its way toward the second tower. 14,000 -- 1400 of them did start to evacuate, based on what they had seen in that first tower. and that survivor staircase, many of them were able to proceed down, was essential. >> it certainly was. many remained, though, because it wasn't yet clear that this was in fact an attack, a concerted attack on the united states or both towers of the world trade center. at first, everybody thinking, oh, my gosh, it's some kind of a horrible act. and of course the second flight did make that very clear. it was united flight 175, flying low over the new york skyline hit straight at that second tower. just minutes from impact. the images that morning are so hard to watch. we're going to go back, we're going to open the vault on the second anniversary. here's the moment of impact of the south tower as it played on television. >> can you look out the window, see a guy at 4,000 feet? is he descending toward the building also? >> he's descending really quick, too, yeah. >> he just dropped 800 feet in one sweep. >> that's another situation. >> another one just hit the building. >> wow. >> oh, my god! that hit hard. >> another one hit the world trade. >> the whole building just came apart. >> holy smokes. >> this looks like it is some sort of a concerted effort to attack the world trade sent they are is under way. >> the p.a. system started going on. and there was an announcement, the event is contained to building one. everything secure in building two. you can stay or you can leave. i was between -- somewhere between 75 and 07, when the plane hit two. then that moment as this building is shake, i'm saying, this is it, i'm going to die. i'm going die. >> this is terrifying. awful. >> to watch powerless. is a horror. >> again, we are about to observe the second moment of silence,nd president bush will be speak. >> that's right. he is going to read from a letter abraham lincoln wrote during the civil war followed by a perform mance by yo-yo ma, as the reading continues, we're live streaming this on abcnews.com. 9:03, the moment when the second plane hit. >> and, david, you were talking earlier about the phone calls people were making, i was struck how many of them said things like, i'm calling because i want to make sure that you have a good life. i'm calling you to say, i love you and make sure that your life ahead is wonderful. >> for the folks that weren't able to answer. they left voice mails. one of the things they said, i'll be home. they didn't want people terrified they wouldn't get out of the tower, even though they knew, watching that morning and charlie, that morning and katie down the street, that was part of the cruelty, so many people had tuned in for that second momentnt had tuned in, sitting in front of the tvs and all watched when you pointed out this was clearly a concerted attack. that's the moment the nation realized this wasn't what we were hoping was an accident. >> you talked about the phone calls. i remember how chilling it was from the calls that came from the e anes themselves, a young man called his father and said, don't worry, dad, it's going to be quick. think about the final moments in those airplanes and the sheer terror, going through those planes as they were being hijacked and people had the presence of mind to actually call their relatives and reassure them. >> that was the thing about it, they kauls called thoho they loved and making sure they were oka okay. >> we are now approaching the second moment of silence, the moment the second plane hits the world trade center. >> gary eugene byrd. >> george, john bishop. >> jeffery donald. president lincoln not only understood the heartbreak of his country. he also understooded cost of sacrifice and reached out to console those in sorrow. in the fall of 1864, he learned that a widow had lost five sons in the civil war, and he wrote her this letter. "dear madam. i have been shown in the files of the war department the statement of the general of massachusetts that you are the mother of five sons who have died gloriously on the field of battle. i feel how weak and fruitless must be any words of mine, which should attempt to beguile you of a grief of a loss so overwhelming, but i cannot refrain from tendering to you, the consolation that may be found in the thanks of the republic, they died to save. i pray that our heavenly father may assuage the anguish of your bereavement and leave you only the cherished memory of the loved and lost, and the solemn pride that must be yours to have laid so costly a sacrifice upon the altar of freedom. yours, very sincerely and respectfully, abraham lincoln." [ applause ] my name is peter negron. my father worked on the 88th floor of the world trade center. i was 13 when i stood here in 2003 and read a poem about how much i want to break down and cry. since then i stopped crying but i haven't stopped missing my dad. he was awesome. my brother, austin just turned 2 when he passed. i've tried to teach him autopsy of the things my father taught me. how to catch a baseball, how to ride a bike, and to work hard in school. my dad always said how important it was. since9/11, my mother, brother and i moved to florida. i got a job, and enrolled into college. i wish my dad had been there to teach me how to drive, ask a girl out on a date and see me graduate from high school, and 100 other things i can't even begin to name. he worked in an environmental department, and cared about the earth and our future. i know he wanted to make a difference. i admire him for that, and i would have liked to talk to him about such things. ii have decided to become a forensic scientist. i hope that i can make my father proud of the young men that my brother and i have become. i miss you so much, dad. [ applause ] ♪ ♪ ♪ ♪ ♪ and what you're seeing now, is the families, for the first time, going to view that memoria memorial. >> i notice a number of them have pieces of paper. they are going to rub the surface and etch the names. >> jeffery donaald bittner. >> albert balewa blackman jr. >> christopher joseph blackwell. >> robin, i know you have to speak quietly, can you see the families move in toward the memorial? >> oh, yes, we can. we can see them streaming in. many of them with a piece of paper, because they were notified so they know where to go around the two reflecting pools to find that all important name that they are searching for. when the public comes later, they can go online and find out where these names are as well, but a number of the family members were already at that gate, wanting to be among the first to stream in, as they are, and a lot of thought, as we said rler, went in to where to place the names, how to place the names. with colleagues, with friends, with family members, and just trying to honor the family's wishes as best they can. >> again, just to describe to you, these acre-water falls. they are the largest man-made waterfall anywhere in the world. 26,000 gallons of recycled water, head over every single minute. when you are there, you can see patterns in the water. effervescent patterns in the watt theory seem to suggest memory. it drops 30 feet, then in the center, another 20 feet, and the 20 feet reflecting absence, the architect said. >> robin. >> because it has been so quiet, you can truly hear the rushing of the water, and it's so dramatic, also, it was not the intent, but at certain points of the day, there's a rainbow that can be seen in the pool, and it's -- i've seen it, and it's absolutely -- it just takes your breath away when you see that, and also when you witness the water falling in the middle. and just disappearing, the absence like that. such power and such grace at the same time. but you can clearly hear the rushing of the water, as you said, the largest man-made waterfall here in the u.s., because it is so quiet, it's even more poignant. >> families reach out just to touch those names. remember, again, it's been designed so they can touch the names at any time of year. there will always be a place that they can come to. that they c c call home as well. >> to give the sense of the level of consideration, they even made sure that any family member in a wheelchair could see over the top and see all of the way down into the center. >> the names are illuminated, that beautiful lights that would show them. i thought an extraordinary and respectful moment when all of us went down to do that report before this day, who asked not to film and show the names, so that the family members will be the first ones to see those names on this day, at that moment. you know, there's been some talk about why, perhaps, pieces of steel and remembrances of that terrible day are not on the plaza, and the designer said, this is a place of solemn. this is a place not of closure, but of moving forward, and all of those artifacts will be in the museum, and that will open a year from now. >> and of course the reflecting ponds, on the site, they are on the footprint of the two tower, david. you have been talking to survivor who have traveled down to see for themselves, some of them for the first time, because it happened ten years ago. >> and extraordinarily kind to invite us for the moment being back for the first time. lawrence jones was one of the survivors that we followed. so many people in the towers. it was their split-second difference that make the difference between life and death. you see this woman choking back her tears as she sees the the name here. they were on the 74th floor, they could watch the tower get hit. she was urging everyone on her floor to get down to the 77. she went down to the 77 floor, look add cross through the glass and wondered what this giant dark mass approaching the building was, and soon realize the second plane hit the flflr right above her. hearns florence jones, we met her just a few days ago. that morning, florence jones was heading to work. >> what a b butiful day this started off to be. and it descended into hell on earth. >> reporter: florence was on the 78th floor of the south tower, a manager. the north tower had been hit. this is what she told us on the first anniversary. >> to see the young people, doing the sign of the cross, and jumping, you are like, oh, my god. it's got to be awful up there for people to make that choice to want to jump. and know that you're going to die. and you can't pull your eyes away, as much as you'd like to, just out of sheer dignity for them. >> reporter: of the last 25 people out of the south tower, she was number 18. ten years later, she had not been inside ground zero, until she went with us. >> wow. >> reporter: ten years later, she still carries that searing image. >> i thought they w we just very brave people, to jump. i thought that was just an honorable way to go. >> and to honor them, ten years later, florence has now donated the shoes she had on that day, she saved them for ten years in a plastic box. they will now be in a museum at ground zero. >> the shoes she had on that morning, she saved in the plastic bag, still has the debris from the office and the journey down the stairwell. one of the things she talked about. was the kindness, even in the moments as they were trying to get out of the tower, her boss said he would carry the shoes for her, carried them down to the end, and at the end gave them back to her. as eveveone left the site. if there's any way to honor the faces she saw making the horrific choice in the next tower, this would be the s sll gesture. >> you heard them talking, from inside that stairwell. let's go back rigig now to ground zero, you see they are doing the etching, very much like people do at the vietnam veterans memorial in washington, d.c. >> the children etching them, it's remarkable when you think -- 48% of the people who died on 9/11, had children under the age of 18 behind who are now back there this morning etching those names. >> 76% were young father, were male, and many of them had kids under the age of 18. so many young fathers perished that day. >> so, as we head to a brief break before the next moment of silence, let's just watch and listen, silently at the families of those who are looking at the names of their loved ones. 343 new york city firefighters and 60 police officers lost their lives on september 11th, 2001. ♪ now you're in new york ♪ one hand in the air for the big city ♪ ♪ street lights, big dreams all looking pretty ♪ ♪ no place in the world that can compare ♪ ♪ put

[ male announcer ] and we think that's the best prize of all. ♪ looking live at the memorial down at ground zero, those family member, those children, touching the names for the first time. it's the first time the family members have been able to visit this memorial. every single name is etched around those waterfalls. and they are reefing out in love. many families taking those pieces of paper we saw before and efing that name, so they can take it home. >> that is exactly what the designer intended. that this would be a real touching, literally moment for family emms, throughout, not just today, but through the rest of time. >> of course, among those name, 343 members of the new york fire department and other fire departments, three of them retired. port authority, 37. new york police department, 23 and chris cuomo, i i want to bring you in. someone said, these were not lives that were taken. these were lives that were given. >> that is a beautiful way to say it. and so, so accurate. i remember that morning watching firefighters, lined up the avenues here, fighting to get into the scene, fighting to get into what everybody else was trying to escape from. and none of them would hold themselves out as heroic. it's important, that these names around the memorial are not put there alphabetically, they are done by association. while first responders numerically are not significant among the thousand, you'll see them in grouping, aterms of who they saved and different people. the ones we lost we must remember, but also cannot forget those who survived and fought. i want to show you a vignette of one such fie fighter named nicky cross, trapped on one floor of the north totor, those aboveveim and below him would not make it. this is nicky cross's story. >> i went up to thefo23rd floor. that's when the north tower shook. that's the south tower coming down. then we got an evacuation order, i got to the third floor and the stairway started vibrating and i heard the roar. you could hear it, rapid, like a machine-gun. i took my helmet and i just ducked in the corner. i got buried, things started hitting me. i was completely encapsulated. it was like being in a shell. i couldn't move. and the strange thing, it went totally silent. i was in a little tiny ball. i couldn't feel my body. i had no sensation, i thought for a couple seconds, that i might be dead. that may sound strange but having no experience being dead you don't know what you'll experience. i clicked my radio and moved my fingers and i said i i okay. i heard noise, people yelling out, bobby, jimmy, you okay? things like that. there were 14 of us there. we were siting there for about three hours. i see a light coming over my head. i'm looking at the sky. just -- needless to say, we started crawling towards it. >> you know, he laughs, because if you don't laugh, you cry. it's one of those situation. let me tell you something about mickey cross that makes him representative of so many firefighters, he got out, dusted himself out, he spent the next few dace here, trying to find people, trying to save people. when you talk to the firefighters, doesn't matter what they did that day, the most amazing thing, the thing that moves your spirit the moment. to a man, they say they would want to be here again. that is the kind of bravery, that you don't know where it comes from, but we have to embrace it and try to emulate it and we remember them all here today. >> how has the fire department recovered? this was the heart of the fire department. 343 people. >> you're absolutely right, george. it's unfathomable. there's a part testify that's impossible. they can't move on. there is something that is frozen in yourom a day like this. and there is difficulty going forward. many of them feel they are still dying today from 9/11, and they don't get the heroism and the type of harrowing that they do today as they did on 9/11, something for us all to think about but they take solace in one another. they are not here today. the nypd is not here in full rce, the firefighters are not here in full force but that gets them together. their brothers, sister, loved ones, that's what gets them through. >> that is one huge family. we're coming up now as the families continue to reach out, mashing the time when the third plane crashed into the pentagon. we do want to take a quick break. we'll be right back. a memorial was dedicated at the pentagon in 2008, and the memory of 184 people who died there on september 11th. -i love this card. -with the bankamericard cash rewards credit carar we earn more cash back for the things we buy most. it's 1% cash back everywhere, every time. 2% on groceries. 3% on gas. automatically. no hoops to jump through. that's 1% cash back on oscar. ...tony. oscar! 2% back on whatever she'll eat. 3% back on filling up this baby.

have been live autopsy morning this moment to come together and remember this moment to renew, as we think of those whose lives were lost on 9/11 ten year ago. >> that's right. all morning long we're taking you back to the sights and sounds of that day. you see the clock on the left-hand part of the screen marking each moment. at this moment the two towers had been hit. we are moments away from when american flight 77 came into the pentagon. at that time there will be a third moment of silence. right now the flight was closing in on the pentagon. they were beginning to get a sense how chaotic it was and how many attacks there could be. of course we're still facing terror alerts today. new york and washington under very high alert because of these concerns that at least three people may have come into the united states with the intent to launch a vehicle bomb against new york or washington. >> and, of course, in washington, at this moment, they have grounded 4,500 planes in the process of it. orders are going out, that they are to intercept planes into the air. martha raddatz is at the pentagon ceremony with us. martha. >> reporter: good morning, diane. i'm standing on the hillside where flight 77 passed over an slammed into the pentagon ten years ago. but i have to tell you, mixed with the sadness today is the sense of pride. right after that plane hit. right after people were evacuated and reporters were sent up here, people went back to work. there are 20,people who wo000 pk in that building. the very next morning they were back to work and they were about to w we war. we have been at war for ten years now, there is that sense of bride and sense of accomplishment what these people did. the families here are gathered. the memorial here has been open for three years. so they've seen those remembrance benches in descending order from the oldest person t tt was killed, a 71-year-old to a 3-year-old. that sense of bride and somberness this morning. george. >> they went right to work. secretary of defense donald rumsfeld right on the recovery line. we approach the moment of silence. we want totoring you back to the horrifying moment that flight 77 was headed toward the pentagon. >> i didn't hear anything, but i saw the aircraft above my head. 80 feet above the ground, close enough to see the windows and "american airlines" on . it read >> let me interrupt you for a second. we have fire confirmed at the pentagon and parts of the pentagon are indeed being evacuated. >> i remember thinking, the first one was likely an accident, the second one was an attack anded third plane was a declaration of war. i remember, thinking, here i am, the commander in chief, in a war zone. we had been attacked by an enemy right here in the heart of our capitol. >> you are looking live at the pentagon right now. secretary of defense panetta, vice president joe biden. outgoing chairman of the joint chiefs of staff. admiral mulli you heard presidet bush said he was under attack. he couldn't come back. they didn't know at that moment whether the white house was going to be hit. they know the pentagon, the heart of our military establishment had been struck, something that was just unimaginable. >> jake tapper, who covers the white house for us, a quick comment from you, before we hit the moment of silence. >> well, the president has left, and he's on his way to shanksville, pennsylvania for the flight 93 memorial. then he heads to the pentagon to lay a wreath there then a concert for hope at the kennedy center. but the president's day began with a briefing of the new terrorist threat. a reminder that the war that was declared on the u.s. that began ten clears ago today, continues. diane. >> as we prepare to observe the moment of silence, we'll tell you that governor of new york, andrew cuomo will be speaking. you will also be hearing from a little girl you might remember, because she had a red dress on, and at the time, she became the emblem of someone standing at a living monument to her mother, and she will be speaking as well, and we'll let you hear her story as she tells it, and james taylor will be singing. he, of course, sang at the concert for new w rk ten years ago. >> that's right. it will begin in a few seconds, mayor bloomberg will set up the moment of silence for the moment the pentagon was hit. >> 125 at the pentagon, 55 military and civils and 59 were on american airlines flight 77. >> the poet john dunn wrote, never send to know for whom the bell toll, it tolls for thee. to mark the twowo strikes again the buildings in new york, the fall of the two world towers, the crash of flight 93 over pennsylvania, and now, for at tack on the pentagon in washington, d.c. this year, we will hear the bell toll threeimes -- six times. there are those that say freedom of man is nothing but a dream. well, they are right. it is the american dream. in 1941, president franklin d l delanore roosevelt defined the freedom which the american dream is based. first, freedom of s sech and expression, everywhere in the world. the second is the freedom of every person to worship god in his or her own way, everywhere in the world. the third, is freedom from want, everywhere, in the world. the fourth, is freedom from fear, anywhere in the world. that is our goal, and our strength is in our unity of purpose. to that high concept, there can be no end, save victory. my names is james smith, retired new york city police officer. five years ago with my daughter patricia at my side, i told you about my wife, and patricia's mother, police officer moira smith who ran into the towers time and time again, to save as many people as she possibly could. moira sacrificed all that she had, and all the richness of life that still lay in front of her, in order to save just one more person. moirirwas killed when the south tower collapsed. since that time, patricia has grown, and blossomed into a lovely 12-year-old, the very picture of her mother. with her mom's smile and sense of adventure. our family has grown. patricia now has two little brothers to share her zest for life. five years ago,

[ male announcer ] progresso. you gotta taste this soup. once again, america remembers ten years later, and we're approaching two moments of silence, which occur in rapid succession. in the air, at this moment, united flight 93 already had the drama unfolding. the passengers, determining what was happening. and they were 20 minutes from washington. we have to remember when that plane went down. at the same time, on the ground, the heat, the 2,000 degree heat in places,n the towers of the world trade centers is starting to disintegrate the steel that is holding them up, and we'll approach the moment of silence as well when the firir tower goes down. >> it goes down at 9:59 a.m. that day. at that moment, united flight 93 heading towards washington, but the drama unfolding because the passengers on that flight are going to brink it down, they brink it down to shanksville, pennsylvania and josh elliott is there this morning. >> good morning to you, george and to you, diane. currently going on behind me the second day of the memorial here in shanksville, yesterday, attended by thousands, and really thousands of family members and friends of the 40 who lost their lives aboard united flight 93. it was a celebration presided over by vice president biden and former presidents george clinton and george w. bush. they came to dedicate the memorial, united 93 national memorial. as you can see here, there's actually a white wall of marble eteted on that wall, the names of the 40 souls who perished ten years ago today, tracing the final jagged path of the plane before it crashed. that field not the hijacker's intended target. when they took control of the plane they directed it right at washington, d.c., many believe to use as a tar got to hit the u.s. capitol building. and they might have succeeded if not for the courage and gravery and heroism shown by a group of ordinary soul whose collectively rose up and did something so extraordinary. and they did it for the simplest reason of all, they did it because they had to. and so, in doing so, as president bush said here yesterday. struck the first blows in the american war on terror. currently under way right now, is the ringing of 40 bells. the ringing and then the echo, done by family members, again, ofof the 40 who perished aboard flight 93. and the memorieie stand once again among those who had fallen in the nation's capital right there in lower manhattan. >> those were the heroes of united flight 93. at this point, united airlines flight 175 had already hit the south tower. it was beginning to melt. take a look. >> can you tell us what has just happened? >> yes, peter. four blocks north of the world trade center. the second building that was hit by the plane has just completely collapsed. the entire building just collapsed. >> it was 9:30 a.m. when he called. he told me he was on the 105th floor and he was trying to find a way out. he told me that he hadn't had any success. and now the stairwell was full of smoke. i told him that i wanted to be there with him. but he said no, no, he wanted me to live a full life. >> and as the smoke got thicker, he kept whispering, i love you, over and over. then i heard a sharp crack, followed by a sound of an avalanche. it was the building beginning to collapse. >> the whole side class lapsed? >> the whole building has collapsed. >> the whole building has collapsed? >> the building has collapsed. >> i called his name on the phone over and over. but i just sat there, pressing the phone to my heart. >> and, of course, as that tower came down, the cloud of dust, and chemicals and fumes, and the people inside, grabbing each other, clapping so each other can hear the way out as they tried to help save each other in that moment. >> it was something that no one could have ever imagined the tower would simply come down upon itself, in lower manhattan. it happened about a minute and a half from now at 9:59. we're going to come up on two moments of silence in fairly rapid suck sigs, at 9:59, the collapse of the south tour and 10:03 the flight united 93 crashed in shanksville, pennsylvania. that ceremony going on right now. and, david, we heard that phone call from the tower, the same kind of phone calls were coming in from flight 93. >> they were. it was so powerful to hear, family members on the plane were calling their family members on the plane saying, i love you, knowing they were taking control of the plane and knew their fate was crickly fortuned. >> todd beamer's "let's roll" has bebeme so emblematic of the couragen the plane that day, when he said we have to take these hijackers down. >> we'll hear a reading from chris christie that 700 people died in lived at the world trade center. that's half of the total there. he will come in and speak shortly as well. >> after the silence, you'll hear the bell ring four times for this fourth moment of silence, ten years after the attacks of 9/11. today, as you look over the walls of remembrance, we want to share withthou wordsf poet mary lee hall who wrote, turn again to life. if i should die and leave you hear a while, be not like others, undone who keep long vigil by the silent dust. for my sake, turn again to life and smile. nervi nerving thy and trembling hands do something to comforter hands than mine. complete these dear unfinished tasks of mine and i, per chance, may therein comfort you. ♪ ♪ ♪ ♪ ♪ may god bless those heroes we lost on september 11th. the brave men and women who responded so courageously, the heroes we've lost since that date, defending our freedom, and the men and women today who risk their lives here and abroad to defend our freedom. no words cried out so fully from the broken heart of our nation as those of a poem called "the names." it was written by the united states poet lariat, billy collins. he wrote it a year after the attack, and dedicated it simply to those who died and to their survivors, his last verse reads as follows. "names, etched often a head of a pin, one name spanning a bridge, another undergoing a tunnel, a blue name needled into the skin, names of citizens, mothers, and fathers, the bright-eyed daughter, the quick son. alphabet of names in a greenfield, names in the small tracks of birds. names, lifted from a hat, or balanced on the tip of the tong tongue. names, wheeled in the dim warehouse of memory. so many names, there is barely room on the walls of the heart. francis jude feeley. >> shawn bernard fagan. >> and the napes continue to be read this morning. >> i want to also talk you back to the moment that we were just remembering, the moment flight 93 went down in shanksville. this heroic moment for the people on that flight. take a look. >> i'm going to add to the chaos and trauma of the day, by saying a large plane has now crashed north of somerset county airport, about 80 miles southeast of pittsburgh. >> please tell my children that i love them very much, and i'm so sorry they -- i don't know what to say. there's three ys. they hijacked the plane, where it turn add round and heard that the planes have been flown into the world trade center. i hope to be able to see your face again, baby. i love you, bye. >> courage and optimism. led the passengers on flight 93 to rush their murders to save lives on the ground. >> when i took over the call, there was a gentlemen on the line, very soft spoken, calm, didn't hearny background noise. the line was still open. he turn from me to speak to someone else, and he said, are you ready? i couldn't hear their response. he said, okay. let's roll. >> passengers, and crew on board that plane, doing, what someone said, sosoiers, what they had to do. 12 of them able to call home and say good-bye to their loved one, before they did. let's go back to josh elliott to what they call that field of honor, josh. >> that's right. diane. that's one of the things that really did set this chapter of the story apart, the fact that the passengers aboard that plane knew what was happening to them. something else that sets it apart is the fact that, as you mentioned, this is a field of honor, directly behind me where the plane struck, is also a burial ground and will officially become one tomorrow. indeed this two-day dedication celebration of the flight 93 memorial will end today but for the manually members and friends, some thousand all tomorrow. will be a family burial as the coroner here has held remains of the 40 souls who lost their lives in an above-ground crypt for the decade. those souls will get what they have long deserved, a final resting place here in shanksville. diane. >> they are often not forgotten. that plane, united flight 93, they said, they believed it was heading, intended to go towards washington. just about this moment, diane, vice president cheney had given the orders, it let it be known that any plane headed toward washington could be shot down. we'll have word on that in a moment. but first, let's take a break. 102 minutes elapsed from the moment of the first crash not rth tower, to the collapse of both towers at the world trade center. çk vo: a breakfast worth waking up for. enjoy the sausage, egg and cheese croissan'wich today. only at burger king. the pain was so frustrating. i found out that connected to our muscles are nerves that send messages through the body. my doctor diagnosed it as fibromyalgia -- thought to be the result of overactive nerves that cause chronic, widespread pain. lyrica is believed to calm these nerves. i learned lyrica can provide significant relief from fibromyalgia pain. and less pain means i can feel better and do more of what i love. [ female announcer ] lyrica is not for everyone. lyrica may cause serious allergic reactions or suicidal thoughts or actions. tell your doctor right away if you have these, new or worsening depression, or unusual changes in mood or behavior, or any swelling or affected breathing or skin, or changes in eyesight, including blurry vision, or muscle pain with fever or tired feeling. common side effects are dizziness, sleepiness, weight gain and swelling of hands, legs and feet. don't drink alcohol while taking lyrica. don't drive or use machinery until you know how lyrica affects you. i found answers about fibromyalgia. then i found lyrica. ask your doctor about lyrica today. and, once again, we're glad you're joining us for this day of remembering and this day of rededication. as we look back at the attacks on 9/11, ten years ago. i want to check in now with robin roberts who is there by the reflecting pool at ground zero. robin. >> i have to say the blue sky has given way to some storm clouds that are coming in. and the families have been stopped from time to time, from streaming in to see the memorial. you have to keep in mind only so many can be accommodated at a a point.t. that's something the public has to keep in mind when it is open to the rest of the public, beginning at 10:00 a.m. tomomoow. as mayor bloomberg told me this week today, it's all about the families. it's very important that they were the first ones to see it. that there wasn't a grandd opening of sorts. today is for them. it's very important for many that the memorial be completed by the mashing of the ten-year anniversary as this happened. i have to say, the family member, even when they are stopped, they are so incredibly calm and patient and waiting for their turn to go in and allow them to start streaming in, again, diane. the way they leave little momentos, roses and other things they placed at the name of their loved ones. >> again, i want to point out, those who designed the site, they want people to have the experience of serenity and reflectio reflection. they set a limit of 1500 people, they will issue tickets, for anyone thinking of going, you don't have to fay for them. they are free, but they want to make sure the site is not too congested for you to have the experience you came for. >> we've seen that this morning, as the families approach those names. they have the private moment, amongst everything going on. where they communicate with their family members. katie you spent so much time with these families since 9/11. >> one of the most gut wrenching moments were those rows upon rows of flyers that were everywhere around the city, all of those family member, clinging. this particular is particularly heartbreaking two smiling faces of happier time, a kind of heart-breaking wanted poster, if you will, despite that, every day, hope was fading until reality finally had completely distinguished that. for some, especially some kids, like max giacconi. it was a reality he faced. . i believed h h was walkiki home. you think anything can happen when you're 10. >> joseph giacconi inspired what you were thinking. he loved family, food and music. despite a demanding job. he never missed a little league game or a chance to talk his son max to see his favorite team. >> he was a huge mets fan which made me a huge mets fan sometimes unfortunately but he introduced to me to amazing music that i still list ton today. >> reporter: when he turned 20, max realized he now lived as long without his dad as he about did with him. this spring he wrote in an's say, i had a dream about my father, recently. it was nice to see him, but he wouldn't talk to me. i don't remember his voice anymore. >> that must have been a very frustrating dream. >> you know, people say that that i talk to, but it wasn't. i don't expect to remember everything. it's just nice to see him. >> reporter: today max is a junior at the university of new haven. he's studying music production and writing his own songs. don't turn off the light. the night's not over yet. that's it. >> reporter: like many budding rock star, the ink just isn't on the page, but max's tattoos are about much more than teenage rebellion. >> this is a aually the first tattoo that i got when i was 15. >> twin towers? >> it's ixxi, which is 9/11 roman numerals. then my dad. >> that's your favorite photograph of your dad holding you. >> yes. it allows me to tell my story, tell the story of my dad and tell the world what an amazing man he was, and the man i've become. >> now, max is spending the semester abroad, he's studying in spain, he's a junior at the university of new haven. he told me he wasn't sure whether it will be harder or easier to be so far from home on this day, but he said, it doesn't really matttt. anniversaries aren't that meaningful, because he thinks of his dad every single day. and one more family member, diane, you actually interviewed this wonderful woman ten years ago on "good morning america," her name is beth murmurfy. i'm so glad i got to spend time with her. she's so full of light and such an amazing person. she's has two kids and has to cope with unbearable loss. but also appreciates the fact that she is lucky to be alive. >> i met him on his birthday, september 1st. and i sneezed, and he said, god bless you. and that was it, the rest was history. >> mr. and mrs. murphy over here. >> reporter: his friends called him thank kevin. after long days at work at marsh mclennon, he would come home to make dinner for his young family. he would even do the laundry. >> he was the responsible, caring, loving family. >> reporter: in august 2001 he would take on a a even bigger role when his wife, beth had a recurrence of melanoma and doctors found a spot on her lung. >> he said you can't die. he kept crying at my bedside and said, you cannot die. >> and three weeks later, when everyone is worried about you, kevn is gone. >> and i was faced, with, oh, my god, i have to raise these children alone and what if i die. that is probably the worst feeling in the world for anybody. >> reporter: two months after 9/11, a c.a.t. scan revealed the spot on her lung miraculously disappppred. >> in some way, do you think kevin was looking out for you? >> yeah, he was my cheerleader. >> today, beth murphy remains cancer-free. she sees the blessings kevin left behind in her children, connor and caitlyn, now 17 and 14. >> they are both looking at life in such gorgeous, beautiful ways, and i'm so blessed. >> reporter: on long island, where they lived together, on the beaches kevin love, we walked through one of the many 9/11 memorials that adds serenity to the coastline. >> i didn't receive a call that i found kevin, or any part of kevin, so i have places like this that help me heal. >> beth and her child enare doing really, really well. i met both her kid, connor and caitlyn, and they're terrific. beth is so lucky to be alive, considering what she was facing before her husband, kevin died. sadly, we know unfortunately, some families, with a surviving spouse, died, leaving the kids orphaned. she sees herself as very fortunate in many ways. >> boy, that is some story. kevin was lost in the collapse of the north tower. we're coming on to thatt moment at 10:28, the north tower did collapse. that's the sixth moment of silence in a few moments. let me bring david back. this, to me, is one ofhe most amazing stories of 9/11. a firefighter who actually survived the collapse fromm inside the tower. >> there were 18 survivors inside the tower collapse. we remember the finality of it all. but there was the miracle of stairwell "b" that emerged and captain jay jonas told us, he told his team your wives and children are over that twisted trench of steel that we're climbing over. i went over to fine what captain jonas is up today. after the towers had fallen, there emerged a tiny miracle. stairwell "b," a flight of stairs, somehow still standing, captain jay jonas inside that stairwell. this is what he told us one year later. >> i get choked up every time i talk about this. i remember cliff stadler in flick getting on the radio saying, we're coming for you, brother, we're coming for you. >> you knew the army of the new york fire department were coming for you? >> yes, they were. the troops were coming. >> reporter: ten year later and two promotions later, deputy chief jonas now, he still remembers who he told his men that day. as they climbed over that three-story trench of twisted steel. >> i said your wife and kids on the other side of that trench, just keep going, keep going. >> reporter: they did and they survived but deputy chief jonas, remembers every day, the men of fathers who were lost and he walked away. >> i wanted to be a fireman since i was a kid. other than playing centerfield for the yankees, this is the only job i ever wanted. >> still time for the yankees. >> still time. >> he also remembered the date the towers collapsed, as you mentioned, diane, the cloud that was hanging over the world trade center site really for days. he'll never forget. he was in that stairwell with the men, for a moment, he could see through the dust, the blue sky, that's when he said to the guys, we're going to get out of here. we've got to be able to pull this together. they thought it would be a hur cue l herculean task to get through that pile of steel. >> we'll pause to remember the second tower collapse. took six years to build and collapsed in 102 minutes. let's go back now with peter jennings at the moment it happened. >> next thing we have a problem aft north tower -- >> let's look at the north tower -- >> the north tower seems to be coming down. >> oh, my god. >> the second tower. >> there were masses of people waiting to the elevator, and for some reason, i decided to go back to the stairwell. so we went down, people were very calm. screams were coming down from the stairwell. emergency, emergency. and people were coming down. >> security personnel, and fire department people. >> now, those people were exhausted. and some of those eyes, and you could see the -- they knew something, that it was dangerous. they knew something. >> while there was no banging in the stairwell, those people were concentrated, focused on doing their job. while i was walking down, they were going up to their death, and i was walking down to live. >> it's hard to put it into words, and maybe one doesn't need to. >> both trade towers, where thousands of people work, on this day, tuesday, have now been attacked, andnd destroyed. >> thousands of people worked, of course, in those towers. but at the moment they both came down, all of lower manhattan vered in soot and debris, and people couldn't see five feet in front of their faces. christiane, at that moment, everyone in lower manhattan had to get out, had to find a way out. >> exactly. of course the fireman and police were together, but there were unsung heroes. the boat captain, this is a island, ferry boats, and an armada spontaneously created a biggest sea lift in history, bigger than dunkirk in world war ii, more than 500 people in less than nine hours. >> there were 50,000 people who worked in that area. had its own area code. zip code, 10048 at the time. the entire project was considered the largest construction project, the most dramatic construction project since the egyptian pyramids, that stood for a reach for the skies at that moment. i still remember walking down there, and getting there right after the tower collapsed, and seeing all around, up to my knees, papers that had drifted out of that building, and looking down and seeing schedules that people had made for things that seem so important at the time. >> you talk about the footprint of the world trade center. i was going down in a subway at the moment the second tower collapsed at the franklin street station. the entire subway station, the entire subway filled with smoke from that debris. no one knew what was going to happen. like so many other story, you see it right there. it was like a nuclear winter. that's what first went into my head, the phipps that we've seen, what was it going to be like after a nuclear attack? that's what lower manhattan felt like, yet, as we heard from the stories in the tower, everyone remained calm, remained orderly. >> people came out of their apartments into the soot and they had made peanut butter and jelly sandwiches, and they had water in their refrigerator, they were handing it out. one woman said this is all i i n do, but i'm going do all i can do. one of the faces we saw, one of the iconic faces was mayor rudolph giuliani, when we have a moment of silence, he will be speaking and paul simon will be singing. >> that's right. 10:28, the moment when that tower collapsed. this will be the sixth moment today we will hear the bell ring six times. that was the moment where mayor giuliani became america's mayor. that's what he was called for that response. >> he said he heard what happened. was having breakfast. had to get down to ground zero and had to walk two miles into the soot in order to make his way there. once again, we have a moment of silence coming up. it is the second tower, and it collapsed at 10:28:25, after standing for 102 minutes. it was the first tower hit. and it was the final moment. we watched together on 9/11. >> i wish you could be here to enjoy it with me. [ applause ] the perspective that we need, and have needed to get through the last ten years, and the years that remain are best pressed by the words of god, as inscribed by the book of eclees y ecclesiastics. to every thing there is a season. a time to be born, a time to die. a time to plant, to pluck up that which is planted. a time to kill, and a time to heal. a time it weep, and a time to laugh. a time to mourn, and a time to dance. a time to cast a ay stones, and a time to gather stones together. a time to embrace, and a time to refrain from embracing. a time to win, and a time to lose. a time to keep, and a time to cast away. a time to rend, and a time to sew. a time to keep silent, and a time to speak. a time to love, and a time to hate. a time of war, and a time of peace. god bless every soul that we lost, god bless the family members, who have to endure that loss, and god guide us to our reunion in heaven, and god bless the united states of america.
