At atlantas hartsfield airport theyre testing an Automated System to move passengers through security more quickly. David begnaud was there. Reporter atlanta is the worlds busiest airport. Thats why it was selected for this test case. The idea is to free up tsa agents so they have time for other things and if it streamlines the process and makes the lines shorter, thats a plus too. Heres how it works. You take out a basket from underneath, put it on top. Drop your luggage and then you put it on the automated belt. Let me give you the passenger perspective using the phone. If someone in front of you is taking a little extra time to take her shoes off, maybe theyre distracted. Your bag is already on the way, on the belt, headed for the machine. As you come out on the other side, youll notice something new. If your bag gets flagged for water or Something Else they want to check, what happens is it gets kicked to another Conveyor Belt on the lefthand side so it doesnt tie up the bags that are good to go. If your bag is good to go, you grab and it youre on your way. Theyre testing out this system in london and in amsterdam. Were told so far over there, its working very well. Charlie, depending how well it works here in this test case over the summer in atlanta, it could be fast tracked around the u. S. Thanks, david, well done. Overseas, about 100 migrants are missing in the mediterranean off libya. Their boat capsized during the perilous journey from north africa to a better life in europe.

The italian navy brought the rescued migrants and refugees into port today in sicily. As the weather improves, thousands more are making this dangerous journey.

Aid groups say the number of unaccompanied minors making the journey to europe is on the rise this year. And the International Organization of migration says 1,370 migrants have died making that crossing in the mediterranean. Seth doane in rome, thank you, seth. Such desperation and tragedy. Two navy f18 fighter jets crashed off the North Carolina coast. All four crew members bailed out and escaped with minor injuries. The coast guard reported the planes collided in midair during a training run but the navy said only that it was an inflight mishap. In japan president obama and reporter the images are haunting. But for susan archinsky and husband tony, theyre also personal. A stark reminder of the american prisoners trapped in hiroshima when america detonated the first atomic bomb. One of them was susans uncle. How close were they . To the center of the bomb . Very close. Right underneath it. Like 900 meters from the epicenter. Reporter the explosion ripped through the city, killing 80,000 people instantly. 12 p. O. W. S were held captive inside a Police Station that stood here. Archinskys uncle norman brousett was a 19yearold gunner whose plane had been shot down over the sea of japan nine days earlier. They were hit by antiaircraft artillery and they landed in the water, smoking. The last anybody knew they were floating in the ocean.

Baylor university fired its head football coach today and demoted its president Kenneth Starr. The shakeup follows a legal review that found the Baptist University mishandled several cases of Sexual Assault involving Football Players. Heres anna werner. Reporter the report faulted baylor for a wholly inadequate response, saying the university failed to take appropriate action to respond to reports of Sexual Assault reportedly committed by Football Players. It said two University Administrators directly discouraged complainants from reporting, and in one case retaliated against someone who reported a Sexual Assault. The university responded today by stripping the title of president from Kenneth Starr, who was the onetime special prosecutor who led president clintons impeachment trial involving white house intern monica lewinski. And they fired football coach art briles. Briles is credited with turning around the football program. But today some are questioning, at what cost . Baylor Board ChairmanRichard Willis apologized during a teleconference. Were deeply sorrowful about these events. We were just horrified by the extent of the acts of Sexual Violence on our campus. Reporter at least six women have accused eight baylor Football Players of violence. It is not enough. Reporter Jasmine Hernandez sued baylor in march claiming after she was raped, the school ignored her pleas for counseling and justice. The player who assaulted her is now serving a 20year sentence. Hiding these very egregious acts of crime only allows them to continue further and to continue repeatedly. Reporter Kenneth Starr remains baylors chancellor and a tenured law professor, but charlie, baylor told reporters on that teleconference call that he will no longer have any operational responsibilities.

As you may remember, hulk hogan recently won a lawsuit against a website that posted a secretly recorded sex video of the pro wrestler. Turns out hogan had a heavyweight in his corner for the courtroom match. One who was rich and motivated. Heres john blackstone. Reporter behind the highprofile court case of hulk hogan versus the gossip website gawker was a secret. Hogan, whose real name is terry bollea, got nearly 10 million to pay for his legal team from silicon billionaire peter thiel. In a statement he said, i am proud to have supported terry bollea against a bullys gross violation of privacy. Gawker built its business on humiliating people for sport. Thiel, founder of paypal and an early facebook investor, was targeted by gawker in a 2007 posting that outed him as gay. Nick denton, gawkers founder, is unapologetic about his brand of news. Gossip is the version of news that the authorities or the celebrities or the officials dont want people to know. Its the unauthorized version. Reporter thiels support helped hogan win the 140 million award that could now put gawker out of business. It is also raising concern that money from thiel and others like him could silence free speech. It really isnt a question can someone else fund your litigation . Of course they can. Reporter miriam smith is an expert in media and internet law at San Francisco state university. Does it make a difference that peter thiel kept his participation secret in this . It would be best to know whos funding the litigation. It would be best to know whos paying for what. Reporter late today both are trading jabs. Gawker posted a letter saying thiel is on a decadelong scheme for revenge. Thiel says hes not looking for revenge, just for a deterrent. Up next, a place that sure looks like its in a galaxy far, far away. The force is not all that was awakened in the most recent star wars movie. Mark phillips is on an island that just woke up from history. Reporter in the movie, rae and chewbacca flew the millennium falcon to an island that looked like something only a hollywood set designer could dream up. In real life, you need a boat to get to Skellig Michael. Seven lumpy miles off the southwestern tip of ireland. The island has a history that goes back to the dawn of civilization. But its never had to cope with anything like this. Rae found Luke Skywalker. We found bob. Welcome to skellig. Thank you very much. Here we go. Reporter bob normally guides tourists up the more than 600 steps that climb to the top of this unesco World Heritage site. Only one way up, i guess. Thats right. Reporter steps that take you past breathtaking views. Along heartstopping ledges and past the puffins to the peak where about 1,500 years ago industrious monks built a monastery that was occupied the next six centuries. The magical thing to me is the fact that you can look in these dark doorways today and look in at exactly what sixth century men looked at. Reporter sixth century men never looked at anything like this. Yet thats exactly what 21st century tourists have come to do. Janet moore beamed up from tampa. We were planning to come to ireland before even the star wars movie came out. And then that clinched it. Reporter it clinched brian and Ellie Summerfield from michigan. We thought it would be fun to come out here and pretend i was skywalker and she was whats her name . Rae. Yeah. Reporter the force, the old force, has always been strong here. But a new kind of force, some fear, may be the undoing of this place. One brief sequence in a movie may have undone 1,500 years of real history. Paddy bush is a local poet. If you get crowds of people who simply want to visit a movie set, then skellig is no longer skellig, its Something Else. Reporter 180 tourists are now allowed each day. More may be too much for this place. Sometimes the place seems too much for them. Yet the draw of the real past and the imagined future keeps them coming. So the force is still here. I think the force has been here for a very long time. Reporter and the irish tourist board hopes the force stays with them. Mark phillips, cbs news, skellig. That is the overnight news for this friday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning.

Aaa estimates that 38 million americans will go at least 50 miles from home over the next few days. The vast majority will travel by car. But more than 2. 5 Million People will be taking to the skies. And the trouble is expected to begin at the Airport Security gates. Tens of thousands have already missed their flights this year because of the long security and although the tsa is trying to address some of those problems, few of their solutions will be in place today. Kris van cleave reports from reagan national. Reporter there is still a whole lot of concern about the lines this weekend and throughout the summer. Now the tsa says there are making progress at reducing wait times at major airports. But to really solve this problem is going to take time, money, and more people. Thats completely unjustifiable. Were in our own crisis right now. I stopped that. Reporter damage control on capitol hill wednesday following fury over historically long lines at airports nationwide. Tens of thousands have missed flights. Some were left sleeping on cots at chicagos ohare.

My goal is to open those precheck lanes open throughout the day things like that shouldnt take an act of congress. Is as you know. No it took an act of me and i said, thats the way things have to happen. Reporter tsa is testing this automated screening lane at Atlanta Airport to see if it will improve efficiency and speed up lines. We hope its going to cut into wait times over the long run but this is not the quick fix for summer wait times. Reporter in the first five months of this year tsa screened 449 million travellers, up 57 million from the same period in 2015, with 5,800 fewer screeners than 2011. As the agency rushes to hire nearly 800 additional screeners by midjune, k9 units are being redeployed to busy airports and 34 million has been authorized for overtime ahead of the holiday weekend. Have you done enough to address the wait times . Do people need to get to airports three hours early . We put a lot of resources in. Were still focused on security. I think weve already seen a dramatic improvement. I would tell people to be aware theres going to be a lot of people in airports. I dont know what the right time is to get there but i think youre seeing dramatic improvement. Reporter the airlines are spending millions of dollars to hire private contractors to help with nonscreening activities around checkpoints, that includes pointing people to the proper lines, returning bins to the front, that sort of thing. Later this morning executives from the airlines and the airports are going to be testifying before congress about how all of this is impacting their business. Its now a done deal.

Hillary Clintons Campaign remains in damage control after the state departments scathing report on her use of a personal email server while she was secretary of state. The office of Inspector General says there is no evidence she ever requested or obtained guidance or approval to use an email server in her home. Reporter clinton says she has actually been incredibly open, handing over about 30,000 emails. But the report said she should have turned them over when she left the state department in 2013, not after she was asked for them a year and a half later. And it added she shouldnt have had to turn them over at all if she had only used the Department Email system. Its not an issue that is going to affect either the campaign or my presidency. Reporter clintons first Public Comments about the critical report came in an interview with univision in los angeles. Nothing has changed. Its the same story. Just like previous secretaries of state, i used a personal email. Many people did. It was not at all unprecedented. Reporter but the state departments Inspector General examining the records of secretaries of state dating back to Madeline Albright said it could only identify three cases where officials used nondepartmental email systems on an exclusive basis for daytoday operations. Clinton, colin powell, and a former ambassador to kenya. The departments guidelines were that personal accounts should only be used in exceptional circumstances and the report said clintons use of private email is not an appropriate method of preserving a federal record. Everything i did was permitted. There was no law. There was no regulation. Reporter the report contradicted that assertion saying that Diplomatic Security officials did not and would not approve her exclusive reliance on a personal email account because of the security risks in doing so. State Department Staffers who did raise concerns about instructed never to speak of the secretarys personal email system again. She had a little bad news today. Reporter in anaheim, donald trump was quick to capitalize. Not so good. The Inspector Generals report, not good. Insider trading is one of the hardest crimes to detect. It happens in whispers and phone calls. Behind closed doors. One trader who did get caught turned into a government witness. She helped bring down one of the Biggest Hedge Funds in the world. Bill whitaker has the story for 60 minutes. You are pushed and pushed to get this information. You know, you get the highfives after the trade. I was sent flowers after one of the trades. A big thank you, a huge bouquet, thank you. Sounds like you guys are in a bubble trading all this information while we sit and look at it and say, thats breaking the law. Absolutely, we were breaking the law. Reporter breaking the law by obtaining confidential information from friends in Silicon Valley connected to google and polycom and other tech companies. In two years, roomy khan made 1. 5 million from illegal trades alone. Her friends and associates made an additional 25 million off her tips, investigators found. It was easy money. Just like, if you are taking an exam tomorrow and somebody hands you whats going to be on the test, its easy to get an aplus. Reporter roomy khan shared her tips with selfmade billionaire Raj Rajaratnam who built one of the Biggest Hedge Funds in the world, the 7 billion galleon group. Federal authorities said raj rat natural made over 72 million from illegal tips from roomy khan and other sources. The two met back in the 1990s when she was working at intel as a product marketer and had access to proprietary company information. Raj rajaratnam tapped her for the inside information so he could trade on it. Then he started asking me about, how is business . And i used to have access to intels top customer microprocessor bookings. I started giving him this information. So you started feeding him inside information from intel . Absolutely, absolutely. Reporter roomy khan was so brazen she used intels fax machine to send him confidential data about product demand. She says rajaratnam referred to inside information as the edge. She was such a good inside source, she said he offered her money to stay at intel. Ill give you 100k just to stay there. I dont remember the number he offered but he did offer me money to just stay there and keep giving him information. And i said, theres no way. Reporter roomy khan came to the United States from delhi, india, on a scholarship at age 23. She earned three graduate degrees before joining intel. But she longed for the action of wall street and set out to build her own fortune. At the height of her success, she says she was worth 50 million. Khan moved into this 10 million gated estate in the heart of Silicon Valley. She was living the life she wanted where money was no object. Jewelry, paintings, anything that you can think of. You had it all . We had it all, yes. The high life . Absolutely. The sort of life we see in the movies with the hedge fund investors. Probably. Probably. Reporter one purchase from that time still makes her light up. The 17carat famous diamond ring. The famous diamond ring cost how much . I think 1. 7 million. Reporter she explained to us just how the biggest money could be made. When the predictions of wall street were at odds with the inside information. So the most money you make is when your analysis is totally and opposite to what your edge is telling you. The inside information . If you have a really great source. Reporter roomy khan had a really good source who knew what was going on inside google. A friend who worked for a firm that prepared Googles Press releases and who told her the companys quarterly income would be lower than expected. She told me they were going to miss the quarter. You made money off it . I did, i made 500,000. Reporter she shared the information with galleon chief Raj Rajaratnam who made 8 million betting against google just before the price dropped. And youre making good money but hes making far more. Whats your motivation . Well, i had access to raj. So i had that access to the billionaire Biggest Hedge Fund on wall street. And that was worth a lot to me. Reporter her relationship with the Hedge Fund Titan would be worth a lot to the government too. Roomy khan didnt know the securities and exchange commission, the s. E. C. , had launched an investigation into rajaratnam. Former s. E. C. Attorney Andrew Michaelson was tracking his texts and trades. We did see mr. Rajaratnams instant messages. Communications where he would say, amds revenues are going to be x. Before amd itself announced them. And they were accurate. Mr. Rajaatnams predictions were accurate. Reporter michaelson joined the s. E. C. In 2006 and this was one of his first cases. He remembers combing through stacks and stacks of galleons trading and phone records, instant messages, and emails. How many documents are we talking about . Hundreds of thousands. Hundreds of thousands . Sometimes youd have to sit there with a ruler to make sure youre getting exactly who is talking, what phone numbers calling which phone number at what time. So youre connecting the dots . Were connecting the dots. Then the next dot to connect is wheres Raj Rajaratnam getting this information . Reporter finally, after six months of searching, they found the needle in the haystack in a single careless instant message from roomy khan. I texted him and i said, dont buy polycom. In writing . It was a text message. Electronic writing . Yes. And it said, till i check the guidance. Youre saying, dont do anything until until i get my information. Until i call my inside guy and get this inside information . Right. Reporter it was the piece of evidence fbi special agent b. J. Kang thought he could use to turn roomy khan into an informant against rajaratnam. She was an insider, she knew all the players, she worked for galleon, she knew raj. Reporter he paid a visit in november 2007. Two people knocked on my door and flashed their badge. And my heart sank because i just was like, oh my god. She knew we were dead serious. She knew why we were there. She knew this wasnt going to go away. Reporter kang showed her the polycom message she had sent to rajaratnam. When they showed me this text message, i knew this was over. It was very easy for them to connect me to the executive at polycom. Reporter she knew she had to cooperate. Starting in late 2007, she began to educate the feds on the hidden world of some of wall streets biggest players. We didnt have a very good understanding of what the hedge funds were doing. You didnt understand completely what you had . No, absolutely not. She kind of drew out the roadmap for us to say, this is what theyre doing. This is how theyre doing it.

Skellig michael played a starring role in the movie, now fans are coming from far and wide to take a firsthand look. Mark philips did too. Reporter it looks like something only a hollywood set designer could come up with. Yet when rae and chewbacca flew the millennium falcon to this dramatic rock in star wars, they werent flying to a fictional place. Skellig michael is the real thing. If you dont have a spaceship you need a boat to cross the lumpy seven miles of open ocean off the southwest tip of ireland. Also you get hugh and joe instead of rae and the wookiee. When you land you get bob. Nice to see you. Welcome to skellig. Reporter the tourist guy. Like nowhere ive ever been. Reporter bob knows all about a place so special its been declared a unesco World Heritage site. Not just for its spectacular beauty. And its enchanting wildlife. But because somewhere around the sixth century a. D. , a small group of adventurous devout christian monks established a monastery here. And generations of monks stayed for at least 600 years. The monks beehive huts and chapel and graveyard have remained essentially as they were. Four, five, six, seven, eight. Does the 600 count these . Reporter to visit these wonders you have to climb. Yep, here we go. Im not even going to count. Reporter more than 600 steps that the monks carved into the cliff face. By step 400 you can hear your heartbeat. When rae came here she wasnt interested in the sights. She came on a mission. We came because rae came. And to see what star wars has done to the place. By the magic of the movies, theres no millennium falcon now. Rae came to find Luke Skywalker. It was a makebelieve encounter that has had real consequences. Luke skywalker may have thought Skellig Michael was a good place to come and hide, but he brought the new force with him and others think that might not be good for the place. Where skywalker has come, others have followed. No spaceship but lots of little ships have brought an everincreasing stream of tourists to the island. A bargain at 60 euros, about 67 a pop. Theyve been drawn certainly by its enduring charms. But also by its new hollywood notoriety. Janet moore came all the way from tampa. We were planning to come to ireland before even the star wars movie came out. Then that clinched it. Reporter and that also clinched it for brian and Ellie Summerfield from michigan. We thought it would be fun to come out here and pretend that i was Luke Skywalker and she was whats her name again . Rae. Yeah. Reporter even if the visit can be a challenge for some, two people, both americans, have fallen off these steps and died here. But its not just the numbers that are worrying. Its the fear that Skellig Michael, a special place for its history, is being confused with Something Else. You think theres been some compromise now, that people are coming to say, oh, thats not where a dozen monks lived 1,000 years ago, thats where Luke Skywalker landed the millennium falcon . The monks were here 1,300 years ago and people still know about them. I dont know how long people will know about star wars but they may know about it for a very long time. Reporter especially since scenes theyve already filmed on the island feature in the next star wars movie too. Those who brave the trip here, like fran politi from San Francisco, hope all this fame doesnt change the place. You know, not too many railings. Nowhere to buy ice cream. No bathrooms. Thats good. If its good enough for luke, its good enough for you . If its good enough for the monks, its good enough for me. The summer olympics in brazil begin august 5th.
