Brian williams. Special good evening to our viewers in the west tonight. And as we come on the air, a breaking story along the atlantic coast. Because previous might time rocket launches have been so spectacular to watch, a lot of folks from the carolinas to maine were indeed ready to watch tonight at 6 22 eastern time when an unmanned rocket launched from Wallops Island on coastal virginia carrying 5,000 pounds of supplies up to the International Space station. But it didnt clear the tower by much before it fell to earth and exploded. We get a late report tonight from our National Correspondent peter alexander. Four, three, two, one reporter it was an unmanned antares rocket on a resupply mission to the International Space station when seconds after liftoff from Wallops Island, at 6 22 this evening, something went very wrong. Team be advised stay at your consoles. Reporter the rocket with 5,000 pounds of supplies on board exploded in the night sky. Nasa reported no loss of life, but extensive Property Damage on the ground. The launch was supposed to be visible along much of the east coast as it made its way to space. Many planned to follow the flight path on line. Instead of explosion could be seen on radar. The crew on board the space station was supposed to send it back with bag of garbage. American and russian rockets are the only way to supply the station. Tonight no word on what this means to nasa and how much of a setback it represents to the space station. Peter alexander, nbc news, washington. Now to the ebola fight. And here is what Public Officials are up against in trying to tamp down the panic over ebola. The nurse who spent the weekend in a quarantine tent in new jersey after returning from africa is home in the state of maine tonight, and because her boyfriend lives in ft. Kent in northern maine, the local paper there says some patients have canceled elective procedures at the local hospital. Even though this nurse, kaci hickox, has never been there, has no plans to go there and is not sick and may not be anywhere near there. The president today said people like her need to be applauded, thanked and supported for their work with ebola patients in west africa. And in a moment well see the scope of that fight right now. We begin tonight with the latest in this country. The release of a dallas nurse from the hospital. Here is our National Correspondent kate snow. Reporter dallas nurse amber vinson is headed home. Im so grateful to be well. Reporter after speaking with vinson by phone, president obama urged americans to keep perspective. Of the seven americans treated for ebola so far, all have survived. Reporter but his sharpest message aimed squarely at states enforcing mandatory quarantines for Health Care Workers returning from west africa. We dont want to discourage our Health Care Workers going to to the front lines and dealing with this. We dont take anything for granted. Reporter this afternoon new Jersey Governor Chris Christie defended his decision to keep a nurse who returned from sierra leone in a tent for three days. Looks like youre going to have to defend this. Whatever. Get in line. Ive been sued lots of times before. Get in line. Ill be happy to take you on. Reporter that nurse is back in her home state of maine tonight. A new Facebook Group popped up overnight protesting her return. But in a strongly worded editorial in the new england journal of medicine doctors say quarantining Health Care Workers is unfair and unwise because ebola is so hard to transmit early on even with a fever. At the time that individuals have the first symptom such as fever or malaise, the initial first symptom on that first day, the Current Evidence suggests that the risk of contagion is extremely small. Reporter after those first signs of ebola, fever and fatigue, as days go by the amount of virus in the body grows, leading to symptoms like vomiting and diarrhea. The sicker you get, the more contagious. Thats why, experts say, its unlikely dr. Craig spencer exposed anyone to ebola when he went bowling. Hes now in serious but stable condition. The only american still fighting ebola. Kate snow, nbc news, new york. This is Chris Jansing in liberia. From 10,000 feet, the osprey helicopter descends into the heart of the ebola epidemic. For u. N. Ambassador samantha power, its a closeup look at americans on the front lines of the fight. We service the remote regions of this part of liberia. Reporter the u. S. Navy set up a mobile lab thats cut the agonizing wait time for ebola test results from six days to four hours. Then a rough ride into the jungle to an ebola treatment unit. The staff includes ten americans. You cant really see it from here, but the other side, thats our triage area. Reporter we saw it from outside a barrier at a safe distance. Recruiting Health Care Professionals to work inside has been a real challenge. Even the humanitarians are afraid to come here. Reporter why . Its new. Its invisible. Reporter i talked about that fear with liberias americaneducated president ellen johnsonsirleaf. Are you worried americans will stop coming . Im not worried, but im a little bit concerned because we believe its an overreaction. We understand the fears. Reporter so does samantha power. A mission in the interests of the american people. Reporter boosting morale has been a big part of this trip. Today at this Ebola Treatment Center being built by the u. S. Military. Designed for war zones, the unit has been adapted to treat Health Care Workers with ebola. The staff arrived just yesterday. 70 members of the u. S. Public health service. Weve all been a little bit nervous. How can you not be . But you temper that with your professionalism and your expertise and your training and thats all behind you. Reporter for ambassador powers seeing the fight against ebola here in liberia up close is critical to assess whats working and what isnt. Its also exhausting. Shes getting about three to four hours of sleep a night. Brian . And late eletter from the department of homeland security. Federal buildings, not just in washington, but some all across the country, are now being ordered to beef up their security. We want to get more on this from our justice correspondent Pete Williams in our d. C. Newsroom. Pete, good evening. Good evening. Officials say this is not the result of a specific threat. Instead they say its a response to the growing calls for acts of violence. For weeks now, isis has publicly called for attacks on u. S. Targets overseas and here at home, in propaganda videos and jihadist websites and suggested attacks on government buildings and installations. Add to that last weeks shooting in canadas capital city and u. S. Officials say the reasons are selfevident. Homeland security secretary jay johnson says prudence dictates heightened vi eed vigilance. It will range from most officers on guard to more sensitive settings on metal detectors. Pete williams, thanks. When we were last on the air last night, a wave lava was closing in on a residential neighborhood in hawaii on the big island which has been on alert as recesidents have been evacuated. Sadly the fears have been realized. As lava from the kilauea volcano now pushes into that neighborhood. And nbcs Hallie Jackson is on the big island for us again tonight. Reporter this is the first big casualty of the pahoa lava flow. The first structure burned, but it wont be the last as this 2,000degree molten river oozes over town. Its been on its way for weeks since a volcanic eruption in june. Now finally here and people preparing to lose their homes are preparing for closure. So you will actually allow these folks to watch their homes burn . Yes. An opportunity for them to go through a grieving process with losing what in some cases may be generations have gone through homes. Reporter and for the youngest generation here, a new school. Weve been preparing for it. So, unfortunate, but were ready. Reporter at night the lavas red glow, an ominous presence. One the lee family can see from their yard. Five generations in this house . Their house may be next. Theyre doing everything they can to divert the flow, bulldozing a massive berm in their backyard made of rock, built on prayers. You think it will work . It might. Were hoping. Reporter hope will not stop whats coming. The lava that could cross the areas main highway any day now. And while officials are building out alternate routes shane turpin is so worried about the flow, he is moving his business closer to the town of hilo just in case he ends up on the wrong side of the lava. Theres going to be no way to get tourists and locals or anybody that wants to go out on our boats or on a hiking tour out to this area. Reporter a way of life under fire, a redhot river unrelenting. Hallie jackson, nbc news, pahoa, hawaii. There was a heartbreaking scene today to our north in hamilton, ontario, canada. The funeral for Corporal Nathan cirillo, the soldier shot and killed at canadas National War Memorial before that attack on Parliament Last week. Thousands of people lined the streets to view the procession of soldiers carrying cirillos coffin to the church. His 5yearold son marcus followed just behind wearing the same red and white glengarry hat worn by his dads military regiment. Another somewhat surprising theological statement from the head of the Catholic Church to report on. It now appears pope francis is open to the theories of evolution and the big bang. He told a vatican audience that neither idea conflicts with the idea of creation. He also says, quote, god is not a magician with a magic wand. In this country, just one week from tonight, theyll be counting the votes. Well be here and on the air calling the races, and when its all said and done, we could be looking at a very different balance of power in this country. Tonight chuck todd, moderator of meet the press, is on the road and reporting on one of the most closely watched senate races in georgia. Reporter out here in the backroads of georgia where democrats havent won a statewide election in ten years, the race for the senate is neck and neck. No ones happy with the party in charge. They havent done anything. So maybe a change might help. Reporter and that makes georgia one of the key races to watch. With a week to go, control of the senate is at stake. Today, georgia, iowa, north carolina, where they spent more money than anywhere, and a half dozen other states are simply too close to call. Republicans want it to be all about an unpopular president. This election is about what to you . Its about getting president obama out and getting a republican in. Reporter personal message to the president enjoy your last two years. The past six hasnt been good. Reporter democrats are trying to localize the senate races, accusing opponents of outsourcing jobs in georgia, failing on education in north carolina, and in iowa, where they could elect a woman for the very first time, ignoring womens rights. This is important. This is important, yeah. Right. Reporter the one theme thats repeatedly surfaced in conversations with voters on the road is anger and frustration with the bickering and gridlock in washington. But voters arent falling into familiar patterns because they feel that theyre being ignored by both parties. Whats your message . Just compromise. Be willing to work across party lines. We can work together, you know, things will get done better. Were just getting the fight back and forth. So its time to start replacing people. Reporter the magic number to know, brian, is six. Republicans need six senate seats to get control, but we may not know on election night, thanks to likely recounts because of close races, runoffs in georgia and louisiana, if nobody gets 50 , and the fact that it could take weeks to get the actual count right in alaska, and we may not know control of the senate until january of next year. Miles to go before he sleeps. Chuck todd on the road tonight in smyrna, georgia, thanks as always. Still ahead, have millions of at t customers been deceived . If your phone service is running slower than you thought it should, tonight the feds say we may know why. Later making a difference in one of the best known music towns in america. A kid who made it big paying it forward back home to keep the music alive. Tonight at t wireless is in trouble with the government again. Earlier this month, as we reported here, the company reached a 105 million settlement with the feds regarding unauthorized charges on phone bills known as cramming in the business. This time at t is accused of charging millions of customers for unlimited data plans youve heard of that, right . Well, it was actually reducing their data speeds to the point where they couldnt fire up some of the features on their phones. Our report from nbcs tom costello. Reporter the government says its happened to millions of at t customers going from lightning fast to turtle slow. Maurice turner says it caught him off guard. In the last couple of years, ive noticed that in the middle of my cycle, my billing cycle, it gets throttled. You know, the data slows down to a crawl. Almost like going back to dialup speed. Reporter for 30 a month hes been paying for the unlimited data plan. But the government accusing at t of reducing or throttling data speeds on its biggest data customers by up to 90 . Even though consumers would pay for unlimited data, the throttling began after they used as little as 2 gigabytes in a billing cycle making it difficult or impossible to surf the web, use a gps or watch streaming videos. The government alleges 3. 5 million customers were throttled more than 25 million times. Unlimited means unlimited. If you slow down the service of customers who believe theyre getting unlimited data, theyre not getting unlimited data. Reporter at t today called the ftcs allegations baseless saying we have been completely transparent with customers since the very beginning. We informed all unlimited dataplan customers via bill notices and a National Press release and Text Messages of a change in terms. At t says only 3 of its customers are affected, but the ftc calls it a classic bait and switch. Signing up customers and promising a service, then changing the terms while still under contract. Anyone who has had at t Unlimited Service since 2010 or earlier could be affected. Tom costello, nbc news, washington. And we are back in just a moment with one of the images of the day. The house is real, but its not the real white house, and whats it doing in iraq . If youre ever in erbil, be sure to see the white house. This one is the creation of a wealthy local kurd named Shihab Shihab who says hes always admired the real one in washington for its beauty and simplicity. Theres a lot of trophy houses like it in erbil where life has been good for many. And thats why they have their defenses up to defend their city against isis recently. The man who invented the board game operation now needs one himself. John spinello invented the game back in college. Its been rattling nerves for 50 years as we hunt for bones with tweezers hoping to beat the buzzer. The problem is spinello sold the rights to it for just 500 back in the day. He was young. These days he doesnt have the money he needs for oral surgery he badly needs. Some toy designer friends of his have started a Crowdfunding Campaign to cover his anticipated 25 grand in medical bills. Hes also auctioning off the first prototype of its kind to raise money. Thats in december. Theres only one way out of the live music business after a brilliant career. And for the allman brothers that means one last show tonight at the beacon theatre here in new york. Their northern musical outpost for the last two decades. Theyve been through a lot in 45 years including the death of brother duane allman. After all the loss, addiction, and tragedy and triumph, with greg still at the helm, theyre going to go down swinging tonight. It all ends this evening for this Great American band. When we come back, a music lesson from a young standardbearer of new orleans jazz in tonights making a difference report. In our making a difference report tonight we happily go to new orleans, the place where in good times and bad, in addition to a beverage or two, its the music that keeps the city together. And one of the biggest stars of this generation wants to be sure the next generation knows which notes to play. Our report tonight from nbcs kevin tibbles. Reporter in new orleans, it bubbles up from the street. No wonder they call it the birthplace of american music. And these Young Players are tapping into that tradition. My dads a musician. My grandpa was a musician. Reporter you want to keep it alive . I want to keep it alive, yeah. Reporter their tutor is troy andrews, who learned to play at the age of 4. Taught by the grassroots masters in the treme neighborhood where he grew up. Andrews, who has now made a name internationally as Trombone Shorty, worried the music would die in the wake of hurricane katrina. I wanted to be able to reach the students of music citywide and have some type of effect on them. Reporter partnering with fellow musicians and Tulane University to found the Trombone Shorty academy, a magnet for aspiring young musicians. In two years more than 100 kids have been immersed in everything from music and the music business to its roots. Maybe in the next 50 years or 30 years what they create these kids now they stick with it, it can be the new classic. Reporter 18yearold Jasmine Batiste stuck with it and won a scholarship to southern university. Its important to me to keep playing because i feel like its my calling. Reporter in mentoring the next generation, Trombone Shorty has learned a thing or two as well about the city he loves. New orleans and the music may be a bit waterproof. I dont think nothing can run us out of here. Reporter now that is something to blow your horn about. Kevin tibbles, nbc news, new orleans. On that note, thats our broadcast for a tuesday evening.
