[Sambolin:] Here are some of the stories that we're following. Almost 40 years after the war with Vietnam, there was a dramatic exchange this week in Hanoi. Defense Secretary Leon Panetta received personal letters taken from an American army sergeant killed in action in 1966. In exchange, Panetta returned the diary of a Vietnamese soldier killed that same year. Mitt Romney's favorable ratings are up, but he still trails President Obama in popularity. In a new CNNORC poll, 56 percent of Americans say they have a favorable opinion of the president. That's compared to 48 percent who have a positive view of Romney. Forty-two percent have an unfavorable opinion of both. And FaceBook is considering letting younger children onto its website. That is right. Kids younger than 13 may soon be allowed to log on to the social media site with the rest of us, with, of course, parental supervision. Some say FaceBook is just trying to profit off our children. But according to a study from the online journal "First Monday," a lot of kids are already on FaceBook. 69 percent of 13-year- olds and 55 percent of 12-year-olds. So check their accounts. Nigerian officials say an American was piloting the plane that crashed yesterday in Lagos and the State Department confirms that U.S. citizens were on board. Let's go live now to Vladimir Duthiers in Lagos. Do we have any updated numbers on that fatal flight, including how many Americans were on board?
[Vladimir Duthiers, Cnn Correspondent:] Zoraida, just recently we heard from the State Department and they have confirmed that there were American citizens on board this flight. However, they have not given us a number. What we did confirm earlier this morning was that the pilot of this aircraft was an American citizen. We do know that this airplane was rolled off the assembly line in 1990 for Alaska Airways. Donna Air in Nigeria purchased that aircraft several years ago, and the airline itself has only been in existence for about four and a half years. As far as other citizens, most of the passengers were Nigerian although we're told there were also some Chinese citizens, some Indians, and some Lebanese Zoraida?
[Sambolin:] Vladimir, what are airline officials saying about the minutes before the plane went down? Do we have any information?
[Duthiers:] So the chief pilot, I spoke to him earlier this morning. He said that right before the plane was about 11 miles away from the runway when the pilot radioed in for an emergency. He said there was some kind of emergency on the aircraft. That was the last they heard from him. Witnesses on the ground say the plane was coming in what they call low and slow. The plane hit tail first into a densely populated neighborhood. Some of the homes are so close together, you could actually just stand in between the two homes and touch both of them at the same time. So far, we don't have a number of casualties on the ground yet, but it's a miracle that many more people were not killed. We were literally standing just across the street from the crash site in a home that was standing, you know, perfectly rock solid, talking to some of the people that survived the crash, and essentially they were saying they were very, very lucky because the plane seemed to only hit about three buildings in this neighborhood where houses are literally packed on top of each other Zoraida?
[Sambolin:] I know that it's really difficulty at this stage of the game. We are talking earlier about perhaps 10 people dead on the ground. What do we know about the search operation as it continues? As we were watching this fire, which is totally out of control in that densely populated area that you had mentioned, it was a really difficult fire to put out.
[Duthiers:] Yes. When we arrived on the scene last night, it was pandemonium, chaotic. There were no lights, and it's pitch dark normally in Lagos. Very few homes have running electricity. Everybody powers up with a generator. We get out there, it's pitch dark. There are a few fire brigades trying to put some water on there. Lagos, for a city of almost 16 million people, has very few fire brigades. There were some people using pails of water to try to put the fire out. Today, a much different scenario. The first responders have blocked off, cordoned off the area around the crash site. What we saw was a smooth operation going. When we spoke to the head of the agencies that were responding to the crash, they had already pulled 53 bodies from the wreckage. They were pulling many more out when we were there. Much different scenario from what we witnessed last night.
[Sambolin:] All right. Vladimir Duthiers, live for us in Lagos for us. Thank you very much for that report. Hit men, kidnappers, and roaming gangs it's just another night inside one of Pakistan's fastest-growing cities. We'll tell you why the violence there matters to us here.
