Really appreciate you being with us today. thank you. cnn aviation correspondent pete monteen also with us. as we look at the videos posted of this crash, these moments, as i have heard a number of times a plane at 28,000 feet does not just fall out of the sky. what do you see in these videos that have been posted? reporter: so many people are looking at these videos. in fact, a former managing director of the ntsb tells me an airplane like this does not come out of the sky like this without some sort of help. look at the video of this airplane essentially free falling here. and you can see what appears to me to be vaporized fuel trailing behind it. this is what s really interesting, and when you take it a layer further and if you slow the video down and bring up a still here, this is a little blurry, but this is the airplane, you can siee the fuselage, one wing here. what is missing is the other wing.
