Thorough and careful analysis to determine who is on that cockpit voice recorder and what are the sounds. because remember, the recording is for two hours. so its possible they might be hearing the pilots sitting at the gate, they might hear maintenance people in the cockpit, et cetera. every time the flip -- a switch is flipped in the cockpit, that kind of thing, they need to understand what are all those sounds. its a very thorough audio type of analysis that goes on. this could take weeks, ac...

Common explanation for that is that somehow this crew was incapacitated. >> right away? >> incapacitated, you know, so that points to the possibility of decompression of these pilots, every simulator session trained for that emergency, they have quick oxygen masks, they should be able to put them on in five seconds, at that altitude they have 30 seconds of useful consciousness. its very difficult to explain. we have great authority. this mystery will be solved. >> talk, it happened when they rea...

Pilots trying to get the plane down because of some incapacity tating or critical event on board. we dont know what happened because there were no distress calls or mayday calls or nothing xgt but were left to assume that something very serious happened because they were trying to get the plane down so quickly. heres the other thing thats per plexing. if you have a decompression event, if you lose oxygen in the cabin, generally you try toe get the plane down to 10,000 feet so people can breathe....
