And if it is the fuselage thats where they think the majority of the bodies will be. on another note i spoke to a lot of family members today. they said although they have been holding out hope theyre not holding out hope much longer. they dont believe after all this time that anyone survived that crash. back to you. >> nbcs katy tur in indonesia, thank you. joining me now is former corporate pilot anthony roman. a lot of information that doesnt give us a better picture of what potentially happe...

Still very high. with a forward headwind you could show 64 knots with a 200-knot headwind which is what this was the case. it could be actually a relative speed of over 200 miles an hour in which case it could sustain flight, so while these facts and figures can put us in places if we assume a theory in the first place, it makes sense, but we have to make sure were considering everything and we certainly dont have everything at our disposal. >> so that ground speed of 63 knots is a net speed. it...

With the aircraft. theres two different ways the aircraft could have climbed. thats one. the other is a strong updraft, hot air coming up from the bottom coming up from within a thunderstorm can lift an aircraft thousands of feet in just a matter of seconds so theres two possibilities as to why and how it climbed. >> when they talk about steep climb the plane would be going up an angle like this? >> correct, correct, pulling back, flying the aircraft up at a steep angle. >> that wouldnt be unusu...

An hour and youre going the opposite direction, your ate indicator in the aircraft will say im going 350 miles an hour but on the ground speed youre only going to be going 150 miles an hour. does that make sense? its relative to what the wind is doing at any given time so thats why some of these facts dont appear to line up but they really do. >> its strange, this was a very experienced pilot though right? >> very experienced. >> it seems unlikely hed do this because its not the smartest thing t...

Indeed, so the aircraft is only going one way, and that was down. >> but david, these numbers that are talking and that was per minute, pardon me on saying per second, 6,000 to 9,000 feet per minute. the climb, that was the initial part of this data is that possible? >> its certainly possible. in fact ive investigated one accident in which these numbers are almost eerily comparable over colorado on monarch pass in which the aircraft had climbed at least those rates and back to alistairs point on...

Plane, you know find the voice recorders and the cockpits and thats when you start piecing together this whole tragedy. >> thats right. so important. andrew stevens, thank you, from surabaya live for us. i want to get more now on what evidence is telling us so far and what effect the weather could have played in this tragedy. joining me now, cnn aviation analyst david soucie and on the phone we have an aviation analyst, as well as a former pilot. the sydney morning herald reporting now supposedl...

Flying into which would appear on the ground he would be going slow. >> ground speed in and of itself doesnt tell us enough. we need to know more. colonel, what about the incline? this article says that the plane appeared to be climbing at an almost impossibly steep lift. >> well the steep angle which it appeared the plane could have -- another scenario from david is the plane stalled. if the plane was at altitude and then it stalled at that high deck angle or high angle of attack the plane woul...

Than per second. >> yeah. >> an aircraft -- an aircraft at that altitude cant climb at that sort of rate. the only way any rate of climb of that nature could have happened would have been through an updraft in a severe thunderstorm. and even that is you know an extreme figure. the figure that you gave 70 miles an hour, 63 knots, would have been a forward ground speed. thats below the normal flying speed of an airline, it suggests that the aircraft is stalled and was literally falling basically d...

Because the relative air around the airplane as youre going down is what youre measuring with indicated air speed w-the air speed according to the aircraft. if you measure the distance from where it started its descent to the time it ended thats what they are talking about the speed. it went from here to here but at a steep angle its only going that far. so on the ground speed it looks very very low but the air speed which we dont have in this report could be very very high. >> of course thats g...

A very low forward ground speed, but as the other gentleman mentioned in the case a high air speed, in which case the airplane wouldnt have been flyable, but if the airplane goes into the sea, its going to break up. theres no question about that. so you know what were talking about here are the violent winds you get inside a thunderstorm these are vertical winds, upwards and downwards rather than the typical jet stream where you could get 100 or even 200 knots over the pacific. but there were no...
