And if it is the fuselage that's 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 they're not holding out hope much longer. they don't believe after all this time that anyone survived that crash. back to you. >> nbc's katy tur in indonesia, thank you. joining me now is former corporate pilot anthony roman. a lot of information that doesn't give us a better picture of what potentially happened to this plane. >> there's still a bit of a mystery. the last air traffic control radar refl...

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 we're considering everything and we certainly don't have everything at our disposal. >> so that ground speed of 63 knots is a net speed. it's not necessarily the actual speed the plane was going. important to note. alistair, if the plane...

With the aircraft. there's two different ways the aircraft could have climbed. that's 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 there's 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 wouldn't be unusual, would it? >> very much so. >> it would feel bad if you're a passenger in the plane. >> it's ...

An hour and you're going the opposite direction, your ate indicator in the aircraft will say i'm going 350 miles an hour but on the ground speed you're only going to be going 150 miles an hour. does that make sense? it's relative to what the wind is doing at any given time so that's why some of these facts don't appear to line up but they really do. >> it's strange, this was a very experienced pilot though right? >> very experienced. >> it seems unlikely he'd do this because it's not the smartest thing to do. >> well he may not have been aware of it. in flight 447 that's what happened. experie...

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? >> it's certainly possible. in fact i've 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 alistair's point on the air speed he's correct the airplane couldn't maintain flight at that speed however, what was...
