But beyond that, you. >> caller: really can't tell. the idea that the plane did a dramatic climb, radar notoriously is unreliable for recording that kind of behavior in a plane. so we just don't know. but we're going to find out. >> even that radar that we're talking about, that the sunday morning herald repeated? >> if it was mode s, still, it's an extraordinary climb. >> speak to that a little bit, also because the information -- this was information that was leaked that was given to the sydney morning herald. it talks about ground speed but we don't have the indicated air speed. the ground ...

The mode s transponder gives more information but there's a time delay so we really don't know what that was -- what that ground speed was -- or that air speed on the radar was all about. there's a difference like you indicated, between what the airplane senses and the ground speed. so it's all subject to possible dis discrepancies. the climb seems extraordinary. they could have gone through a thunderstorm that causes a lot of updrafts in addition to downdrafts. so weather does seem to be related but, once again, we can't rule out anything. and i think it's important to determine flight breaku...

Played a big role. >> it does. it does. just the climbing wouldn't answer that entire picture. we're using that information. if it was a combination of climbing and rapidly rising air that's when we would have some serious, serious turbulence that could damage the aircraft. >> i want to add in one more factor. there's another fact out there. the sidney herald obtained so i radar data and see this excessive climb or excessive speed in climbing. but in contrast the article said the plane traveled as incredible low rates of descent. it says as baffling was the extremely low ground speed which was...

That seems a little implausible to me. 105 knots that was indicated would have been ground speed. airplane sense, airspeed in the air relative to what's going on over the wing that steep rate of climb seems a little unlikely. there are updrafts in a thunderstorm. there are also downdrafts. that rate is certainly possible. it doesn't indicate to me that there was a 20,000-hour skilled pilot at the controls. if that was happening in my airplane instinctively we would disconnect the auto pilot and attempt to fly our airplane. that data just doesn't seem -- >> when you talk about an updraft, what ...

The way it goes down is bordering on the edge of logic. this analyst was puzzled by the extremely low ground speed he saw, saying the plane was descending at the same speed as a car on the highway. cnn doesn't have this information independent right now. david soucie if it's true if it's accurate what does it tell you about what happened here? >> well it's hard to say because of the fact that they said ground speed. ground speed is just simply that, how fast you're traveling over the ground. if you have a 200 knot head wind you'll be traveling in an airplane at 264 knots. on the ground speed, ...
