according to airline ratings.com which obtained this screen grab this indicates that 8501 stalled, moving about 100 miles too slowly for such a high altitude. this website s editor-in-chief spoke with cnn. listen. it s a wing stall not an engine stall. i have to clarify that. it s a little bit confusing to the viewers when you talk about a stall, you think about your car stalling on the freeway. this is an earaerodynamic stall. elter because there s not enough speed or the plane is too sharp of an angle and the air on top of the wing is disturbed and no longer giving lift. let s turn to david soucie. david, what do you think about this theory? is it possible the wing stall yeah definitely is at this point. if you re climbing at that rate at that altitude and you re trying to go through that
tell him what position the aircraft is. flight 447 in that accident the air speed indicators were not working and he no idea what speed he was. whether he was under speeding or designee didn t know. sometimes you re in limbo up in the air. that s right. whereas in this case we don t know. your point was good we don t know what happened. people say why your speculating. why are you doing this? it s horrible for families. the reason we speculate is to assist in the finding of the aircraft. where is the aircraft. if it s a power on stall a deep stall like this one it could go in literally any direction after that stall. a wing stall means i want broadens the area you have to look? actually an air stall. it s the stall of the air over the top of the wing that really causes this and so after that the aircraft trying to get that air speed could go right, could go left could turn around. if it was a different kind of stall it would have continued in
transitional period if you don t have enough air speed that s a bad position to be in. it s called coffin corner. where you stalled and no recovery. we just want to emphasize we don t know if that s exactly what happened here. but if it were a wing stall that happened what causes that? if you remember as a kid and i used to do this all the time driving down the highway sticking your handout the window. as long as your hand is going in this direction you re in. if you go like this the wind is very strong against you and very difficult to control where your hand is in that wind. this is very similar to that. the wing when in its at the right flight altitude the air is going over there smoothly. when the angle of the attack goes against the wind to such an area where the air behind it starts to burble and breaks that suction, now you take that amount of air you feel on this
video is actually first you see the left wing go down. it sort of rocks left. and then the right-wing goes down. and you can see then the nose follows down to impact. and what this appears to be is basically the airplane is stalling. on a swept wing jet like this, you ll tend to have the wing stall at the tips. they lose lift at the tips and tend to bring the nose further up. so it appears that we have a stall now. we don t know yet why they stalled. there s a couple of things that could be. first off in a military base like this when you re in hostile territory, it s normal procedure to do a very steep climb to get away from surface-to-air missiles. so they would be climbing steeper than you would have in a normal departure. that should have been fine. it could have been that the trim settings were incorrect so the nose went up higher than
and then as you watch it, it kind of appears to stall. and then you see the nose pull up. the tail appears to drop. this is all to a lay person s eye. did something go wrong here or not? well, so what we see in the video is actually first you see the left wing go down. it sort of rocks left. and then the right-wing goes down. and you can see then the nose follows down to impact. and what this appears to be is basically the airplane is stalling. on a swept wing jet like this, you ll tend to have the wing stall at the tips. they lose lift at the tips and tend to bring the nose further up. so it appears that we have a stall now.
