About that animation
The animation implies a stall break at some 45 degrees AoA, which IMHO can only happen if there was substantial engine thrust. Yet those few witness reports that mention engine sounds seem to place the sounds at very close to when the aircraft hit the ground. Had the engines been screaming at high power at that altitude, presumably many more witnesses would have noticed.
I have yet to see a witness report mentioning the nose pointing downwards from the horizontal at any time, as the animation implies.
Finally, the pullout close to the ground looks like a fairly high-G maneuver. Again, no witness reports that mention that kind of push-me-into-the-seat sensations.
Admittedly I haven't read the witness accounts very systematically, but my guess is that the events looked less dramatical than the animation suggests. Correct me if I've missed something. Well, anyway, we'll see soon.
