Mep!!
Plane came in too slow. stalled then wing dropped. Way too low to recover. You can see the plane wallowing before the stall and I bet their stick shakers were going nuts.
They all "died suddenly" of the death. Classic stall..
Yep. it was like they performed a landing flare in mid-air, causing the plane to mush out and go into a wing tip stall. Not enough air speed for the lift needed.
Bollox, the plane was too slow and at too big an angle of attack, the wing tip stalled and it rolled.
