I agree the video in post 155 shows a classic high-G, high-speed wing stall (wing drop, and the whole aircraft sinks behind the tree).
But by that moment, the aircraft was almost certainly going to hit the ground, regardless. The "accident" (whatever it was), that put the aircraft in a position where it must hit the ground one way or another, began much earlier in the maneuver. The stall only changed the impact point by a few yards.
The stall may - emphasize "may" - even have been the result of a well-intentioned pull on the controls to try and clear the people-filled highway, and crash in open ground beyond. But physics and aerodynamics are unforgiving...
