An AC crash impact in a "stall pose" means TAIL FIRST (as a tail strike in TO or landing).
This is "in the moment of impact".
IF an AC begins a stall -say at FL300- and THEN it spins or flat spin or whatever makes and the impact is in another position, then it isn't a crash in "stall pose".
Now i'm getting confused. I'll admit that I have read the words "wet wing" but I have never read the words "stall pose" in an accident description.
Are you saying that even though the pilot couldn't lift the nose using aerodynamic controls as it flew into the ground that it wasn't stalled at the time because the nose was pointing down?
