Concours, what you postulating may be true once the stall was completely developed - my point is that it should never have gotten that far.
Ask any first year Aero student this question:
"You're at a stable 35k cruise, then pull full nose up and leave it there, what will happen?"
They'll respond along the line of "you'll climb - trading airspeed for altitude".
And if you keep the stick full back, what then?
"Why would you do that, you'll stall!"
What I can't understand (and can't forgive) is why Bonin didn't know that basic fact...
