Well, win lose or draw, pitch up then rapid loss of altitude sounds like a full on departure from controlled flight to me. That's where it turns from an elegant flying machine to a wet bag of cement. Walks talks and quacks etc.
The whole circus, alpha floor protection et al, is never supposed to go anywhere near that mode of flight for the very reason that it is pretty damn unpleasant, is flight test only and certainly not something you
ever want pax to experience.
What caused it is the question. "there it goes again"
