Many posts discuss the continuous back stick, but nobody replied to my earlier thread re the sustained (30s) full deflection roll input.
I find this very significant - but puzzling - for a number of reasons:
1. I can only suppose that it was in response to an opposite bank, caused by turbulence => the PF was following the AI in roll; why not also in pitch?
2. 30s is an age to hold in a roll demand - an absolute age. If the aircraft wasn't responding (which one supposes it can't have been) then this would to most of us must again re-inforce the conclusion of stalled flight and certainly eliminate a high speed dive.
To me this can only point to extreme disorientation/sensory deception and refusal to believe the instruments. As has been noted before, a/c have been lost due to e.g. a single AH failure; the level of failure here was more serious, was in IMC at night...
