Human Factors
Were both pilots seated properly, restrained correctly? A/P to that height seems unusual, was this addressed? B/A SOP? To now, there isn't enough incontrovertible evidence from FDR, CVR to help the cockpit data along very far. 108 knots can't have been acquired with a functional A/P. Nor could it have been allowed by hand, absent ongoing low thrust. The A/P would not have allowed a Stall; Belly on beats nose in, yeh?. Stall is not a result any pilot would choose purposely, choosing it over belly in. Was the AOA (high) a result of the temporary power surge? Any noise heard on the ground that was unusual? Pop. scraping of metal, changing noise levels?
