@ChrisN Nobody knows what he thought or why, but one possibility is that after getting roll sorted, and the nose had started rising, with whatever alert noises were going off, he became confused; could not believe speeds, started to disbelieve some or all other indications, talked about crazy speeds, ended up stalled but ignoring the stall warning, had huge cockpit noise, (noted by somebody who has heard the CVR, it was reported) and thought, at least at times, that he had overspeed. So maybe he was pulling the nose up to try to slow down. Remember, at one stage he tried to use the airbrakes too, until PNF stopped him.
He actually deployed the airbrakes, at 2:12:04. Three seconds later, PNF said,
at 2:12:07 "No, above all do not extend...." the rest of the sentence is not quoted, if it exists. Spoilers are deployed, not extended. Was PF reaching for FLAP? The "crazy speed" comment comes in conjunction with the spoilers deployed.....PNF has the most time in the 330, and my guess is he would not 'extend' the spoilers, he would "deploy" them.
At 2:10:10.4,
"STALL/STALL". just six tenths of a second later (2:10:11) the PNF: "What is that?" I propose PNF is not rhetorically commenting re: "STALL", he certainly knows what it is, but may be remarking on what caused the AoA to provoke the Warning, the extreme airstream noise that filled the cockpit. A robust turbulence that jiggered the vanes, and caused the Vanes to read correctly, but transiently....STALL/STALL.
