IF, re: “ . . . pull back as hard as I like to get maximum climb . . .”

You seem to think he did this from the outset. He didn’t. If you look at the “stirring mayonnaise” chart,

[see:
http://www.pprune.org/tech-log/46839...ml#post6819601 ]

his pitch up inputs were neither full nor consistent at that time. Some have postulated that the stick back was inadvertent while he was using (too) large movements in roll. (PNF was telling him to make more gentle movements.)

It was after getting roll under control that he went to full stick back, AIUI.

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.
