> But why keep climbing when something is wrong? Two possible reasons in this case. 1) Bonin might not have understood he was in full manual control, and that the computer was no longer restricting his pitch up command to the maximum advisable pitch. 2) The stall warning was intermittent on the way down, because it turns off below a certain air speed. Of course, low air speed contributes to stalling. They were stalling the whole time, but ironically as they started to gain air speed (a good thing) the stall warning would kick in because it was no longer below the lower limit for a stall warning. Also there's the ever present reason of panic, brain-lock, confusion, etc.
