Once they were deep into the incident the warning worked bass ackwards; they reduced AoA, speed increased beyond 60KIAS, the stall warning sounded, they pulled back again, speed reduced, and the stall warning stopped.
This is possibly far more significant than the reports suggest.
The stall warning was clearly misbehaving so they would have ignored it and concentrated on the unwinding altimeter and the overspeed warnings.
Looks like we are in a steep dive - pull up before the wings come off.
Yes, they made the wrong decisions but they were faced with multiple conflicting bogus sources of information.
It would be interesting to put a few dozen pilots into the simulator and present them with the same symptoms of bogosity overload. Would you have got it right ?.
There but for the grace ......
