javadreaming is quite right
even when practicing stalls in simulator (incipient ) and one goes to firewall power/thrust on the engines, the nose up tendency is easily overcome by the control yoke
I cannot see this crash happening for any competent crew, even if the capt had become incapacitated.
did he go around and misjudge his pitch attitude leading to low airspeed and then a stall?
was there any stick shaker sounds on the tape?
did one of the pilots retract all flaps/leading edge devices without the knowledge of the other pilot?
crazy
