The PNF who retracted the leading-edge flaps ("droops") prematurely was very new, and knew that the next thing he would hear from the dour old captain would be his command for that. The captain was having a heart attack...
My recollection of that accident is somewhat different. From what I read the captain was in a foul mood after being involved in a trade union altercation in the crew room prior to the flight.
The two minions on the flight deck were understandably frightened of his martinet personality. While climbing steeply as part of the noise abatement procedure in cloud, the new first officer inadvertently selected the droop lever to up instead of the flap lever to the called for setting.
At the low speed the aircraft was flying at during the noise abatement climb, a stall happened. I don't recall the heart attack theory or if the captain did suffer a heart attack at the crucial second.
Or whether the autopsy found he was in serious danger of a heart attack.
In any case, realising his F/O had whipped the droop lever up at low flying speed and relatively low altitude would be enough to scare anyone into a heart attack!
