As I read that report with tears in my eyes all I can think of is "why?" Why in (censored) did Hal decide the plane had stalled falling from 270 kts to 60kts in less than a minute. That's acceleration that would have shredded the plane. Hal should have disengaged COMPLETELY rather than force the trim ever upwards to try to maintain altitude. It's as if Hal forgot the inertial system was still there and still functional.
JD-EE: Normally I find your comments/assessment rational, but in this case I feel you are way off. Hal did not trim the airplane, the pilot input CAUSED the trim, no other reason than hauling on the joystick. Pitch-up commands for the majority of the ride down to doom.
