No offense taken. I meant that if I start researching it again I’ll be up for 5 hours because of the personal ties to it.
My recollection in researching this a decade ago was that the cold weather made the behavior of the rudder change (my term was invert, maybe that’s not accurate), and pilots were trying to pull up, but in fact putting the plane deeper into a nosedive. Some 25 seconds later they hit the ground at some 300-400 MPH and vaporized.
The only way to have saved the plane would have been to dump the hydraulics and/or switch to a manual fly by wire mode, neither of which were a logici thing to do in the 15 seconds they had to save the flight.
I’ve only flown for 20 hours in a Cessna so sorry if my terminology isn’t perfect!

The rudder controls yaw, not pitch. The rudder controls did invert: the pilot tries to turn slightly left, the plane turns right, so the pilot naturally tries turning harder left until the rudder is in the full right position, and they're in an uncoordinated turn. The wing on the inside of the turn starts to drop significantly or even stalls. The plane is then sideways and in a dive, and on top of that, the rudder is all the way over in the direction that makes the dive steeper. The planes quickly rolled over on their sides and went into steep dives. My understanding is that a big break in the case came when a pilot figured out what was going on and successfully landed a plane with reversed rudder controls.
