For instance, both PF and PNF may not have been able to remove their hands from the control yokes due to the forces required to have control of the yoke. I don't know. I do know that the forces required for pushing the yoke forward are significantly less than pulling the yoke back. With the aircraft achieving the attitudes and velocities it did I am not sure what forces would be required.
Hval...
I think you have the big picture.
The crew was likely a bit busy to stop and ponder the various aerodynamic forces and nifty stall recovery QRH checklists while strapped to a very heavy airplane very close to the ground while it was pitching to an angle that likely none of them had ever experienced before.
But that's just my opinion. I could be wrong.
