Having taught out of control flight in high performance aircraft I can tell you we never taught that. It’s also not taught in current airline simulator training. It is not what Boeing puts out. The last thing you want with trim stuck or running nose down is excessive speed. You control that with thrust. Again it’s called piloting. Had they reduce thrust and kept the speed back below 250 they would not have hit the ground at all. Control forces would have been much lighter. You have to establish the aircraft in a regime where it is controllable. Max thrust is the worst thing you could do in a nose down trim situation.
