Indonesia Parliament report might be briefly summarised as reported...
pilot fought to keep the plane in the air after it stalled and was nose-diving to the ground.
the aircraft experienced “the same obstacles” (as) on the previous day’s flight from Denpasar to Jakarta but on that occasion the pilot had managed to keep control of the plane
the pilot attempted to offset the (nosedive) action, fighting to keep it in the air
became “increasingly difficult to control the airplane”
the load on the steering wheel became too heavy for the pilot to manually control, and “then the plane drops”
the aircraft crashed into the sea at a speed of more than 400mph.
the 737 had no engine problems
I read somewhere the loads on the control column can become more than one pilot can overcome.
