Going back to flying basics if we found ourselves in a runaway trim or unusual attitude putting your airliner in a high nose up pitch attitude rolling into a 60 degree bank to drop the nose back down to the horizon was part of the recovery if necessary. I know the Airbus 320 has a restricted bank angle so the pilot cannot not exceed that bank. I never had to fly an airplane that wouldn't let me do what the computer disagreed with so don't know what these pilots were dealing with. They were all highly qualified pilots so must have done all they could with what they had to work with.
