I know it is not relevant to the discussion simply because the airplane is as it is, but if it had been a normal control column everyone would have seen the PF holding the stick right back in his lap, and nobody would have needed any flight instruments to see how very wrong that was.
No pilot would have tried to fly that way in the first place, and I would say that the design of the side stick lends itself to being misused in that manner.
What has/is being done to prevent a reoccurrence?
I have an aversion to robot airplanes and auto flight systems I guess. I will use an autopilot and am happy to do an auto land, but if I ever got to the stage where I could not do everything the autopilot could do, I would give up flying. Many of the pilots I fly with have never learned how to really fly an airplane, which is a pity and is a threat to the overall safety of aviation, and not just airline aviation.
This accident, I fear, will be repeated. And two B757 accidents with a loss of control by the pilot show that it is not an Airbus/Boeing, control column/sidestick problem but a problem with flying skills.
