you are right about the gust lock on system on this particular type of airplane.
i would also say that if the rear seat was wrapped around the stick the FRONT stick would also be full aft. I’m thinking he would have seen that.
I’m thinking that perhaps he left the elevator pitch trim in the full nose up setting- perhaps from the previous landing?
With the elevator trim in the full aft position, the nose would pitch off the ground very rapidly as we saw in the video.
Also, I thought perhaps he inputted some nose-up trim and then perhaps it ran away full nose up deflection.
What throws the trim theory in question though is that there was seemingly no nose down elevator input to at least try to overcome the severe pitch up.
