Watching camera 5 it was hard to distinguish from the background but it looked like they made a couple of nose down push overs in succession dropping about 10ft at a time before they made the first contact with the runway.
Not sure I have ever seen that technique before.
It may not have been a technique. They may have been pushed down to the runway by turbulence. Aspen is a mountain strip after all.
But I have to admit, I think I can see the tail moving up and down in the attempted flare before the bounce and ugly pushover. Must have been ~ 20 degrees nose down.
Could they have broken something in the controls in the bounce immediately prior that would cause that? Otherwise it had to be a panic response to the high nose bounce attitude.
