I flew this airplane for a number of years and it can be a real handful to land. There is more 'info' on landing technique than on any other aircraft I've ever flown. If you don't get it exactly right the nose wants to come down rather violently, causing a natural tendency to overcontrol and the nose then pitches up severely. (Part of it is due to where the CG is in relation to the main gear) Add strong gusty crosswinds and this beast can put your heart in your mouth. It looks like there was an attempt to recover from that first overreaction and then the nose hits hard-- after that all bets are off. I noticed that the nosegear had not sheared off from 1 of the pix, so that 'bounce/pitchover' might have happened here at the wrong time.
