^ Any successful landing is one you can walk away from.
Only actually had one 'incident' myself - my first flight in a type unfamiliar to me (a Discus). I found on the downwind leg that my arms were not long enough to push the undercarriage lever far enough forward to lower and lock the gear. (needed about another half inch of reach) My harness was too tight and I didnt have the time to release it (which would also have been fcuking stupid at 400 ft and about to make the final turn), so I deliberately landed wheels up.
(Fcuking expensive night in the club bar that one
