I am one to fail often, sometimes causing big adrenaline rushes in my coach/team, sometimes not, but I've miraculously never hurt myself. There are the usual fails, such as front tucks with my head almost kissing the ground, me falling on my butt during warmup simply by doing round offs with powerful snap downs, or me doing some of the nastiest looking round off-back handsprings (still do, on my off days, which are every other day, basically).
The cooler ones that come to mind include my first attempt at a round off-back handspring on a trampoline - after the round off, my mind went blank and I threw myself back in a freaky way, enough to freeze everyone that was looking at me. I managed to fall in a safe position, I don't really know how. My coach might have done some magic trick, but I didn't even notice. One of my first attempts at a round off-back tuck in the air track was identical, except that this time I was a bit too high for my coach to be able to do much (and I'm big, anyway). While he waited for me to come down, I did manage to see the floor while still being completely upside down and place my arms in a way that allowed me to push myself out of danger or something. One time, I also fell off the side of the tumble track after a misaligned back handspring and I was also close to landing on my head during a back handspring because I didn't scoop enough, went way up, lost track of where I was in the air and opened my arms too wide without even noticing. Apparently, I looked like Jesus Christ happily flying away or praying not to die. This was really a stupid moment, because I already knew how to (and always did) handle high rebounds; I just ride them as if I wanted to do a whip or a layout.
No injuries to share, fortunately. I rarely bail out of anything (good thing), but I lose focus far more easily than I should (terrible). My huge inconsistency is a fail in and of itself, lol.
