Not many have seen this video until now. The commentator is Ross Sully of Canada.
It shows my crash in an F1 race in Troy, Ohio in 1990. I was trying to take a different line up the transition from the river when it caught air and cartwheeled. It doesn't look like a big deal, but replay it in slow motion and you'll see it differently.
When the nose hit, the handlebar grip came off and I was a rag doll into the lift engine. I tore off the gas tank with my face (and I was wearing a full face helmet too.)
The result: 70 stitches in my upper lip (clean cut up to my nose), 20 stitches in my tongue (split like a snake); knocked out my front tooth, and a hole in my leg.
At first I was dazed and was concerned about getting hit by the craft behind me, but blood went everywhere when I stood up and I thought " forget the hovercraft"!
