This is Christian Kellner, a motorcycle racer in the 2002 World Supersport Championship. Nobody is going to argue that Kellner himself is somehow unskilled: He spends his working day reacting to thousands of life and death problems at roughly 1/4 the speed of sound. And I'm certainly not implying that he doesn't have the will or wherewithal to guide himself safely through a tough situation: The man gently places his crotch on earthbound missiles for a living. He's basically a giant throbbing pair of testicles with a funny little helmet on. But when this happened ...
... skill, fortitude and reflex all went vomiting out onto the pavement. The accident happens so fast that you don't even really have time to see it, so here's what went down: Coming around that turn at an objectively ridiculous speed, Kellner's oil line ruptures, spewing a huge slick directly beneath his own rear tire. Kellner of course promptly goes hurtling into a wall, which is pretty much your only viable response to anything on a motorcycle. Now, that impact on its own is quite enough to turn a human being into a nice pudding, but it's not all that remarkable in motorcycle racing. What is remarkable is that the riders behind Kellner, just milliseconds back, also hit the slick and simultaneously spin out, effectively sending three 400-pound metal bullets flying right at Kellner's already deliciously tenderized body.
