Evel Knievel jumps thirteen cars at the 5,600 seat State Fairgrounds Coliseum in Detroit, Michigan.
Evel successfully clears the thirteen cars but, he also successfully clears the landing ramp and crashes into the Coliseum's newly erected safety wall and breaks his collarbone.
Three weeks earlier, in San Francisco, he broke his ankle and bruised a few ribs attempting to jump fifteen cars. But, the show must go on...
Knievel began his snake/barrel/bail/motorcycle/car/bus/canyon jumping career on a 350cc Honda, in 1966 he did two jumps on a Norton Atlas, from March 9, 1967 until October 1968 he used a Triumph Bonneville, April 1969 to August of 1970 jumps were performed on a Laverda American Eagle 750cc and then, the bike he's best known for, a Harley-Davidson XR-750 from December 1970 until he called it quits in 1977.
