Evel Knieval's Skycycle

Evel Knievel was a stuntman's stuntman. This year marks the 35th anniversary of his Wembley Stadium jump in London, when he revved his Harley and flew over 13 buses. Or tried to. He crashed, broke his back, and told the 90,000 fans there he was done with stunts. The vow didn't last long.

Milwaukee's Harley-Davidson Museum pays homage to Evel with an exhibit from July 10 to Sept 6. See the half-motorcycle, half-rocket “Skycycle” Evel used to leap the Snake River Canyon, along with his red, white and blue leathers and other daredevil memorabilia.

So how many bones did Evel break jumping buses, canyons and shark-filled tanks over the years? Most report say 56, though some estimates go as high as 100.
