Evel Knievel sits in his steam-powered "rocket cycle" before his September 8, 1974, attempt to jump the Snake River Canyon near Twin Falls, Idaho. (Note his lucky rabbit's foot.) Forty-two years later, Hollywood stuntman Eddie Braun plans to try the same jump, in a replica of Knievel's aircraft, to honor his daredevil hero. ap

Their first prototype, the Skycycle X-1, plummeted into the Snake River. Knievel's engineers built subsequent models to be less like a motorcycle and more like a rocket. courtesy knievel family

A master showman and self-promoter, Knievel built enormous anticipation for the jump. He developed a working relationship with ABC Sports, which often televised his jumps -- and slow-motion footage of his famous crashes -- although the network balked at his price for the Snake River stunt. Knievel eventually hired boxing promoter Bob Arum to broadcast the jump on closed-circuit television and in movie theaters. courtesy knievel family

A parachute on Knievel's Skycycle opened prematurely at launch, hindering his ascent. Winds dragged his craft backward and he ended up in the canyon, where he landed only a few feet from the river. If he had landed in the water, Knievel, who was strapped into the Skycycle, almost certainly would have drowned. He suffered only minor injuries. ap
Although it failed, the Snake River Canyon jump added to Knievel's already considerable legend. He broke his pelvis while attempting his next jump, eight months later at London's Wembley Stadium, and attempted six more public jumps before retiring in 1980. He died in 2007. "My dad jumped 275 times, and it's not the 260 times he made it that made him famous," his son Kelly Knievel says. "It's the 15 times he crashed." courtesy knievel family
