Evel Knievel's iconic launch, Take II.

Eddie Braun, fueled by the memory of the late daredevil, plans to strap into a steam-powered rocket cycle on Sept. 17 for his most death-defying role yet: Replicating a launch over the Snake River Canyon in Idaho that almost cost Knievel his life four decades ago.

Braun named his rocket "Evel Spirit " after his boyhood hero. It's nearly identical to the model Knievel used for his failed canyon attempt on Sept. 8, 1974. Braun wants to prove Knievel could've made it had his parachute not prematurely deployed.

Along for the ride in this endeavor are two sons eager to complete the legacies of their fathers: Kelly Knievel, who was present the day of the crash, and rocket designer Scott Truax, whose dad constructed the original rocket cycle for Knievel.

Ready, set, and (gulp) launch.

"Evel took off on one side of the canyon in 1974. I'm hoping his spirit lands on the other side of the canyon in 2016," said the 54-year-old Braun, who says he completed the necessary paperwork and will launch a few miles away from Knievel's original site that's near Twin Falls, Idaho. "How many people get to fulfill the dreams of their hero? It's kind of like touching Superman's cape."
