The Skycycle X-2 was a steam-powered rocket owned by Evel Knievel and flown during his Snake River Canyon jump in Idaho in 1974.
An earlier prototype was designed, named the Skycycle X-1, by Doug Malewicki and retired U.S. Navy engineer Robert Truax. It was tested in November 1973 and dove in the Snake River.[1]
The Skycycle X-2 was designed by Truax,[2] and ridden by Knievel in his attempt to jump the Snake River approximately 1 mile (1.6 km) west of Shoshone Falls near the city of Twin Falls, Idaho, on September 8, 1974.[3][4][5][6][7][8] The parachute deployed during the launch, causing the stunt to fail.[9]
A later analysis showed that a design flaw in a mechanical parachute retention cover that did not properly take base drag into account caused the premature parachute deployment. Following the failed jump, Truax and Knievel blamed each other for the failure. Later, Truax accepted full responsibility for the failure.[10][11]
