The sponsoring Go Fast Sports & Beverage says Eric Scott took 21 seconds to cross the Royal Gorge at 75 mph on Monday. It says he didn't use a parachute while flying across the 1,100-foot-deep canyon.
He was wearing a jet pack powered by hydrogen peroxide and developed by Jet Pack International. The company developed it for stunts, promotions and other events for Go Fast.
Both companies are based in Denver and were founded by entrepreneur Troy Widgery.
