A daredevil hopes to propel himself across a southern Colorado canyon using a jet pack powered by hydrogen peroxide.
Eric Scott tells the Rocky Mountain News for a story Saturday that he's never traveled as far as he wants to on Monday: 1,500 feet.
The Royal Gorge is more than 1,100 feet deep. A bridge spanning it was the site of a deadly stunt in 2003 when a parachute jumper miscalculated and fell.
Scott works for Denver-based Jet P.I. The company developed a jet pack for stunts and promotions that is based on one developed in the 1960s for the military.
The original one could fly for only about 20 seconds. The new one can go for more than 30 seconds at faster than 70 mph.
