DENVER - A DAREDEVIL hopes to propel himself across a southern Colorado canyon using a jet pack powered by hydrogen peroxide.

Mr Eric Scott tells the Rocky Mountain News for a story on Saturday that he's never travelled as far as he wants to on Monday: 457m.

The Royal Gorge is more than 335m deep. A bridge spanning it was the site of a deadly stunt in 2003 when a parachute jumper miscalculated and fell.

Mr 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 20sec. The new one can go for more than 30sec at faster than 70 mph. -- AP
