The flight itself went off without a hitch once Rossy was allowed to get underway. Leaping from a helicopter about 8,000 feet above the canyon floor, Rossy picked up speed and fired up his jet-wing, which he steers using his body as a kind of rudder/aileron. Four small jet motors provide him with enough speed and lift to sustain flight, this particular one lasting a full eight minutes. During the demonstration Rossy hit speeds of 190 miles per hour before powering down his engines and parachuting safely to the canyon floor.
