Bex, Switzerland ? A Swiss pilot strapped on a jet-powered wing and leaped from a plane Wednesday for the first public demonstration of the homemade device, turning figure eights and soaring high above the Alps.

Yves Rossy’s performance in front of the world press capped five years of training and many more years of dreaming.

“This flight was absolutely excellent,” the former fighter pilot and extreme sports enthusiast said after touching down on an airfield near the eastern shore of Lake Geneva.

After jumping at 7,500 feet, Rossy, 48, triggered four jet turbines on his wings and accelerated to 186 miles per hour, about 65 miles per hour faster than the typical falling skydiver. A plane that flew at some distance beside him measured his speed.

The crowd on the mountaintop below gasped and cheered.

Rossy’s mother, who was among the spectators, told journalists she felt no fear. “He knows what he’s doing,” Paule Rossy said of her son, who now flies commercial planes for Swiss airlines.

Steering with his body, Rossy dived, turned and soared again, performing what appeared to be effortless loops from one side of the Rhone valley to the other. At times he rose 2,600 feet before descending again.

Rossy said after Wednesday’s five-minute flight, he is ready now for a bigger challenge: crossing the English Channel this year.

The stunt, to be shown on live television, will test his flying machine to the limit. Rossy said he plans to practice the 22-mile trip by flying between two hot-air balloons.
