Yves Rossy, known as the 'Fusion Man,' flies with a jet-powered single wing over the Alps in Bex, Switzerland, Wednesday, May 14, 2008. Some people go fishing on their day off. Yves Rossy likes to jump out of a small plane with a pair of jet-powered wings and perform figure eights above the Swiss Alps. The revolutionary human flying machine comes after five years of training and many more years of dreaming. (AP Photo/Anja Niedringhaus)
