On May 14, 2008 (April 10, 2008 in the lunar calendar), the Swiss "Rocket Man" flew over the Alps. Former Swiss fighter pilot Rossi, who spent five years building and perfecting the power wing suit, jumped off a small plane yesterday wearing it. When he jumped from the 2250-meter plane, he unfolded a 3-meter-long power wing, which was tied behind him. After transitioning from free fall to taxiing, he fired four engines, which accelerated his flight speed to 304 kilometers per hour. After climbing to 780 meters, he dove towards the ground again, leaving a string of special effects smoke behind him. Rossi, 48, said that after completing the feat of flying over the Alps, he plans to fly over the English Channel later this year, and he also plans to fly over the Grand Canyon in the United States. In order to complete these plans, he had to install stronger engines to gain greater freedom. The current four aircraft engines provide 800 pounds of thrust, enough to allow the 1101-pound foldable wings and Rossi to climb at 60 meters per minute. Rossi said: "In terms of physical strength, it definitely does not constitute pressure. It's like riding on a motorcycle, but I have to relax because if I feel any tension, I start shaking. If something goes wrong, I can press the yellow handle to drop the power wings and open the backup parachute."
