問題詳情：
A Canadian university student has done what Leonardo daVinci(達·*奇)had only dreamt of: Piloting a humanpowered“ wing－flapping” plane! Called an ornithopter, and the inspiration for modern－day helicopters, the machine was first sketched by Leonardo da Vinci way back in 1485 and never actually built.
Todd Reichert, an engineering student at the University of Toronto，made history by carrying out the flight in his ornithopter—named Snowbird—for 19.3 seconds and covering 475.72 feet. Snowbird is made from carbon fiber，balsa wood and foam. The 92. 59 pounds vehicle maintained an average speed of 15.91 miles per hour.
Todd and his plane made the accomplishment on August 2,2010, at the Great Lakes Gliding Clum in Tottenham, Ontario. The crew kept the achievement quiet for nearly two months to get the data finalized. Todd and some 30 other students had been working on the plane for 4 years.
Todd endured a year－long exercise program in which he lost 18 lbs，to prepare for the flight. Because the plane has a wingspan of 104 feet—which is comparable to that of a Boeing 737—the pilot had to pedal with his legs all while pulling on the wings to flap at the same time. And he had to do it fast enough to fly!
“Our original goal was to complete this sort of original aeronautical dream to fly like a bird，”said the 28yearold Reichert yesterday. “The idea was to fly under your own power by flapping your wings.”
The flight, witnessed by the Federation Aeronautique International, is the first officially confirmed flight in an ornithopter.
“Thousands of people have tried to do this for hundreds of years ，”said Reichert. “To be honest, I don't think it's really set in yet that I'm the one who has been successful. I was pushing with everything I had. When I finally let go and landed，I was hit with great excitement. It was pretty wild.”
I bet it was, Todd !
