Local farmer Shu Mansheng starts the engines of his self-designed and homemade flying device before a test flight in front of his house in Dashu village on the outskirts of Wuhan, Hubei province September 21, 2011. The round steel flying device, which cost more than 20,000 yuan ($3,135), is the fifth model made by Shu, a junior middle school graduate. It measures around 5.5 meters (18 feet) in diameter, and is powered by eight motorcycle engines. Shu managed to hover for 10 seconds at about 1 metre (3.3 feet) above ground during a recent test flight. (REUTERS/Stringer)
