World's largest paper airplane flies over desert

World's largest paper airplane flies over desert: "At a length of 45 feet (13.7 meters), a wingspan of 24 feet (7.3 m), and a weight of 800 pounds (363 kg), Arturo’s Desert Eagle is claimed to be the largest paper airplane ever made. Its design was based on that of a much smaller paper airplane, created by 12 year-old Arturo Valdenegro of Tucson, Arizona. Valdenegro was the winner of a contest held by the Pima Air & Space Museum, in which children competed to see whose airplane could fly the farthest. A team of engineers proceeded to recreate his winning plane on a grand scale, and last week managed to fly it after releasing it from a helicopter over the Arizona desert."
