Successful Human Powered Helicopter Flight Worth $250,000
A Canadian engineering team became the first to successfully fly a human-powered helicopter, staying airborne for at least 60 seconds. The challenge was established in 1980, known as the "Sikorsky Prize."
According to www.cbsnews.com, "In order to win the Sikorsky prize, an "aircraft using only human power" had to fly for at least 60 seconds, reach a height of at least 9.8 feet (3 meters) and hover over a 32.8-by-32.8 feet (10-by-10 meter) area."
