Way back in 1980 the American Helicopter Society (AHS) challenge man kind to create a human-powered helicopter that can stay at least 10 feet in the air for at least 60 seconds. The prize? $250,000. 33 years later a team named AeroVelo has finally claimed the prize with their absolutely massive four-rotor helicopter called Atlas. You have to see the video to believe it.
I wonder what Lance Armstrong plus some good EPO could have done with the Atlas.
