University of Maryland engineering student Colin Gore performs a test flight in Baltimore on Wednesday, Feb. 27, 2013, in a one-man, human-powered helicopter that he and fellow students designed and built. The team of undergraduate and graduate students hope to claim the $250,000 American Helicopter Society Sikorsky Prize, which has remained out of reach since it was first offered in 1980. In order to win, a helicopter must fly under human power for at least 60 seconds and momentarily reach an altitude of 3 meters while remaining within a square that is 10 meters by 10 meters.
