In summary, the requirements to win the AHS Sikorsky Prize included a flight duration of 60 seconds and reaching an altitude of 3 meters (9.8 ft), with the center point of the aircraft hovering over a 10-by-10 meter (32.8-by-32.8 ft) square.
I assume that's to keep any wise-asses from building a plane/glider instead of a chopper.
