Love this great NPR piece about engineering students at University of Maryland trying to win a three-decades-old contest for human powered flight. The Igor I. Sikorsky Human Powered Helicopter Competition offers a $250,000 prize for a human-powered helicopter that can fly for 60 seconds, reach a momentary altitude of 3 meters, and stay within a 10 meter square. The Maryland students are getting very close to that lofty goal.
