Flying with muscle power

Gamera II is the name of a human powered helicopter from the University of Maryland. It broke a record by flying for 50 seconds, piloted by doctoral student Kyle Gluesenkamp. The Sikorsky Human Powered Helicopter Prize requires a 60-second flight with 3 meters altitude. The pilot weighted 60 kg, the copter itself 34. The rotors have 13 meter diameter and turn 20 times per minute. No cheap bike yet with 150 K dollars, and also size wise yet quite ready for your daily commute.
