Here's the youtube version of the successful flight on Thursday 5-12-11 of the University of Maryland 'Gamera' human powered helicopter. It's an impressive accomplishment no matter how you look at it.
Congratulations to the entire Gamera team and to pilot/powerplant Judy Wexler - first woman to fly a human powered helicopter!
