Not unmanned but heck of an achievement.

On July 31st and August 2nd, 2010 the Snowbird succeeded in completing several sustained flights!! On the longest flight the altitude and airspeed were maintained for 19.3 seconds, setting a world first, and achieving the age-old aeronautical dream of self-powered flapping wing flight! The accomplishment of our goal is a success shared by all, and I must thank everyone who was involved for their help, sponsorship, advice, or simply for their interest in our project, which has motivated us when times where hard.
