A massive human-powered helicopter designed by Canadian duo Cameron Robertson and Todd Reichert has recently won one of the longest-standing challenges in aviation history. “The Atlas” is controlled by having a single pilot pedal a bicycle-like wheel to turn the aircraft’s four enormous, independent rotors. On June 13th, this human-powered helicopter reached a height of nearly 11 feet and stayed in the air for 64.11 seconds. Impressive? I think so!
