Human-powered helicopter hovers accurately for 60 seconds, beats ‘impossible’ challenge

ScreenHunter_239 Jul. 13 15.01A Canadian duo and their Kickstarter-funded, pedal-powered helicopter have won one of the longest-standing challenges in the history of aviation — keeping a human-powered aircraft hovering up in the air at height of at least 9.8 feet, within a 32.8 by 32.8-foot square, for 60 seconds minimum. The challenge, known as the Sikorsky prize, has withstood at numerous failed attempts since it was established in 1980, 33 years ago, even with a $250,000 bounty. But it was finally bested earlier in June by the Atlas, a gigantic human-powered helicopter designed by Cameron Robertson and Todd Reichert, aeronautical engineers from the University of Toronto, who cofounded a company AeroVelo.

The pair funded the construction of their winning aircraft through a successful Kickstarter campaign last year, and just barely managed to beat a rival team from the University of Maryland, whose craft Gamera failed to stay within the square-foot range required by the prize, as Popular Mechanics reports.

The Atlas is controlled by having a single pilot pedal a bicycle-like wheel to turn the aircraft's four enormous, independent rotors (one at each corner). The entire span of the craft is 190 feet.
