A Canadian-built helicopter that is powered by a human riding a bicycle has become the first winner of a decades-old $250,000 (£165,000) engineering prize.
The American Helicopter Society had never given out its Igor Sikorsky Human-Powered Helicopter Award – initiated 33 years ago – until the team from the University of Toronto won it this week.
The challenge was to create a flying machine that would be able to reach a height of three metres, fly for 60 seconds by human power alone, and stay within a 10m by 10m radius.
“It was long seen as impossible to win this,” AHS International executive director Mike Hirschberg told French news agency AFP.
The winning vehicle is called the Atlas, and was designed by a team of about 20 students and young professionals.
