As man approached the 20th Century, the race for the skies captivated the imagination of inventors everywhere and all kinds of bizarre flying machines were conjured up. Included in the mix was a pedal-powered ancestor to the helicopter, patented a decade before the Wright Brothers first conquered the skies. By all indications, it was never built or tested, but if this anonymously designed machine can actually lift off, it would be a history-making moment. Join Re-Inventors Matt and Jeremy as they take this chopper on a test flight.
