Project X meets the scientists and inventors who are pushing the limits of flight: from new machines with amazing designs to the human body itself. Dr. Fleck takes a ride in a hang glider to help illustrate the basic physics of flight. Marc then goes skiing in a wind tunnel to unlock the secrets of an Olympic Gold alpine jump. Together they take a look at the human contribution to flight — rocket science. Dr. Gardy picks up a few tips from some of Canada’s top fighter pilots on how to sustain performance. And Dr. Alters gets up close and personal with the only mammals capable of really flying — bats.
