2009: Mr. Rossy attempts a record-breaking 38-kilometre flight from Morocco to Spain on his Rocket Man wing. He makes a successful leap from the launch plane and deploys his folding wings, but he is forced to abort the flight after he flies into massive clouds. He deploys his parachute and lands safely in the ocean.
