A number of people have tried to ride over the edge of Niagara Falls, but nobody had a crazier plan than Robert Overacker. In 1995, this daredevil attempted to ride a rocket-boosted jetski over the falls and parachute to safety. The problem was that water tends to make things get wet. Not only did the rocket fail to fire, but his parachute failed to open as he plummeted over the edge. He never stood a chance.
