Niagara Falls Daredevils.

Aberron of Fogonazos has an interesting article on Niagara Falls daredevils, like this one:

On October 1st 1995, Robert Overacker, a 39-year-old man from California, went over the Canadian Horseshoe Falls on a single jet ski. Entering the Niagara River near the Canadian Niagara Power Plant, he started skiing toward the Falls. At the brink, he attempted to discharge a rocket propelled parachute that was on his back. It failed to discharge. His brother and a friend witnessed the stunt. His body was recovered by a tourists ship.
