Niagara Falls

Nik Wallenda, a member of the famed "Flying Wallendas" family of aerialists, has completed an historic tightrope walk over Niagara Falls.

Nik Wallenda will attempt to become the first man to walk across the Niagara Falls on a tightrope in 100 years.

Stuntman Nik Wallenda will challenge himself once again by walking across the Niagara Falls on a two-inch-diameter cable, unharnessed.
