Nik Wallenda Niagara Falls

The amazing Nik Wallenda became the first person to walk across Niagara Falls on a high wire.

More than of thousands of people gathered at the falls Friday night and millions more were believed to be watching on television as Wallenda crossed some 200 feet in the air on a two-inch-wide wire strung over the raging waters of Horseshoe Falls, the largest of the three falls that make up Niagara Falls.He trotted in his final steps across the wire and stepped into Canada, barely 25 minutes after he started.

Others have crossed the Niagara River itself, but never over the falls. Wallenda said that Friday night's feat was the fulfillment of a lifelong dream as well as a chance to honor his great-grandfather, legendary funambilist Karl Wallenda, who died after falling from a tightrope in Puerto Rico in 1978.
