Last night, Nik Wallenda fulfilled his lifelong dream of becoming the first person to ever walk across Niagara Falls on a high wire.

As millions watched on live television, the 33-year-old daredevil traveled 1,500 feet some 200-plus feet in the air on a two-inch-wide coil. The stunt took just over 25 minutes, and was all kinds of awesome.

Others have crossed the Niagara River itself, but never over the falls. Wallenda said that Friday night's feat will be 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.

After he greeted his wife and family, Wallenda was approached by customs agents, who asked him for his passport, which he presented.

"No, I'm not carrying anything over. I promise," he said.

"What is the purpose of your trip sir?" the agent asked.

"To inspire people around the world," Wallenda said.

Wallenda said the mist and the winds midway across the walk were the biggest challenge.

"It's all about the concentration, the focus, and it all goes back to the training," he said.
