Nik Wallenda's daring walk across the Niagara Falls
Nik Wallenda became the first person to walk across the Niagara Falls on a tightrope on Friday. Starting on the American side, the aerialist tiptoed 550 metres across the churning water before stepping onto Canadian soil. Despite the nail-biting nature of the walk, Wallenda granted interviews during his stunt, raving about the 'unbelievable view.'
