Nik Wallenda put heavy wind and extreme levels of spray to one side to walk on a tightrope from one side of Niagara Falls to the other.
He is the latest in a long line of members of his family to have completed a heart-stopping manoeuvre high above the ground.
The daredevil started on the US side of the iconic waterfall and made the 1,800 ft trip to Canadian land on a two-inch wire, which was suspended more than 150 ft above the ferocious water.
Thousands of people gathered to watch him become the first person to cross the Falls in this way for more than 100 years.
It is the latest stunt in a catalogue of breathtaking challenges undertaken by the Wallenda family dating back over 200 years. Nik is the seventh generation of the Flying Wallendas.
He is only too aware of the dangers of tightrope walking, having lost two members of the family in previous accidents. He was therefore ordered to use a safety harness by sponsors ABC, who said they would stop broadcasting if he removed it.
His great-grandfather Karl Wallenda is one of those to have died, after a 1978 stunt in Puerto
Rico went horribly wrong.
