Mohave, AZ (CNN) — It was a breathtaking challenge and it was all caught on tape.
It was walk across the Grand Canyon on a two-inch-wide tightrope, daredevil Nik Wallenda did that Sunday night.
He was 1500 feet above the canyon.
Below was the Colorado River, and he was walking on a two-inch thick rope .
He stopped twice and knelt down to regain his composure and steady the wire quivering beneath his feet.
Nik's great grandfather Karl Wallenda put the "flying Wallendas" together in 1922.
In 1978, in Puerto Rico, he fell ten stories to his death.
