US daredevil Nik Wallenda became the first man to cross the Grand Canyon on a tightrope Sunday, completing his latest record-breaking feat in just under 23 minutes.
Record-breaking US daredevil Nik Wallenda hopes to make history again this weekend by walking across the Grand Canyon on a tightrope, 1,500 feet above ground over the world-renowned landmark.
He's at it again. The US tightrope artist who crossed Niagara Falls last year will try to do the same at the Grand Canyon -- but this time much further up and without a safety harness.
