Daredevil Crosses a Gorge Near the Grand Canyon on Tightrope


It's down to the wire for American daredevil Nik Wallenda - as he attempts to cross a gorge near the Grand Canyon on a tightrope suspended 1,500 feet or nearly 460 meters above ground. Any misstep would mean death for the self-described "King of the High Wire" as he makes his way across without any safety harness or net.
