This is video of daredevil Nik Wallenda walking 1,500 feet, on a 2-inch-thick cable, 1,500 feet above the ground, on Sunday night.

The 34-year old Wallenda set a new world record by completing the quarter-mile walk, across the Colorado River Gorge in Arizona, in just under 23 minutes.

Wallenda, who made the historic tight-rope walk on the Discovery Channel, was not wearing any kind of harness, nor was there a safety net.

Here's the entire walk, as seen on the Discovery Channel, if you missed it, or want to see it again.
