Tightrope Walker Wallenda Plans Walk Across Windy, Dangerous Grand Canyon 1500 Feet Above Ground; Says Not Afraid of Dying Because of Christian Faith

Record-breaking US daredevil Nik Wallenda hopes to make history again this morning by walking across the Grand Canyon on a tightrope, 1,500 feet above ground over the world-renowned landmark.

Wallenda, who was the first person to walk across the Niagara Falls last year, will be rigged up with multiple cameras and microphones broadcasting the death-defying feat live around the world, reports Yahoo.com.

And unlike the Niagara Falls walk, the 34-year-old will wear no safety harness for the stunt, likely to take him 25 minutes in searing temperatures over the famous tourist attraction.

At Niagara, Wallenda -- who first walked the wire aged 2 -- braved strong winds and heavy spray to walk on a cable suspended around 200 feet (60 meters) above North America's biggest waterfall, on the US-Canada border, according to Yahoo.

On Monday morning, he will step out into the void over six times higher -- a height greater than that of the Empire State Building -- with nothing but a two-inch (five-centimeter) thick steel wire between him and the rocky canyon bottom.

The walk is set to begin from around 6:00 pm Sunday local time, an hour or two before sunset over the Grand Canyon and will be broadcast live in 219 countries by the Discovery Channel, whose coverage will begin at 5:00 pm.

On Saturday, organizers described conditions at the walk site, in a remote area at the eastern end of the Canyon, as "very windy."

Wallenda has been planning the walk for about four years, homing in on a remote location at the eastern end of the mighty geological chasm, on land operated by the Navajo Nation Parks and Recreation.

Sunday's walk across 1,200 feet of rope could potentially be delayed in the unlikely event of winds of above 45 miles per hour, or if there was a risk of lightning. A new attempt could then be made the following day.

There will be a seven- to 10-second delay on the live broadcast.

Wallenda, a seventh generation member of the Flying Wallendas circus family, said that as he steps out he will be thinking of his great-grandfather Karl Wallenda, who died in 1978 after falling from a tightrope.

He has trained for the worst, and said that -- unlike his great-grandfather, who had an injured collarbone and double hernia, and grabbed vainly for the wire before falling to his death -- he would be able to hold on if necessary.

The Florida-based adventurer, who traveled to the Grand Canyon on Thursday for final preparations for Sunday's walk, said his Christian faith is important.

"What I get from my Christian faith is that I know where I'm going to go when I die. And that affects my business, because what I do is risky, and if I die, I have peace," he said.

"I'm not scared of dying."
