A man has crossed the Grand Canyon on a tightrope without a a safety harness in 22 minutes.

Nik Wallenda, an 'aerialist' from Florida, murmured prayers to Jesus under his breath as he performed the stunt on a skywire 1,500ft above the Little Colorado River Gorge in Arizona.

Wallenda crossed the Niagara Falls last year

The quarter-mile walk was broadcast live on the Discovery Channel, with many viewers saying they felt sick just watching him.

He was forced to kneel twice on the two inch thick steel cable, to "get the rhythm of the rope" and maintained a steady step all the way across apart from jogging and hopping the last few steps.

His leather shoes had an elk-skin sole to help him grip the cable as he moved across.

Next on his list is a skywire walk between the Empire State building and the Chrysler building in New York.
