Man survives blindfolded walk between two skyscrapers

Nik Wallenda survived two tightrope walks between skyscrapers on Sunday without a harness or safety net - and even performed one of them blindfolded.

Thousands of fans watched the 35-year-old complete the back-to-back walks between Chicago's two Marina City towers.

His first walk began at 588 feet but was at a 19 degree angle, and set a world record for the steepest tightrope walk. The second walk, for which he was blindfolded, was at 543 feet.

Wallenda is the great grandchild of daredevil Karl Wallenda, who died during a tightrope stunt in Puerto Rico age 73. He is the heir to the flying Wallendas group of circus acts who are known for performing highwire acts without safety net.
