Blindfolded with no safety net, daredevil's incredible 94ft walk between skyscrapers

Daredevil Nik Wallenda wowed Chicago and the world with two skyscraper crossings on a tightrope without a safety net or a harness.

Thousands of cheering fans packed the streets around the city's Marina City towers to watch the 35-year-old, heir to the Flying Wallendas' family business, complete the back-to-back walks, including one wearing a blindfold.

As he stepped from the wire after completing the second leg, he tore off his blindfold and waved to the crowd, who erupted in cheers.

The spectacle was telecast with a seconds-long delay on the Discovery Channel so producers could cut away if Mr Wallenda fell. It took him about six and a half minutes to walk the 454ft-stretch at a 19-degree incline from the Marina City west tower to the top of a building on the other side of a river.

"I love Chicago, and Chicago definitely loves me," said Mr Wallenda as he walked the wire, with the thousands below him screaming in support.

The next stage of his high-wire event he undertook blindfolded - a 94ft-walk between the two Marina City towers, Chicago landmarks. Two of his previous televised tightrope walks - over the brink of Niagara Falls in 2012 and across the Little Colorado River Gorge last year - drew about 13 million viewers each.

Journalists covering the event signed waivers relinquishing their right to claim emotional distress if they witnessed a catastrophe. A year before Mr Wallenda was born, his great-grandfather fell to his death during a tightrope stunt in Puerto Rico. He was 73.
