Nik Wallenda breaks two death-defying tightrope records while blindfolded (VIDEO)

For those of you who think Ben Roethlisberger's second straight game throwing six touchdowns Sunday night was pretty grandiose, ask yourself, "Could he do it blindfolded?

Well that's exactly how Nik Wallenda successfully did a nerve-wracking, daredevil high-wire challenge airing at the same time as the Steelers-Ravens game last night. Wearing a blindfold!

Wallenda (of the famed family of highwire performers) crossed the Chicago River on a tightrope at a height of more than 50 stories — walking at a 19-degree incline for the Discovery Channel. He made it more difficult by doing it blindfolded and without a safety harness or net between the west and east Marina City towers. 

The man with real nerves of steel slid his feet along the wire and followed a pinging sound as his father guided him. Footage, airing on the Discovery Channel, ran on a 10-second delay so producers could cut away if he fell to his death. He said his only back-up plan if things went wrong would be to attempt to kneel and cling to the wire with his feet.

Even while Wallenda was still carefully shuffling his way across the Chicago River, that bastion of information, Wikipedia, already declared him dead. 

And other social media commentators quipped about Chicago's reputation for gun violence — saying Wallenda was safer 50 flights above the street than trying to walk across it.

Here's the view Wallenda missed seeing:

Wallenda sets sights on tightrope walking across Manhattan

As if a breathtaking tightrope walk across the Grand Canyon wasn't enough of a thrill for Nik Wallenda, now the daredevil high-wire artist wants to cross the concrete canyons of Manhattan.

After completing a gut-gripping tightrope walk across the Little Colorado River Gorge in northeastern Arizona on Sunday, Wallenda said he next wants to stroll the skies between the Empire State and Chrysler buildings — a space of some nine city blocks, reports The New York Post.

If he gets permission to walk between the two iconic Art Deco buildings above the quaint Murray Hill neighborhood below, the stroll would be 4,000 feet, more than triple the length of Sunday's stunt.

He gave no indication if he had yet made any attempt to get permission to perform the feat.

In Sunday night’s high-wire act — watched by millions live on television — the 34-year-old Wallenda walked 1,500 feet above the river gorge, part of the Navajo Nation’s reservation, without a safety harness.

He took just more than 22 minutes, pausing and crouching twice as winds whipped around him so that he could get "the rhythm out of the rope."

The event was broadcast live on the Discovery Channel.

The seventh-generation tightrope walker is part of the legendary "Flying Wallendas" circus family. He earned his seventh Guinness world record when he crossed Niagara Falls last year.

It's one way to get around those tourist-clogged sidewalks of midtown Manhattan.
