Nik Wallenda (a member of the famous Flying Wallendas family) completed his latest high-risk walk on Sunday night: treading two city blocks of a wire suspended between two Chicago skyscrapers over 500 feet tall. He accomplished the feat while 50,000 fans (including a group who call themselves the Nik Chicks) watched and the Discovery Channel broadcast live. Wallenda completed the second leg of his walk blindfolded—the first time he has attempted that dangerous move.

NBC’s Willie Geist and Natalie Morales, along with the Weather Channel’s Jim Cantore, hosted the Discovery Channel’s Skyscraper Live. Wallenda scrapped his plans to take a selfie mid-walk, but he did take one with Morales before attempting the blind walk.

Wallenda said his plan for his next highwire feat is to replicate a walk done by his great-grandfather, which will require him to do two headstands while crossing a wire 600 feet in the air.
