A man with a prosthetic leg made history when he climbed the 103 flights of a Chicago skyscraper on Sunday, the Associated Press reported.
Zac Vawter, 31, was wearing a "bionic" leg being controlled by his mind during his ascent to the top of Wills Tower, one of the tallest skyscrapers in the world. The event, "SkyRise Chicago", was put on to raise money for the Rehabilitation Institute of Chiacgo.
Vawter's climb with the bionic leg was the first public glimpse of the new technology, the Associated Press wrote.
Vawter made it to the top in 45 minutes.
