(NEWSER) – With no harness or safety net, Nik Wallenda's only hope would have been to cling to a cable if things went wrong during either of two death-defying skyscraper walks in Chicago last night—but the daredevil managed to break two world records and survive to tell the tale.

For the first feat, he walked at a record-breaking 19-degree uphill angle on a wire hundreds of feet above the ground, crossing the Chicago River from one skyscraper to another, the AP reports. For an encore, he completed a 94-foot walk between two skyscrapers blindfolded, making it across in just over a minute. At 543 feet from the ground, it was a record height for a blindfolded walk.
