No New York skyscraper stunt for Wallenda NIK Wallenda's hope of tightrope walking between New York's most famous skyscrapers just isn't going to fly, the city's top police officer says. NYPD Commissioner Raymond Kelly was asked on Monday (local time) about the possibility of Wallenda, a member of the famous "Flying Wallendas" circus family, walking a tightrope between the Chrysler and Empire State buildings. The daredevil completed a walk over a Grand Canyon gorge on Sunday, walked over Niagara Falls a year ago, and was eyeing New York City for his next death-defying attempt. "I would say no," Kelly said. I think it's dangerous. He walked across the Grand Canyon, and obviously there's water at the bottom of the Grand Canyon. Here, there's thousands of New Yorkers who certainly could be put at risk. So I don't think it would be wise in this city. Wallenda, 34, walked without a safety net or harness, 460 metres above the Little Colorado River on Sunday. The 22-minute walk on 50-millimetre cable was watched by people all over the world on television and computer.
