NIAGARA FALLS, Ontario, June 7 (UPI) -- Daredevil Nik Wallenda's planned tightrope walk across the Niagara Falls gorge has hit an international bureaucratic snag over airspace.
The Canadian helicopter company that was scheduled to begin stringing the cable from the Canadian side to Goat Island on the U.S. side informed Wallenda they had Transport Canada's permission to do the work, but didn't have a permit from the Federal Aviation Authority.
