2 plans to rescue daredevil Wallenda Nik Wallenda walks a high wire that's over 1000 feet long and 200 high above the Allegheny River and Roberto Clemente Bridge without shoes as part of the Three Rivers Regatta in Pittsburgh on July 3, 2009. Wallenda is the seventh generation of the legendary Great Wallendas, who have performed in circus acts since the 1800s. UPI File Photo/Archie Carpenter NIAGARA FALLS, Ontario, June 9 (UPI) -- Canadian and American authorities have a backup plan to rescue tightrope walker Nik Wallenda should he be stranded during his walk across Niagara Falls. The plan is a backup to Wallenda's own rescue plan, which would use a system of pulleys and baskets, The Buffalo (N.Y.) News reported Saturday. "One of the conditions of the Niagara Parks Commission contract with Nik Wallenda was that he was supposed to furnish his own rescue plan," said Douglas Kane, chief of the Niagara Parks Police Service in Canada. We've reviewed it. We're happy with it. Park police in Canada and the United States purchased a $3,800 zipline system to use should Wallenda fall and be left dangling from a tether attached to the 2-inch cable spanning the Niagara gorge. A team of 10 park police have been practicing using the zipline on a weekly basis since April. "So we do have a backup plan to their backup," Kane said. However, I think his should suffice. About 120,000 spectators are expected on site to watch Friday as the daredevil attempts to walk a tightrope from the U.S. to the Canadian side of Niagara Falls.
