FILE - In this May 31, 1976, file photo, Karl Wallenda walks on a cable 200-feet above the playing field at Veterans Stadium between doubleheader baseball games in Philadelphia, Pa. Wallenda unfurled a bicentennial and American flag from his balancing bar after doing a headstand midway across the 640-foot span steel cable. The walk took 18 minutes. The patriarch of the famous German high-wire-walking family plunged to his death on March 22, 1978, while attempting to cross a wire strung between two hotel towers in San Juan, Puerto Rico. Although the 73-year-old Wallenda had performed much more difficult stunts, a wind gust caught him off guard this time and he fell. (AP Photo/Bill Ingraham, File)
