US | Niagara Falls Tightrope Walk Over Niagara Falls Will Be on TV One of the Wallendas will try next month By Newser Editors and Wire Services Posted May 11, 2012 2:18 PM CDT Copied Daredevil Nik Wallenda walks on a tightrope above Baltimore's Inner Harbor, Wednesday, May 9, 2012. (Patrick Semansky) ABC is turning an attempted tightrope walk over Niagara Falls into a prime-time television event next month. The network said today that it will devote its entire prime-time schedule to a three-hour special on June 15 with Nik Wallenda's attempt. Part of the show will be an examination of the greatest stunts of all time. Wallenda is a member of the famous daredevil family. His great-grandfather, Karl, fell to his death in a tightrope walk in Puerto Rico at age 78. Daredevils routinely used to make tightrope walks over the Niagara River gorge, downstream of the falls, until the practice was banned. Nik Wallenda's stunt will be the first attempted walk over the falls. Read These Next Negative press coverage should get TV licenses yanked, Trump says.
