David Blaine, known for his headline-making spectacles of physical, emotional and mental endurance, will live on the line — literally. Blaine, the ‘Upside Down Man,’ will attempt to hang from a thin wire five stories in the air — with no safety net or airbag to break his fall — in Central Park’s Wollman Rink for three days and nights. Using electro-magnetic boots, Blaine will walk on and under the wire during more than 60 hours of the challenge. How will he exit from his perch overlooking New York City? Details of Blaine’s heart-stopping plunge at the conclusion of the special are a closely-guarded secret. He will surprise us all — live — on a new, two-hour ABC primetime special, David Blaine: Dive of Death, WEDNESDAY, SEPTEMBER 24 (9:00-11:00 p.m., ET), on the ABC Television Network.
