NEW YORK (AP) ― Discovery Channel has announced May 4 as the airdate for a documentary on last week’s Mount Everest avalanche that killed more than a dozen mountain guides.

The 90-minute special, “Everest Avalanche Tragedy,” will air at 9 p.m. Eastern time.

Several of the Sherpas killed were helping prepare for American Joby Ogwyn’s (JOE-bee OH-gwinn) planned jump from the summit in a wingsuit. Discovery planned to telecast the stunt on May 11. Thirteen bodies were recovered at the mountain‘s treacherous Khumbu Icefall, with three people still missing.

Earlier this week, Discovery canceled the jump.

The network said the documentary will include footage of the rescue attempts as well as eyewitness accounts. It will serve as a tribute to all the Sherpas and their families affected by the tragedy.
