The official record of Mallory and Irvine's 1924 expedition. When George Mallory and Sandy Irvine attempted to reach the summit of Everest in 1924 they came closer than any previous attempt. Inspired by the work of Herbert Ponting (The Great White Silence) Captain Noel filmed in the harshest of conditions, with specially adapted equipment, to capture the drama of the fateful expedition.

Record of the first ascent of Everest made without the use of oxygen equipment, made in May 1978 by Reinhold Messner and Peter Habeler. Could it be done? Would their blood vessels burst? Would they suffer brain damage leading to madness? Nobody was sure. Messner: 'I would never come here for trying Everest with oxygen. That is not a challenge for me.' A fascinating piece of history, well filmed by Leo Dickinson and Eric Jones (above the South Col Messner used a cine camera to continue the filming), featuring Messner and Habeler's thoughts. The film follows the usual sequence from Namche to Base Camp, through the Icefall, to Camps I, II and III. It also shows historical footage of the pioneering Mallory and Shipton expeditions.

In 1924, British climber George Mallory and his partner Andrew Irvine attempted to conquer Everest for the third time. They never returned. Could they have been the first to successfully climb the mountain before meeting their deaths? In 1999, German geologist Jochen Hemmleb discovered Mallory's body just below the summit, reigniting speculation. In 2010, he organized a new expedition to follow up on this sensational discovery. His goal: to find the base camp from which Mallory and Irvine set out to conquer the summit.
