Watch on SFlix. In October 1984, Pierre Béghin, an engineer from Grenoble, and Jean-Noël Roche, a high-mountain guide, completed the Himalayan ascent of Dhaulagiri (8,172 m). The expedition's context: seven people crossed Nepal to Muri, collected accounts from trekkers—including that of the author Robert Rieffel—and attended Sherpa prayers at base camp. Then, the two of them embarked on a rocky and snowy route without supplemental oxygen. At over 5,000 meters, on the mountain of winds, Jean-Noël Roche made a paragliding flight. The climbers brought back footage with their Super 8 camera from 6,500 meters, but only photographs have been able to confirm their presence on the summit ridge of the seventh highest peak in the world.
