On May 23, 1971, a French expedition led by Robert Paragot successfully climbed Makalu via its west pillar. Makalu is one of the five highest peaks in the world, located in the Himalayas on the Nepalese-Tibetan border.

On the return to base camp, Jean-Pierre Janssen interviewed Lucien Berardini, Georges Payot, Jean-Claude Mosca, François Guillot, and Jean-Paul Paris, all of whom played a key role in bringing Bernard Mellet and Yannick Seigneur to the summit. Expedition members: Robert Paragot (expedition leader), Georges Payot, Yannick Seigneur, Claude Jager, Jean-Claude Mosca, François Guillot, Bernard Mellet, Lucien Bérardini, Jean-Paul Paris, Robert Jacob, Jacques Marchal (surgeon).
