Lost in Karakorum

The epic 1500km bivouac flight of Damien Lacaze and Antoine Girard, two French paragliders and mountaineers, through the heart of the Himalayas and the Karakoram ranges. This journey is actually a prelude and acclimatization for their attempt to climb Spantik (7027m) from the nearest town in two days, using only paragliders. Is it truly feasible? What are the limitations of such an ascent? Can they earn a living from it?
