Summer 2018. The 1500 km epic biv Flight of Damien LACAZE and Antoine GIRARD in the core of Himalaya and Karakorum mountains. This journey is actually a prelude and acclimatization to climb the Spantik (7027 m) from the nearest city in two days, thanks to paragliding. Is it really achievable ? What are the limits of such an escent ? Can we really come back unscathed ?
