Tancrede and Julien, also known as the Flying Frenchies, have developed a whole new way to boost your adrenaline. On top of base jumping and paragliding, they’re also pioneers in highlining, which basically means walking on a thin metal cable above the nothing.  This two friends seem to have no fear and they’ve proved it crossing from one parisian skycraper to another, defying gravity in the Alps, and, as this film by Sebastien Montaz-Rosset proves, laughing in the face of death in the Norwegian Fjords.
