A team of French daredevils have taken the internet by storm after their latest stunt in a valley in south eastern France.
French daredevil group The Flying Frenchies have done it again, teaming up with Red Bull to release their latest high-flying stunt.
This time, the troupe rode a surfboard 600 metres above the ground on the Vercors Massif, not far from Grenoble in south eastern France (see map below).
The "surfers" had no harnesses, but were equipped with parachutes so they could BASE-jump to safety below.
The surfboard moved at speeds of up to 75 km/hour, according to the group, and made for some impressive footage, which around 10 million people have seen on Facebook so far.
The brains behind the stunt come from Anicet Leone, who also appeared in the video, said that one of his inspirations for the project came from the death of Tancrède Melet, another group member who died in January while preparing for a show.
