French Base jumpers Frederic Fugen and Vincent Reffet – who broke a world record after leaping off the Burj Khalifa in Dubai last year – took to the skies in southern France on Saturday (6 June) to jump over a historic medieval fortress.

The two Frenchmen, who call themselves the Soul Flyers, jumped off a helicopter circling 4,000m above the Chateau de Peyrepertuse, a medieval fortress perched on a limestone ridge at an altitude of 816m.

Fugen and Reffet were joined by Spaniard Horacio Llorens, Frenchman Theo de Blic and Brazilian Rafael Goberna in their vertiginous pursuit.

The stunts over the 11th century chateau included a series of base-jumps in wing suits, paragliding and parachuting.

The Soul Flyers broke a Guinness World Record for the highest base jump in 2014 when they plunged down the top of the Burj Khalifa, the tallest building in the world, standing at 828m.

Base is an acronym for buildings, antennas, spans and Earth – the kinds of platforms used by parachutists who free-fall from such fixed points as cliffs, bridges and buildings.
