The French speedrider charged down a steep line across a glacier at the foot of Europes highest mountain under the cover of darkness find out how he pulled off the historic feat now.
Valentin Delluc is a pioneering speedrider whos flown down a French glacier at night to make his Moonline concept become a reality. He spent seven months training for the feat which saw him tackle a challenging line in the dark across the rugged crevasses of the Bossons glacier at the foot of Mont Blanc.
The idea for the project was born at the end of the summer of 2016, but Delluc had to schedule many test runs to hone the aerodynamics of his wing in order to make sure he could fly it with LEDs attached. As a result, Delluc conducted the first test runs without the lighting at an altitude of 2,800m until the device worked and he only moved over to using the real lit-up wing when everything was fine-tuned. Then the final test flight took place under the light of a full moon, which allowed Delluc to fly even closer to the ground.
