Fugen and Reffet, French BASE jumping experts known as the Soul Flyers, nailed the jump as a 20-year anniversary homage to a stunt performed by Patrick de Gayardon in 1997.
This is a common thing, one imagines, for wingsuiters to do.
It took more than 100 test flights and a first attempt that had to be abandoned, but the Soul Flyers finally achieved the seemingly impossible. Watch these guys fly into an airplane in the Swiss Alps.
Two wingsuit flyers jumped from the summit of a mountain in the Swiss Alps, landing inside a moving plane in what can only be described as an insane stunt.
French wingsuit flyers recently completed an unbelievable stunt following a B.A.S.E. jump from the top of the Jungfrau mountain in Switzerland.More news: Gainsborough branch of NatWest to close next year

The Pilatus Porter light aircraft was expertly flown by experienced pilot Philippe Bouvier and navigated by project coordinator Yves "Jetman" Rossy.
How do you make wingsuit flying more nuts?
A first attempt had to be abandoned but eventually conditions were deemed ideal.
In the video, the Fugen and Reffet use the suits to control their flight, diving through the plane's door - which measures just 1.6m x 1.25m - at speeds of around 140km/h. Going up to 4,000 meters, it physically costs a lot. "It is a huge achievement".
