Fred Fugen and Vince Reffet took more than 100 practice flights to flawless the hazardous stunt with pilot Philippe Bouvier and co-ordinator and navigator Yves Rossy.
Frédéric Fugen and Vincent Reffet jumped from the Jungfrau in the Bernese Oberland and landed in a Pilatus Porter light aircraft flying at altitude.
After Vince Reffet jumped off a mountain with a wingsuit and landed in a small plane in midair, his first thought was not of the incredible feat he had just pulled off, but of his friend.
The French duo have already wowed millions around the world with their outlandish Soul Flyers wingsuit stunts over Mont Blanc and the Dolomites.
"We're used to jumping from the plane, but here you have to enter into it". They had been through more than 100 test flights and even had one failed attempt they had to abandon before their successful jump, according to Red Bull.
"Going up to 4,000 metres, it physically costs a lot".
The stunt took two months of preparations and the pair actually completed it multiple times in order to shoot the video.
In an interview, Reffet and Fugen said that they wanted to re-create Patrick de Gayardonâ€™s stunt that he performed 20 years back in a wing suit.
