Two daring base jumpers have been caught on video, jumping off the side of a mountain into a plane.
Two members of the Soul Flyers group completed the stunt, leaping off a peak in the Swiss Alps and gliding down to meet a plane mid-air.
Redbull video shows stuntmen Fred Fugen and Vince Ruffet successfully landing inside the plane through an open door, after free-falling 3200 metres.
The stunt took more than 100 attempts to achieve.
Mr Fugen said the stunt was physically challenging, but rewarding.
"It was very complicated for us, as we tried a first time, but we messed up a bit and that sucks so much energy out of you," he told RedBull.
"Going up to 4000 metres, it physically costs a lot. Once I got in, I only thought about one thing - my buddy behind."
Mr Fugen says the stunt was performed in memory of Patrick De Gayardon, the first person to successfully re-enter a plane 20 years ago.
"Right now, our thoughts go to Patrick [de Gayardon], who was the first to re-enter a plane," he said.
"We wanted to do it differently by jumping from a mountain. It is a huge achievement."
