Video: Wingflyers fly into a plane in mid air over Swiss Alps
These Red Bull wingflyers managed to pull off an incredible stunt over the Swiss Alps.
Fred Fugen and Vince Reffet flew in through the open door of an aircraft in mid-air after freefalling from the summit of the Jungfrau in the Swiss Alps.
It took more than 100 test flights and a first attempt had to be abandoned.
Reffet said it was "an incredibly difficult challenge".
“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. Going up to 4,000 meters, it physically costs a lot. Once I got in, I only thought about one thing, my buddy behind.”
