It's the extreme sport that's got thrill-seekers in a tailspin, but the latest wingsuit flying video throws a graceful light on the nerve-jangling hobby.
According to the Huffington Post, cameraman Ludo Woerth films Robert Pecnik as he glides through a river gorge in Europe at 100mph.
It's hard not to think he might crash into a tree or rock face at any moment, but this wingsuit flier is obviously a real pro.
Wingsuit fliers use a special jumpsuit, sometimes called a flying squirrel of birdman suit, to add surface area to the human body to enable a significant increase in lift.
A wingsuit flight ends with a normal parachute landing.
