A "bladerunner" has been filmed BASE jumping off a 200ft high wind turbine blade.
The film shows the man walking out along a long turbine blade which is not moving due to the calm conditions.
The man makes it most of the way along the blade when gravity triggers it to start falling.
The man then counts down: "3! 2! 1! Seeya!
He then plummets off the drops before his parachute takes him safely to earth.
The video is also shown in another way - from the man's helmet headcam.
The clip was filmed by Negative4 Productions.
"There are moments in life that are surreal," the company said.
"BASE jumping is widely regarded as the most dangerous sport in the world.
"When a jumper adds a little creativity to danger, you get the phenomenon we call 'blade running.'
"Once the jumper gets to the top of this 200ft wind turbine, he makes the walk of his life.
"After getting his bearings, he calmly yet gingerly steps onto the stalled - but still movable - blade.
"In an almost surreal action, he walks nearly the entire length of the 150ft blade.
"But, at the point of no return his forward motion starts to make the massive blade move beneath his feet.
"Now that the blade is going down, the athlete can no longer turn back, and he jumps!"
