A daredevil hurled himself off the edge of a cliff in this incredible footage filmed in Yosemite national park.
Stomach-churning video captures the moment he leaps from the 800ft cliff and plummets towards the earth with nothing more than a single rope to keep him from falling to his death.
Ryan Jenks, a 33-year-old painting contractor is a fan of rope jumping - that's leaping off a cliff while attached to a highline rope safety system.
Though it might seem crazy, it's not something he takes on lightly.
He was planning this jump for more than one year after he decided that this spot in Yosemite National Park was perfect.
The Californian makes videos like this one to put on Youtube, but he doesn't want people to put themselves at risk by copying him.
