American wingsuiter Jeb Corliss has completed a "flying dagger" jump by gliding through a 10ft fissure in a mountain in China at 100mph.
Corliss, 37, was filmed leaping from a helicopter with his wingsuit and flying through the 10ft gap in the rock of Langshan Mountain, in Zhejiang Province.
The crack in the rock was the narrowest point in the 900ft tall shard of rock.
Once through the gap, Corliss deployed his parachute and landed near a waiting crowd on the side of a hill.
"I was really worried that it wasn't going to happen. I was sure it wasn't going to happen. I've no idea. I just didn't want to disappoint everyone," he added.
Since 1999, Corliss has broken his back, leg, and both ankles in various wingsuit jumps.
