This Saturday, aerial stuntman Jeb Corliss will attempt to fly through a 30-foot-wide crack in a 900-foot long rock in China wearing his wingsuit.

Needless to say, it’s the 37-year-old’s most challenging jump ever  – he’s even giving it a name: “The Flying Dagger.” Because the rock is so long and tall (870 feet), it requires scary-precise flying after he makes the leap from the helicopter.

“A lot of us have done a lot of very precise flights, like I’ve hit the string on balloons, and gone by the arms of the Christ statue, and flown through a waterfall,” he told Outside Magazine. “But in those jumps I was only super precise for a split second—two seconds max. This time, I’m going to have to be super precise for somewhere between 10 to 30 seconds.”

The fissure is so narrow that Corliss won’t be able to deploy his parachute once he’s inside. And that’s the one thing that makes him nervous.

“I’m more concerned with what happens to me when I come out the other end,” he told Outside. “Once you come out of it you can’t get any more altitude. So when I fly out of this thing, I could be deploying my parachute at pretty low altitude. The problem of pulling at a pretty low altitude is that I’m over a jungle and there’s a fairly small landing area. You want to avoid landing in trees whenever possible, but if you have to land in trees, you have to land in trees. So it could be very exciting.”

What’re you doing this weekend?
