Wearing a wingsuit, a parachute, and GoPro Hero cameras strapped to his body, Corliss managed to fly through a hole in Tianmen mountain, Hunan Province.
The famous Tianmen Hole in the limestone peak is about 360 feet tall, 96 feet wide, and 260 feet deep.
Corliss dropped out of a helicopter at 6,000 feet and glided toward the cave like a flying squirrel. A GPS display in his helmet goggles kept him on a precise course for his flight, which was about two-thirds of a mile.
As seen in the video below, he shot right through the cave like a bat out of hell, then deployed his parachute on the other side for a safe landing on a bridge.
The event drew intense media coverage in China, as did a 1999 stunt during which light aircraft were flown through the peak.
I'm still waiting for them to figure out how to land without a parachute.
