Wingsuit-wearing Uli Emanuele jumps off a mountain and flies through a 2-meter-wide hole in a rock formation in Lauterbrunnen, Switzerland.

Emanuele trained for more than three years to complete the stunt.

On his Facebook page, Emanuele describes himself as a “Base Jumper Wingsuit Pilot” who focuses on “places never jumped before and searching for new terrain flight lines.”

“That is the smallest hole ever flown through by anyone,” he said.
