Watch This Unbelievable Wingsuit Flyer Fly Through a Small Cave Hole

You've probably seen a commercial or show on Discovery channel featuring these guys flying through the air in winged suits. Well, in this video, wingsuit athlete Alexander Polli does an unbelievable tactical flight through a narrow cave on a rugged mountainside.

He jumps out of a helicopter then reaches speeds in excess of 150 mph then precisely flies through this tiny hole on the side of a mountain. The best part is that he's wearing a helmet-cam so you get to experience as if you did the jump.

This is unbelievable.
