I keep watching this video over and over and every time this insane guy in a wingsuit somehow manages to avoid smashing into the side of the mountain by perfectly zipping through a ridiculously narrow cave. It's unbelievable. It doesn't make sense. He's flying at 155 miles per hour!

Flyer Alexander Polli is the guy who pulled off the amazing stunt which started with him free falling from a helicopter and ends with him just barely dodging guaranteed death. People are incredible. [Epic TV]
