Alexander Polli's stunts would make most superheroes blush.
The body flight professional has become our species' answer to birds, and a recent stunt affirms his place as one of the world's most well-known wingsuit flyers.
Filming in the mountains of northeast Spain, Polli pulled off a move that most daredevils could only dream of. Wearing a wingsuit, he jumped out of a helicopter and sped toward a tiny cave opening at 155 miles per hour.
We'll let you see how the rest of the stunt unfolds.
How in the world do you top that?
