A daredevil bird man has pulled off a heart-stopping stunt by risking certain death to fly through a tiny hole in a mountain side.
Wingsuit flyer and base jumper Alexander Polli performed his incredible flight at the Roca Foradada Mountains in Montserrat, pain, where he targeted a local landmark known as 'The Bat Cave'.
The gap in the mountain is just six feet wide at its narrowest point, and with Polli travelling at 155mph during his wingsuit flight he would have been killed instantly had he made the slightest miscalculation.
Yet the danger only made his success all the more triumphant, and Polli has quickly become a hero to thousands across the world after posting video of his stunt on the internet.
As for why he does it? Polli tells all on his Twitter account: "Life is measured not by the amount of breaths you take, but the amount of times you have your breath taken away."
The predictable internet trolls have begun to try and claim that the stunt was in some way produced with camera trickery.But Polli is clearly delighted by the idea that some think his effort was too good to be true: "It honestly makes me verrry (sic) happy when people think it's fake."
