Threading a needle

This guy has balls the size of Texas. His name is Alexander Polli and he does something spetacular. A tactical flight through a narrow cave on a rugged mountainside. The flight starts with a jump from a hovering helicopter, Alexander reaches speeds of 250 km/h while following a precise trajectory leading to the cave opening, he then fully commits and flies directly through!
