The 2011 video, Sense of Flying (below), gave viewers a remarkable look at Espen Fadnes flying down mountain sides at speeds of 155 miles per hour. If you saw the video along with 2.5 million others, you perhaps wondered: What could be going through this guy’s head? Well, now is your chance to find out. A newly-released video, Split of a Second (above), gets into the psyche and motivation of the Norwegian Wingsuit World Champion. It also shows the extent to which this guy really lives on a razor’s edge. Strap yourself in. Put on your crash helmet. And enjoy the ride.
