I can hardly believe this video clip. It purports to show a wingsuit jumper 'flying' through a natural arch of rock - but the angle is so steep, the opening so small, and the clearances so very, very tight, that I have difficulty believing it. It's possible, I suppose, but everything would have had to go absolutely perfectly, with no errors, a complete absence of tricky wind conditions, etc. Also, the video doesn't show the flyer's perspective fully - it cuts back and forth between shots from different angles.
Watch it for yourself, and see what you think. I recommend full-screen mode.
What do you say, readers? Real, or fake?
