We've seen some pretty spectacular wingsuit flying on the Brevent over the last couple of years and there have been a fair number of deaths as other pilots try to emulate their heros. However little comes close to this flight by Graham Dickinson and The Great Dario.
Travelling at 180km/h they pretty much tough trees and rock faces as they fly between the various couloirs on the face above Chamonix in the French Alps.
Here's the view from Graham's helmet cam looking back at Dario. A couple of very close shaves with trees there. More wingsuit madness on Graham's Facebook page http://www.facebook.com/supremeaircommander
