I've posted wingsuit videos here from time to time. This one's from the testing of a new design of wingsuit, and begins with splitting twin rock pillars on the Sass Pordoi in Italy. It continues with a jump from Les Vuardes in France. I recommend watching it in full-screen mode.
I still say you can't pay me enough to make me fly that close to a mountain at those speeds. A highly experienced wingsuit jumper was killed last year on the Sass Pordoi doing just that.
