UPDATE: The world of wingsuit flying has lost a great friend and legend, Uli Emanuele. Thanks for sharing your talent and passion with the world, mate. You will be missed by many, but never forgotten.
Original Post: On a scale of 1 to 10, flying a wingsuit through a 2-meter wide cave has a pucker factor of 78! After 3 years of dreaming, training and preparation, there's no turning back for Uli Emanuele as he commits to this epic wingsuit flight yes, through a 2 meter cave! Mind. Blown.
