If you believe that inline skating is most fun on the surface of the smoothest asphalt, 36 years old Dirk Auer from Gross-Gerau is ready to prove you wrong. In 4200 meters altitude Dirk Auer took a deep breath and climbed through the escape hatch above the cockpit on top of the plane. He was able to stand up and skated all the way down to the tail of the plane where he did a big freefall jump.
