Checking high voltage lines . . . VIDEO
and then there is Paul Steiner, Red Bull performer from Austria . . .
At nearly 6,000 feet Steiner exits the cockpit of his Red Bull sailplane then proceeds to climb onto the wing as the aircraft begins a roll over. As it continues over, Steiner keeps moving until he is mounted on the underside of the fuselage while the aircraft is upside down. All this before jumping off the plane and sky diving down to the ground.
Be even better, if he got back in and flew it!!!
