I once had to refuel a Hastings in a howling gale at Keflavik on the way to Christmas Island via Goose Bay. To get to the fuel tank cap I had to remove a disc of the wing's skin that should have been attached by a bonding wire. It wasn't. It slipped out of my frozen fingers and set off on it's edge downwind at a great rate. I slid off the wing and set off in pursuit. It went b****y miles before fortunately fetching up in a snow drift. It was a long cold plod back up-wind to the aircraft. Configuration Deviation Lists hadn't been invented then or I might have been tempted.
