Smuj, that's nearly as bad as the tale of the Captain who fell asleep in the TV room at Goose Bay with his boots off. Seemed a good idea at the time to fill them with water and put them in the freezer. He spent the next 3 days flying in trainers !!! Also removed blue light from RAF Police car en route to Gib, In flight very kindly lobbed it in their blast freezer. Never realised RAF coppers had so little sense of humour.
