There was a Constellation parked in the Western Dispersal of RAF Changi in the early sixties..that had an Ace of Spades on the tail! Trouble with the number three engine meant that it was parked there for a very long time, with the Chiefies earning pocket money by taking it to bits and then putting it together again. The hoped for engine change never materialised so eventually the engine was fired up, along with the others, and they departed (heading West). As soon as the wheels were up number three was feathered and they continued on their way. Not too sure if that meant they were Aces.
