As a brand-new corporal posted to the Air Ministry commcen in 1964 my first job was to escort an SAC under "close arrest" to his court martial (he was drawing married allowance but living in quarters with a woman who was not his wife). I was rather surprised to be told to meet the SAC at Charing Cross underground station and deliver him to the court martial. I stood on the platform waiting, then an elderly SAC came up to me, introduced himself and we both walked to the building (location long forgotten) where I handed him over to a RAF policeman at the door. Very weird!
