My first posting after Flying Training was to Benson on the Argosy in 1962.
There was a Corporal in the General Office who sported wings and a DFC etc. He had been field-promoted during WW II to Wg Cdr in charge of a Mustang Wing and he left in 1946 in his substantive rank of Sgt Pilot.
He hated civvie street so much that he re-joined as an airman.
