1973/74 ish, and newly minted TA capt in RCT(V), on Movement Officers Course at Prince William of Gloucester Bks (ie RAF Spitalgate that was). Tradition established (we had a former cavalry officer with us) of champagne only after 2300 hours. Someone started telling ghost stories, mostly with an aviation bias, and there were rumours of a ghost in the mess. Next morning Scottish subaltern goes to the Colonel and resigns on account, he says, of the ghost in the Mess.
