Have you seen Alain De Cadenet when he's being filmed talking about the Spitfire and its history, when one takes off right behind him?
My dad always used to say that to.Until a couple of years ago, my parents lived within sight of Coningsby and having grown up living by the Thames Estuary during the war, my Mum would say instinctively every time the Lancaster or a Spitfire went over 'it's ok, it's one of ours'!
