My school had a 'Film Club' on a Saturday night displaying such films as Genevieve etc.. The audience would be parents/relatives all sitting on very small chairs in the gym. The Dambusters, newly released, was on the menu so the FZ family duly attended. Before the show a Flight Lieutenant stood up and told us all the history of it - he looked rather worried and very ill at ease which I thought was the result of being confronted by a such a load of kids.
It was only many years later that the penny dropped about the discomfort of the F/L, poor s*d, ... in the audience was my mate's father - Marshal of the Royal Air Force Lord Tedder.
The Bomber Command memorial is exceptionally moving - RIP
