Took son and his friend (both then about 10 or 11) to Duxford and we are in the Land warfare bit, and the Monty caravans. Showing on the closed loop is the D Day landing and the famous clip of the landing craft ramp going down opposite the single house on the shore near Ouistreham. Watching it are an elderly lady and gentleman. I apologised for the noisier of the two boys (young W, heavily into all things military). "Not to worry she said, just my husband was behind the camera man watching him film, but has never seen the film itself". I offered to remove young W, who by now was quizzing the elderly man. "No leave him" she said. " My husband will find it easier to talk to your son about his experience than to me." And the two talked earnestly for about half an hour. Young W still talks about the experience 14 years later.
