Lancaster: Bomber or Fighter?
As an air cadet I was on a coach trip to RAF Hendon in the mid 70's and sat next to an ex-Lancaster crewman. We chatted and he told me that that one day they hosted an American Squadron's personnel.
He was just climbing out of a Lancaster with a party of Americans when he heard the rising tones of four Merlins at full throttle, and looking up saw a Lancaster diving earthwards. It was one of the squadron aircraft with several American guests on board. All stopped to watch as the nose slowly rose and the aircraft soared up and over in a loop.
In the stunned silence that followed one of the Americans turned to him and said, "Is that a bomber or a fighter?"
