National Geo "Spitfire"

[BEAR]

I know very few of you will believe this but in 1966 I was attending the American High School in Bushey, London. I had to stay late because my older brother played football and he was my ride home to Harpenden. While I was doing homework in one of the empty classrooms I heard an aircraft approaching. My first thought was "That's a Spitfire!". When I ran outside there in the evening sunshine was this "glorious Spit" flying low and slow over the school. After watching him disappear over the trees I suddenly thought "How do I know what a Spitfire sounds like?" I had never seen one in flight or heard its engine.
So now I think I am a reincarnated Spit pilot
By the way some years later I found out that they were filming The Battle of Britain during this time.
