For John, BLUF: Heroes to me. Nothing to see here; just move along.
Since it is the about The Battle of Britain, the source is appropriate, The Pilot. Today is Battle of Britain Day. This is a nice writeup by George Weigel, "Remembering 'The Few'". However, the photo seems inappropriate, although a single RAF bomber raid on Berlin, which caused the German Government to switch from a winning approach to bombing cities, was important—an asymmetric tactical approach with strategic implications.
As Mr Weigel says, there are the men and women of Fighter Command, and especially The Few, to be remembered today, and may they rest in peace.
And, as a footnote, the pilots in Fighter Command were not just the English, the British, but also Canadians, Poles, Czechs, Aussies, Kiwis. Immigrants, if you will.
