The Supermarine Spitfire was one of the finest bits of British, or indeed general, aeronautical engineering in the history of flight.
It won the war against the Hun and Il Duce and kept Britain's skies free and safe for a decade and then the skies of many a nation well into the '50s.
There is, however, one thing that eludes me. A particular quote about the machine itself. I remember one of the lines contained a phrase like "we made a bird with wings of steel" or "a bird made of steel". I cannot, bloody, find it and it's driving me crazy.
Could I get some help with that?
