Jeffrey Quill-Spitfire
May I recommend the Jeffrey Quill book: "Spitfire-A Test Pilots Story".
A friend of mine gave me a copy to read in the early 90's and I thought that, except for the time interlude and that fact that I was in the rotary wing business, Mr. Quill might have been describing the sorts of issues that were everyday business at Sikorsky. He had a marvelous writing style and hid what had to be an enormous talent with admirable humility and grace.
