For First World War aviation enthusiasts, this contains a multitude of brief biographical sketches of various pioneers of aerial combat, from Roland Garros, the first ace, to WWI's ace of aces, Baron Manfred Von Richtofen. 
 My favorite is the story of Lt. Louis A. Strange, who nearly lost his life while engaing a German observation plane, when he attempted to change the jammed drum magazine of his upper-wing mounted Lewis gun only to fall out of the cockpit when his aircraft turned upside down. In his words, "There I was praying that the drum would stay on, when moments before I had been cursing it for being stuck!" He eventually kicked the control stick over to right the plane, and dropped back into the cockpit. Years later he encountered the German pilot, who complained that he hadn't been able to convince anyone that the last he had seen of Strange was his plane descending in an upside down spin, with the pilot hanging onto the machine gun for dear life. To which Strange replied, "What about me? I never could explain how I kicked out all the instruments from my instrument panel!" 
 I used to have a 16 x 24 poster of Lt. Strange going down hanging from the drum of his Lewis gun; and years later found "Hero's of the Sunlit Sky" and got the full background story from Arch Whitehoiuse.
