en CB01 OFFICIAL. A feature documentary about the people and the planes that helped win World War War II. Through people personally connected to the events, the film investigates the story of how the Spitfire, its stable-mate, the Hawker Hurricane and its great adversary, the Messerschmitt 109 came into being during the huge advances in aviation in the interwar period—and then how the pilots fared in combat, three miles up in the skies over Europe, Africa and Asia.
