My research and use of documentary bits to tell the story of my grandfather who as a teenager went to Canada to train as a fighter pilot for the Royal Air Force during WWII 1939 at the start of the war which was illegal to do as a US citizen back then. He also became a pilot for the US Army Air Force until 1947. He was underage, lied about his age, became a fighter pilot when America was not in the war until 1941.
