I saw this on the NBC show "Rock Center" the other night and had never heard of this man. It was the story of Billy Fiske. He was an Olympic Gold Medalist in 1932 (Olympian in 1928) who also carried the flag in the opening ceremonies of the '32 games.
He faked Canadian citizenship to fight for the RAF and was the first American born citizen to be killed in World War 2.
