Query: A real hero

As usual Tillman does a masterful job in covering his subject, but this time it was almost a "no brainer". Marion Carl's life was like a nearly unbelievable movie. The man was a true hero. His story from combat pilot, to test pilot and even his tragic heroic death at the hands of a low-life in his own home makes a person regret that he never had the opportunity to meet the man.
