Before he became famous as a college football coach, Paul Dietzel flew B-29s against Japan. https://ww2thebigone.com/2016/09/09/before-his-football-fame-world-war-ii-shaped-paul-dietzel/
I always wondered why he left LSU after winning the National Championship for Army. I never knew that he was a B-29 pilot. Later on in the 80s, he came back to LSU as the AD. Great story.
