Yes, a great movie. The scenes inside the Enola Gay were superb.
There is a great book by Bob Greene about Paul Tibbetts called “Duty: A Father, His Son, and the Man Who Won the War”. I read it years ago...but bought it just last year or so. It had a whole new meaning after my father passed away. http://www.amazon.com/Duty-Father-His-Son-Man/dp/B000C4SILM
