Duty: A Father, His Son, And The Man Who Won The War
If you would like to learn more about Colonel Paul Tibbets, I recommend the book "Duty: A Father, His Son, And The Man Who Won The War" http://www.amazon.com/Duty-Father-His-Son-Man/dp/0380978490/ref=ed_oe_ h by Bob Greene.
This book was written 55 years after the bombing of Hiroshima. It tells a very comprehensive story about Col Tibbet's WW II service in both Europe and the Pacific and his life after WW II.
Highly recommended.
