Respectfully disagree with your assessement of 'Flyboys.' Not only was he technically inaccurate in many cases, i.e., the B-25 was called the 'Billy,(?)' but he was very much an apologist. He did a great job on "Flags" but he should have stopped there.
There was a great flap in the mid-1990s about the Smithsonian's plan to display the Enola Gay with 'context' that to many seemed an apology to Japan and how bad they had it.
A very vocal and effective campaign of veterans and the Air Force Association stopped that. Eventually, the Museum just displayed the B-29 and let the viewer make his/her own conclusions. That was at the old facility in DC and the bomber was displayed in pieces due to size.
Today, it is reassembled and rests in the new Udvar-Hazy complex at Dulles Airport.
A great book on the development of, and discussions about using, the A-bomb is "The Making of the Atomic Bomb" by Richard Rhodes. Won the Pulitzer Prize as a matter of fact. Don't know if that hurts or helps your view of the book.
He did a follow on about the H-bomb, "Dark Sun" that was just as good.
