Late Tom Ferebee (Bombardier) did NOT like this movie!
I had the pleasure of meeting the late Tom Ferebee about ten years ago - and he did NOT like this movie at all. He seemed very upset by it. He did recommend one movie . . . not sure what it's called - but it came out not too long after the war was over.
The book "Return of the Enola Gay" - mentions the movie's name.
