I agree, all true.
T. B. - "In real life, the Nazis were already developing methods of lofting bombs across the Atlantic. The V-2 was just the start."
One thing not widely known is that the initial development of the B-29 was done to make an airplane capable of flying from North America to Europe and back, non-stop. It was projected that Germany would occupy England.
As England wasn't invaded, there was no need for it, and the B-29 worked just as well in the Pacific Theatre, where the distances were comparably great.
