The bomb is perhaps the biggest leap in the history of weapons, so much that civilized nations are reluctant to use it, and one of the genuises, Opie, that invented it turned away.
From the standpoint of history, or technology, or military strategy this is a huge story. And this is not any B-29, it is the one that dropped the first BOMB. If so you'd be leaving out a big part of the story. Could you display a B-29 as just a bomber as some have suggested, with 'no politics' maybe point out its long range, pressurized high altitude cabin, high speed or troubled engines. It is raised by the current site 'Ollie vs Smithsonian. This is just my opinion, but I think it is reasonable.
