One crazy fact is that the development of the B-29 (which dropped the atom bomb) was actually more expensive than the Manhattan Project itself

Truth. I mean, I had never heard of it. Sure, I knew that they used B-29s. But not that it was such a huge project.

And today there are only 2 flying B-29's left. (Until recently, there was only one.)
