I've been to the USAF Museum in Dayton, Ohio, where they have the B-29 that dropped the bomb on Nagasaki.
At first glance, it's just another plane in the museum. But if you actually let yourself think about it, it's somewhat more sobering: you're looking at the actual plane that actually flew and did it. It really brings home the reality of it. And it's a bit disturbing to think that a piece of machinery can end the lives of tens of thousands of people all at once, and that humans are even capable of building such things.

Anyway just thought I'd share my experience.
