DC Adventure :: Smithsonian - Air & Space

This museum had lots of artillery including missiles, attack planes, and different types of bullets. The biggest one I saw was four inches long.

I got to work the controls of a battleship. It didn't really do anything. It looked more complicated than a modern one would look like.

They also had this station where you sit on a spinning tool and held a bicylce wheel and someone spun it and when I turned the wheel, I turned on my stool without having to move myself.

Compared to all the other planets, Saturn was bigger  than I thought - almost as big as Jupiter, bigger counting the rings.
