Aviation is flying. Naval aviation is when you land on or take of from a boat. In particular, it's when you take off from an aircraft carrier. There's also an exhibition about the Apollo program (take off from swamp, land in water), where the former naval aviator Neil Armstrong became the first man on the moon.
"I tested for the Air Force, and they said I could have this."
It looks like a mall ride, or alternatively the short yellow bus for combat pilots, but is actually a very successful flight simulator called the Link Trainer[c]. Created by Ed Link and manufactured by his company Link Aviation Devices, it was used from the mid-1930s to the late 1950s to train pilots in instrument flying - that is, when you don't get to look outside while flying because it's too dark, or too cloudy, or some other reason that makes it impossible to look out the window and figure out where you are and where you are pointing the aircraft. During World War II, the United States could churn out combat aircraft like no other nation. Having a cheap and safe way to teach the basics of instrument flying was certainly a boost, making "production" of pilots that much more efficient.
This was the funniest bit of the museum. The pod seen here is mounted on an arm that gives it the ability to spin around the pitch and roll axis. Couple that with 3d-glasses, a good joystick, and the minutes (I think it was three) you get will pass by in no time at all.
