While in Tucson, I just had to visit the Pima Air & Space Museum. They have a very extensive collection of mostly combat planes that I have ever seen. They have one of the very few remaining F-14s that are left. They had just about everything from the Wright Flyer:
I took the tram ride that took over an hour to listen to them talk about all the planes they had outdoors. Somehow, I was fascinated by the B-36. I can remember seeing one fly over the house where I grew up after WW II. It has a very distinctive sound. I walked around it and took pictures from every angle.
Probably the smallest flyable plane is the Bumble Bee.
