The tiny Bede BD-5, restored by the museum and painted colors to match its "Octopussy" sibling. That movie featured the jet-powered BD-5J, whereas this has a pusher prop and an air-cooled, 650cc, two-cylinder engine that produced 55hp.
A few examples of some engines from the pre-jet age. On the left is a Wright R-1820 Cyclone 9-cylinder radial that developed over 1200hp. On the lower right is a 35hp Righter/Kiekhaefer O-45-35 two-cylinder used by the Navy for target drones. The big one in the back is a Pratt&Whitney R-4360 Wasp Major. It's got 28 cylinders and produced about 3,500 hp. This engine was used by a variety of big aircraft, including the B-36, which I saw at the incredible Pima Air and Space Museum.
This surprised me. It's an analog flight sim from before WWII. There are a few dozen level, and I just recently saw another one at a different small and not-well-known air museum: the Malta Aviation Museum.
