The model below takes some time to see what it is. I played with the picture to help visualize it. It has 11 hang-glider type wings, a tubular metal frame. The passenger compartment is in the lower middle area, looks like the pod below a blimp. The designer raised $200,000 (a hundred years ago) to make it work, but it never got off the ground.

The plane in the two pictures below is a seaplane. Actually, just a small boat with a high wing and one engine.

The next two pictures are plane-like kites, used to test new designs, before adding an engine and a pilot.

Below is the world's first drone attack vehicle. Used to bomb submarines.

Looking like an inter-galactic space vehicle, this blimp passenger cabin is being restored.

Engines !

The variety of propulsion engines over the last 100 years is equal to the variety of airframe designs. Piston engines (inline, radial, V-type, horizontally opposed) and gas turbines (ramjets, scramjets, thrust generators, shaft horsepower engines, turboprops, fanjets) of every size and shape. This museum had more than it's fair share of classice designs.
