Washington D.C.

Here are some of the older engines.

Here's an ancient Liberty engine (circa 1917) and a newer Pratt & Whitney Wasp engine (circa 1925).

A Wright Whirlwind engine (circa 1927) and a Pratt & Whitney Twin Wasp engine (circa 1937).

Lastly, the Wright R-3350 Turbo-Cyclone 18 engine. Yowza, this one is packing 18 cylinders and roars with 3,400 horsepower. The names of all these engines are kinda silly; Wasp, Whirlwind, Cyclone. If I worked for an aircraft engine manufacturor in their marketing department, I'd propose the name of "XP-40 Quad-Turbo Tornado-Supercharged Bumble Bee". Pretty catchy, eh?

A variety of planes are hanging from the rafters.
