Chance Vought V - 173

One of the most unusual aircraft ever designed for the U.S. Navy was the Chance Vought V-173, also known as the Zimmerman
"Flying Pancake". It was a prototype "proof of concept" aircraft that lacked wings, instead relying on its flat circular body to provide
the lifting surface. This multi-million dollar project nearly became the first V/STOL (vertical takeoff and landing) fighter. The V-173
blueprints were shown to the Navy in 1939, with wind tunnel tests on full scale models being done in 1940-41. Flight testing of the
V-173 went on through 1942 and 1943, resulting in reports of "flying saucers" from surprised Connecticut locals.
The V-173 prototype was saved and was given to the Smithsonian.
