re: #74 andres

Now that you mention it… I remember seeing a round plane in the Dallas Frontiers of Flight Museum…

IIRC, it was canned because jets were invented shortly after they were experimenting with it.

Vought V-173 “Flying Pancake”

The developmental V-173 made its last flight 31 March 1947. In 131.8 hours of flying over 190 flights, Zimmerman’s theory of a near-vertical takeoff- and landing-capable fighter had been proven.[8] The V-173 is now part of the Smithsonian collection at the Paul E. Garber Preservation, Restoration, and Storage Facility in Silver Hill, Maryland. It is currently at the Vought Aircraft plant in Grand Prairie, Texas being restored to go back on display.
