Designed by Robert Edison Fulton Jr., it was an aluminum-bodied car, built with independent suspension, aircraft-sized wheels, and a six-cylinder 165 hp engine.

In December 1950, the Civil Aeronautics Administration (CAA) (later to become the FAA) certified one of the prototypes and gave it an 1A11 Aircraft Specification, N74104.

[2] The N74154 is the aircraft that is today in the main building of the National Air and Space Museum in Washington, DC, having previously been on display in the Steven F. Udvar-Hazy Center.

[5] In the mid-1990s, one of the surviving Airphibians was restored by Fulton III, along with David Dumas and Deborah Hanson.
