 Security Airster S1-B

The Security Airster is a two-seat single-engine monoplane designed by Bert Kinner and built by his Security National Aircraft Corporation which later became the American Aircraft Corporation.

This is the open cockpit S-1A model. The museum owns the rare sliding canopy model S-1B

The Airster came on the aeronautical scene in 1933. The museum display aircraft is from 1940. It is a low-wing braced design with folding wings and a fixed landing gear. It is powered by a five cylinder radial engine of 125 HP designated as the S5-125. Economic times were difficult and resulted in only 5 of this particular model being built.
