Kinner Airplane and Motor Corp., Security Aircraft Corp., and Security National Aircraft Corp. The Security National Aircraft Corporation (1933) and Security Aircraft Corporation (1937) originated from the Kinner Airplane & Motor Corporation. Winfield Bertram “Bert” Kinner founded the company in 1919 to produce radial engines as well as light general and sports aircraft. He made a name for himself as a knowledgeable aircraft and engine manufacturer.

In 1922, the city of Glendale, CA bought 33 acres adjacent to the Southern Pacific RR tracks and cleared a 1200-foot runway for the Glendale Municipal Airport. Opened in March 1923, this was considered the first paved runway of the western United States. The first hangar built there was for the ‘Kinner Airplane & Motor Corporation.’ The company was most notable for the development of the first five cylinder-radial type airplane motor. This very engine powered many early biplanes of the 30’s as well as the very well-known Ryan PT-22 USAF trainer during the 40’s.

Amelia Earhart first learned to fly at the Kinner airfield in an OX-5 Canuck. Surprisingly enough, her instructor was a woman. Amelia hired Anita “Neta” or “Snooky” Snook for $500 for the first 12 hours of instruction, only taking another three before she was ready for her solo. Neta Snook was the first woman to own her own aviation business carrying passengers, designing aerial advertisments, and commercial instruction. On July 24th, 1922, Amelia’s 25th birthday, she purchased the prototype Kinner Airster for $2,000 and later named her plane the Kinner Canary. Her plane was designed and built right at the Kinner Airfield in Glendale. Gaining most of her experience in her first aircraft, Amelia went on to bigger and better events marked forever in history.

Although, Kinner went bankrupt in 1937 selling his aircraft rights to Timm Aircraft and engine rights to a new Kinner Motors. The founder of Timm Aircraft, Otto William “Barnstormer” Timm actually gave Charles Lindbergh his first airplane ride. The new Kinner Motors company produced thousands of engines for trainers during World War II. Later reorganized in 1946, Kinner Motor, Inc. was sold off to Gladden Products, a manufacturer of motor scooters.

The earliest Kinner planes were biplane designs, but Kinner eventually settled onto a low-wing design that had a relatively long run, and more importantly served as the model and inspiration for several other aircraft makes through the late 20’s and into the 50’s. Kinner died in 1958. Read more at https://en.wikipedia.org/wiki/Kinner_Airplane_%26_Motor_Corporation
