The Parks P-2 was powered by a 150 hp Axelson-Floco B engine and was designed and built at the St Louis based Parks Air College circa 1929. It was cancelled by the FAA on 13 August 1931. Parks used the name Parks Air Lines for a flight school, aircraft manufacturing operations and presumably displayed the name Parks Airport prominently on the hangar roof (background) at KSTL for publicity.

The P-1H was a 1932 variant of the Parks P-1/P-2, reverting to the P-1 designation perhaps because it was an entry-level model with a 100-hp Kinner K-5 radial. Dean Hammond of Ann Arbor, Michigan purchased the rights from the bankrupt Detroit Aircraft holding, and the designation officially changed to Hammond 100 as of January 1933. Seven examples were reportedly built, of which N15771 (c/n 204) was still airworthy in 2022. Photo from: Dan Shumaker collection

Flying over the campus of Parks College at KCPS. The school moved into St Louis in 1996. This Parks P-2A was manufactured here in 1929, although assembly was by Detroit Aircraft which marketed the P-2A as the Ryan Speedster for a while. During the 1960s this airframe was owned by modern barnstormer and writer Richard Bach. Photo by: Jim Schroeder / Saint Louis University

Sponsored by The Elks Magazine, four Studebaker President cars drove from NY to LA in 1929 and this plane, painted in the purple and white Elks colours, apparently made an associated "Coast to Coast Flight'. The P-2 was a development of the P-1 with an Axelson radial and top wing ailerons removed - similar changes as on the Fairchild KR-34 which was based on the same design. The P-2A version had a Wright J-6 Whirlwind. A lighter model of 1932 was the P-1H, powered by a 100-hp Kinner radial and produced by Hammond Aircraft as the Hammond 100 Sportster.

The Parks P-1 was a licensed copy of the Kreider-Reisner Challenger, which itself became the Fairchild KR-34. The P-1 retained the original WWI vintage OX-5 engine and 45 P-1s were built at Cahokia, across the Mississippi from Saint Louis. Oliver Parks founded Parks Air College here in 1927. Photo dated 'circa 1929'. NC353K was registered between 1929 and 1936. Photo from: Saint Louis University
