The Parks P-1 was a Curtiss OX-5-powered sport biplane that was built in the late 1920s.[1] Design and developmentBased in St.Louis, pilot, salesman and entrepreneur Oliver Parks founded an air school, airline and aircraft manufacturing business shortly after Lindbergh's 1927 transatlantic flight. Parks bought the rights to the Kreider-Reisner Challenger and modified it for production. The P-1 was built in a new facility in Cahokia, Illinois.[2] The P-1 was a tandem seat, open cockpit biplane with conventional landing gear. The fuselage was constructed of welded steel tubing with aircraft fabric covering. Operational historyThe P-1 was both sold as a commercial aircraft and placed into service as a trainer at Parks Air College. Although the OX-5 engine was out of production since 1917, there were still enough war surplus engines available at low enough cost to justify installing them on the 1929 design. This made the P-1 the last new aircraft produced using the outdated engine.[3] Parks located his engines by sending out his associate, Joeseph Wecker, to buy OX-5 engines from flight schools in the region. Production ended at number 45, before the onset of the Great Depression and the temporary takeover of the company by the Detroit Aircraft Corporation.[4] While part of the Detroit Aircraft Corporation, one experimental P-1 (X289W) was modified with a faired in, tail mounted, all-plane parachute. It was filmed in a live deployment for Paramount Sound News. The 60 ft diameter Russell parachute was designed to hold 2600 to 3000 lbs. A secondary 24 ft diameter parachute was installed for the pilot. One P-1 has been restored and displayed at the EAA airshow at Oshkosh, Wisconsin winning the award for outstanding open cockpit aircraft in 1992.[5] Variants
