Curtiss Condor NC727K belonging to Atlantic flyer Clarence Chamberlin and possibly the aircraft he used to barnstorm the Mid West. This 91ft 8in span 18-passenger variant of the US Army Condor bomber was powered by two 12-cylinder 600 h.p. Curtiss Conqueror engines. The Condor had an all-up weight of nearly 18,000lb and was certificated in 1929.
Stinson SR-9 NC2285 at Springfield Airport. The 1937 version of thus well-tried five-seater came in either De Luxe ("D") series or Multi-Purpose (“M”), the former for the private owner and sportsman pilot and the latter for general transport duties. Variants were powered by the Wright Whirlwind (285-320 h.p.), the 450 h.p. Pratt & Whitney Wasp Junior, and the 245 h.p. Lycoming nine-cylinder R-680-D6 engine. Fitted with the Lycoming, the SR-9BD cruised at around 140 m.p.h. and had a range of 400 miles.
Travel Air 6000-B NC624K of Inter City Airline, a commuter airline operating out of Springfield Airport. The Travel Air S-6000-B was powered by a 300 h.p. Wright J6 engine and was certificated in March 1929. Around 55 of these six-seat aircraft were built by the company at its Wichita, Kansas factory. Jean Louis Drapeau photograph.
Stearman 4-CM-1 SR Speedmail mailplane NC13905 owned by Rostell Wheeler, who was probably the first black pilot in Massachusetts. The type was certificated in May 1930 and around 15 CM-1s were built at Wichita, Kansas.
Curtiss Robin NC99M, owned by Gulf Aviation Fuel and advertising No-Nox motor fuel, during a visit to Springfield Airport. The Curtiss Robertson Robin Airplane Manufacturing Company was formed in 1928 as a subsidiary of the Curtiss-Wright Corporation to undertake production of the three-seat Robin. During 1929 and 1930 a Curtiss Challenger Robin twice broke the world endurance record. In August 1930 a Robin flown by Dale Jackson and Forrest O'Brine stayed aloft for nearly 27 days. Later, a four-seat Robin, the 4C-1A, was introduced, fitted with a 185 h.p. Curtiss Challenger radial engine. Many other variants of this prolific aircraft were produced before production ceased in late 1930.
Sikorsky S-39C NC833W photographed on a visit to Springfield. This five-seat amphibian was powered by a single 300 h.p. Wasp Junior. It was certificated in 1930 and was built at Bridgeport, Connecticut by the Sikorsky Aircraft Corporation, a Division of the United Aircraft Manufacturing Corporation. The 52ft span S-39 cruised at 100 m.p.h. and weighed 4,000lb fully loaded. The S-39 was derived from the twin-engined S-38, a much larger amphibian that carried up to nine passengers.
