05/31/2009. Produced for the well-known Jacqueline "Jackie" Cochran to enter the MacRobertson race from England to Australia, the two-seat Gamma 2G was the sole Gamma to be powered by the 700 hp Curtiss Conqueror SGV-1570F-4 twelve-cylinder liquid-cooled V-engine. Registered NC13761 the aircraft was flown for the first time on August 1, 1934. It was severely damaged when the delivery-pilot Wesley Smith made a forced landing (due to over-heated engine) on 30 September, 1934, and Cochran had to abandoned her plan to enter the MacRobertson race.
Being rebuilt, the aircraft was fitted with a 660 hp Pratt & Whitney R-1535-SA Twin Wasp fourteen-cylinder radial engine and reregistered NR13761, Jacqueline Cochran entered it in the 1935 Bendix Trophy Race, but did not finish to deteriorating weather. Subsequently the aircraft was leased to Howard Hughes who installed a 1,000 hp Wright SR-1820-G2 nine-cylinder radial engine, and set a new transcontinental nonstop record (Burbank to Newark) on January 13-14, 1936, in 9 hr 26 min 10 sec with an average speed of 259 mph (417 kmh).
Flown by Jackie, the aircraft was damaged beyond repair on July 10, 1936, when the aircraft ground-looped after an emergency landing due to engine failure; Jackie escaped injuries.
