This book captures the incredible 85+ year history of 1939 Spartan Executive serial number 17, currently registered as NC 17634. It is based on surviving records and numerous photographs that have been accumulated by the author over the past 18 years. The history begins in 1939 with the construction of the airplane in Tulsa, Oklahoma. After a brief corporate stint shuttling drilling executives around the oil fields of Oklahoma and Texas, the Spartan entered the wartime era where it first served as an advanced trainer for the British Government at Polaris Flight Academy before becoming a light transport/liaison aircraft in the Royal Air Force, registered as KD102. This book recounts the various noteworthy/famous military pilots who flew this airplane from late 1940 through the summer of 1945. After the war, it resumed the role as an executive transport in the oil industry for 11 years, before becoming a privately owned, multiple award winning, vintage show plane.
