The economy was clearly recovering by 1940, as farm and cattle prices rose. So did the price of oil. Massive Federal spending on infrastructure during the Depression was also beginning to show payoffs. Even before World War II broke out, the Oklahoma industrial economy saw increased demand for its products. The Federal government created such defense-related facilities as the Oklahoma Ordnance Works near Pryor, Oklahoma and the Douglas Aircraft plant adjacent to the Tulsa Municipal Airport. Numerous airbases dotted the map of Oklahoma. (See Oklahoma World War II Army Airfields).
