Doolittle left Army Air Corps (as the Air Force was known prior to being established as a separate branch in 1947) active service in 1930, though he remained active as a Reserve officer. Working in private industry, he was instrumental in improving aviation fuels and became the president of the [[Institute of Aeronautical Science]] in 1940. In July of that year, he returned to active duty with the Air Corps, subsequently working to convert the automobile industry to military production.
