The Aviation Section, Signal Corps was created by the Act of 18 July 1914, Chapter 186 (Public Law 143, 63rd Congress), 38 Stat. 514, to supersede the Aeronautical Division, an administrative creation of the Signal Corps within the Office of the Chief Signal Officer (OCSO), as the primary agency for military aviation. Earlier legislation to make the aviation service independent from the Signal Corps died in committee after all officers connected with aviation save one, Captain Paul W. Beck, testified against it. Later provisions of the National Defense Act (39 Stat. 174), 3 June 1916, and the Aviation Act (40 Stat. 243), 24 July 1917, permitted aviation support functions to be gradually transferred from the Aeronautical Division to newly established aviation section organizations. The new law established the purpose and duties of the section, authorized a significant increase in size of U.S. military aviation to 60 officers and 260 enlisted men, increased the size of the Signal Corps by an equal number of personnel to provide them, stipulated that pilots be volunteers from branches of the line of the Army, and detailed them for four years. The Aeronautical Division then became the administrative component of the Aviation Section until its abolition in 1918. The first funding appropriation for the Aviation Section was $250,000 for fiscal year 1915.
