May 20, 1918

President Woodrow Wilson signs the Overman Act, which, mostly as a result of the monumental problems the US faced in gearing up aircraft production for World War I, transfers the Aviation Section from the Signal Corps to two agencies under the Secretary of War-the Bureau of Aircraft Production and the Division of Military Aeronautics, which constitutes the US Air Service. Maj. Gen. William L. Kenly is named as the Air Service’s director of Military Aeronautics.
