An Aircraft Production Board was set up under the chairmanship of an automobile manufacturer, Howard E. Coffin of the Hudson Motor Car Company, but the airplane of World War I was not suitable to the mass-production methods of automobile manufacturing and Coffin neglected the priority of mass-producing spare parts. Though individual areas within the industry responded well—particularly in engine production, with the development of the Liberty engine, of which 13,500 were produced—the industry as a whole failed. Attempts to mass-produce European models under license in the U.S. were largely failures. Among pursuit planes, the SPAD S.VII could not be engineered to accept an American engine and the Bristol F.2 became dangerous to fly using one.
