The book, Air Force Colors Vol. 1 1926-1942 represents the first in a multiple volume series that begins a pictorial study of United States Military aircraft color schemes from 1926 through mid 1942. The 1926 to 1942 timeframe saw a remarkable growth and development of United States Military aviation, which is reflected in the changing markings and colors used on aircraft from this era. This book chronicles the changes in aircraft, camouflage, organizational structure, painting schemes and squadron / unit insignia that took place between 1926 and mid 1942. While initially after World War I aircraft and personnel were reduced to a fraction of their wartime levels, a gradual modernization program was put in place after 1926 that increased the number of squadrons and personnel in the United States Army Air Force. Although the capabilities of the Untied States Army Air Force were much improved on the eve of World War II, when war finally engulfed America after the Japanese attack on Pearl Harbor Hawaii on December 7, 1941, a "crash" manufacturing program was undertaken to put aircraft production on a war footing. The color schemes and markings from mid 1942 until the formation of the independent United States Air Force are the subject of Volume 2 of this series.
