In February 1940 at Wright Field, the Army Air Corps established the Technical Data Branch (Technical Data Section in July 1941, Technical Data Laboratory in 1942). After Air Corps Ferrying Command was established on 29 May 1941, on 21 June an installation point of the command opened at Patterson Field. The Flight Test Training unit of Air Technical Command was established at Wright Field on 9 September 1944 (moved to Patterson Field in 1946, Edwards AFB on 4 February 1951). Two densely populated housing and service areas across Highway 444, Wood City and Skyway Park, were geographically separated from the central core of Patterson Field and developed almost self-sufficient community status. (Wood City was acquired in 1924 as part of the original donation of land to the government but was used primarily as just a radio range until World War II. Skyway Park was acquired in 1943.) They supported the vast numbers of recruits who enlisted and were trained at the two fields as well as thousands of civilian laborers, especially single women recruited to work at the depot. Skyway Park was demolished after the war. Wood City was eventually transformed into Kittyhawk Center, the base's modern commercial and recreation center.
