Rosemead Airport is one of the vanished former airports which once were spread all throughout the Los Angeles metropolitan area. Western Air College operated the airport. The airport at this location in Rosemead was apparently built at some point between 1940–42, as it was not depicted on a 1940 LA street map. The earliest depiction of this airport was on a 1942 street map, which labeled the field as the Western Air College Airport. At some point between 1942-44 the airport was renamed Rosemead, as that is how it was labeled on the 1944 LA Sectional Aeronautical Chart (courtesy of John Voss). A flying school was also operated at Rosemead Airport.
