The history of Buchanan Field Airport, also known as Concord Airport, dates back to the World War II era where a training facility was needed for pilots of the unique Aircobra P-39 aircraft. Concord fit the bill for Bay Area needs as the weather and fog-free conditions made it most appealing. Following the end of the war, the airport was returned to the County of Contra Costa for public use and the airport was officially named Buchanan Field – after Supervisor William J. Buchanan, who served on the board for over 40 years. Over time several improvements were added to increase the utility of the airport. Some of the airport improvements included runway lighting and an operating control tower. During the Korean War, troops were flown out of Buchanan Field to/from Stoneman Base, located in Pittsburg, CA – which is adjacent to the airport. In the 1950’s, Stoneman Base was a bustling training facility. Needless to say the presence of Buchanan field aided the wartime efforts in many facets that most locals are unaware of.
