Beaumont Sur Oise was a pre-World War II French Air Force airfield with a 5,000-foot (1,500 m) concrete runway (05/23).
Later, in November and December 1943, Schlachtgeschwader 4 (SLG 4) operated Focke-Wulf Fw 190F/Gs as a ground-attack unit.
Fortunately, little battle damage was sustained, and the airport became a USAAF Ninth Air Force combat airfield, designated as "A-60" about 26 September.
[6][7] Under American control, the Ninth Air Force assigned the 386th Bombardment Group to the airport which flew B-26 Marauder medium bombers from the facility between 2 October 1944 and 9 April 1945.
The wartime concrete runway remains in a field complete with many patches of bomb craters, connected to what appears to be the prewar French air base.
