History
The airport opened on 8 October 1941 as Bennettsville Airport. It was renamed as Palmer Field in 1943 in honor of Capt. William White Palmer (1895-1934), Bennettsville native and World War I pilot. Palmer served in the 94th Aero Squadron in France during the war, shooting down three enemy aircraft. He was also awarded the Distinguished Service Cross and French Croix de Guerre for gallantry in aerial combat.

During World War II, United States Army Air Forces flying cadets were provided flight training under contract to Georgia Air Service, Inc & Southeastern Air Service, Inc., under the 53d Army Air Forces Flying Training Detachment (later 2152d Army Air Force Base Unit). The airfield was assigned to United States Army Air Forces East Coast Training Center (later Eastern Flying Training Command) as a primary (level 1) pilot training airfield. It had a 4,700' irregular all-direction turf field for landings and takeoffs. It may have had four auxiliary airfields, although none have been identified. Flying training was performed with Fairchild PT-19s as the primary trainer. It also had several PT-17 Stearmans assigned.

The airfield was inactivated on 16 October 1944 with the drawdown of AAFTC's pilot training program. It was declared surplus and turned over to the Army Corps of Engineers on 30 September 1945. It was eventually discharged to the War Assets Administration (WAA) and became a civil airport.
