A landing ground known as Penston was used by the Royal Flying Corps during World War I. Subsequently, an adjacent site was developed as Macmerry airfield by the Edinburgh Flying Club, and this was used for scheduled flights by North Eastern Airways from 1936-39. In 1942 Macmerry was expanded to encompass the former Penston site. Civil flying ceased with the outbreak of World War II, and the airfield was taken over by the RAF as a satellite to the nearby fighter stationRAF Drem, although its role was soon expanded to other uses. From March 1941 until July 1943 a succession of RAF Army Cooperation Command squadrons were stationed at Macmerry using Blenheim, Lysander and Mustang aircraft. Part of No. 58 Operational Training Unit from RAF Grangemouth used Macmerry for fighter training until April 1942 when RAF Balado Bridge opened as a satellite to Grangemouth. Macmerry was also used as a satellite to the Operational Training Unit at RAF East Fortune - this was initially No. 60 OTU, and from November 1942 onwards No. 132 OTU. Other wartime activities at RAF Macmerry included a works operated by Cunliffe-Owen Aircraft for aircraft repair and modification; a training school for the RAF Regiment and an Elementary Gliding School. The airfield also continued to function as a satellite to RAF Drem, which had hosted a Royal NavyFleet Air Arm night fighter training school since October 1942. Naval use increased in December 1943 when 740 Naval Air Squadron formed at Macmerry, this being a communications squadron which used a variety of aircraft including the de Havilland Dominie, Avro Anson, Fairey Swordfish and Stinson Reliant. As the war in Europe drew to a close the need for home defence fighter stations declined, but the Fleet Air Arm needed more airfields to train aircrew for the war against Japan. Accordingly, both RAF Drem and RAF Macmerry were transferred to the Royal Navy as HMS Nighthawk and HMS Nighthawk II in April and June 1945 respectively. However, the end of the war curtailed the need for naval aircrews and RNAS Macmerry was handed back to the RAF in December 1945. Thereafter military use of RAF Macmerry was limited to the gliding school, which closed in 1946. In August 1946 the civil airfield was reopened by the Edinburgh Flying Club, but it closed in 1953.
