RAF Coningsby — Lincoln, Lincolnshire, United Kingdom

QCY denotes RAF Coningsby, a Royal Air Force station in Lincolnshire, England, best known as home to the Battle of Britain Memorial Flight, which maintains historic aircraft including Spitfires and Hurricanes for commemorative flypasts. As an active military base rather than a civilian airport, QCY has also served as a front-line station for Royal Air Force fighter squadrons, including Typhoon aircraft used for national air defense. It is not open to scheduled commercial air travel, and the surrounding Lincolnshire countryside hosts several other RAF installations reflecting the county's long aviation heritage dating back to both World Wars. Public access is generally limited to organized events or the Battle of Britain Memorial Flight visitor center.
