Joyce Green, at Long Reach, near Dartford, was one of the first Royal Flying Corps (RFC) airfields. It was established in 1911 by Vickers Limited (the aircraft and weapons manufacturer) who used it as an airfield and testing ground. At the outbreak of World War I in 1914, the RFC followed and established a base. Subject to frequent flooding and a reputation as being unsuitable and too dangerous for training, it was eventually replaced by a more suitable site at RAF Biggin Hill.
