During the 20th century, and particularly since 1939 and the outbreak of the 2nd World War, airfields have become a feature of low-lying landscapes. Both commercial and military airfields, airstrips and associated buildings are recorded, including the housing estates built for air force personnel.
Many military airfields have been abandoned, and are now rough grazing or farmland. Some have become industrial areas, while one or two are now golf courses or visitor attractions.
The main runway and associated buildings at Dundee Airport lie alongside the River Tay. Airfields such as this are noted on current OS maps as well as in aerial photographs, which record those abandoned after the 2nd World War.
