The talk will show how detailed computer models were used to reconstruct the history of the airport from archive maps and photographs. The development of Croydon Airport will be covered from the RFC airfield on Plough Lane, the RAF development in 1918, the Civil airport in 1920 and finally the new airport in 1928. A selection of aircraft and airline history will be included, and also the development of facilities such as Radio, Air Traffic Control, the Met Office and Customs.   The talk will be given by Roger Potten, Historic Croydon Airport Trust.
