British Airports Authority
The British Airports Authority was established by the Airport Authority Act 1965, to take responsibility for four state-owned airports from the Ministry of Aviation – Heathrow Airport, Gatwick Airport, Prestwick Airport and Stansted Airport. In the following few years, the authority acquired Edinburgh Airport (1971), Glasgow Airport (1975) and Aberdeen Airport (1975).
Subsequently privatised as BAA plc and later the airports were separated.
