the largest airport in Britain and the busiest airport for international flights in the world. It is 15 miles/24 kilometres west of London and was opened in 1946. By 1961 it had three terminals (= buildings for arrival and departure) and a fourth opened in 1986. A fifth opened in 2008, though many people are unhappy about the increased number of flights and passengers this creates.
