Beijing Airport was opened on 1 March 1958. The airport then consisted of one small terminal building, which still stands to this day, apparently for the use of VIPs and charter flights, along with a single 2,500-metre runway on the east which was extended to 3,200 metres in 1966 and 3,800 metres in 1982 respectively. Another 3,200-meter runway on the west was completed in October 1978. On 1 January 1980, a newer, larger Terminal 1 – green in color – opened, with docks for 10 to 12 aircraft. The terminal was larger than the one built in the 1950s, but by the mid-1990s, its size became relatively inadequate.
