British United Airways (BUA) was a private, independent British airline founded in 1960. Gatwick became BUA’s main operating base while Stansted was the main base for trooping flights until 1964.  An order for ten BAC One-Eleven jet aircraft in May 1961 launched BUA’s fleet re-equipment programme in support of its long-term policy to develop primarily as a scheduled airline. In 1969 BUA had 4 Vickers VC-10 jets and 9 BAC 1-11s. BUA merged with British Caledonian in 1970
