The Vickers Vanguard was a British short/medium-range turboprop airliner introduced in 1959 by Vickers-Armstrongs, a development of their successful Viscount design with considerably more internal room. The Vanguard was introduced just before the first of the large jet-powered airliners, and was largely ignored by the market. Only 44 were built, ordered by Trans-Canada Air Lines (TCA) and British European Airways (BEA). (Source Wikipedia)
