Vanguard costs pretty penny
In 1957, TCA places an order worth $67,000,000 for the British-made Vickers Vanguard, the big brother of the Viscount. This is the largest single-dollar order ever placed in postwar Britain. The Vanguard can fly on routes not suited to the shorter-range Viscount. By 1964, TCA has 23 of the aircraft in its fleet.
