Following the interim period, Caledonian Airways (Prestwick) Ltd and British United Airways Ltd were merged into British Caledonian Airways Ltd (BCal). All former BUA aircraft were repainted adopting Caledonian's livery featuring a prominent Scottish Lion Rampant on its aircraft's fins. At that time, all aircraft were named after famous Scots and well-known Scottish places. This tradition was continued throughout the airline's 17-year existence. Some BCal aircraft were also allocated out-of-sequence registrations. (For instance, G-BCAL was allocated to one of the Boeing 707s, G-CLAN and G-SCOT were the registrations of the Piper Navajo Chieftains, G-DCIO was the registration of the eighth DC-10 and G-HUGE was the Boeing 747 Combi registration)
