British Overseas Airways Corporation
On 24 November 1939, BOAC was created by Act of Parliament to become the British state airline, formed from the merger of Imperial Airways and British Airways Ltd. The companies had been operating together since war was declared on 3 September 1939, when their operations were evacuated from the London area to Bristol. On 1 April 1940, BOAC started operations as a single company. Following the Fall of France (22 June 1940), BOAC aircraft kept wartime Britain connected with its colonies and the allied world, often under enemy fire, and initially with desperate shortages of long-range aircraft. During the war, the airline was sometimes loosely referred to as 'British Airways', and aircraft and equipment were marked with combinations of that title and/or the Speedbird symbol and/or the Union Flag.
British Caledonian in the 1970s
The creation of British Airways (BA) as a result of the 1974 BEA-BOAC merger came against the background of the first global oil crisis in the wake of the 1973 Arab-Israeli War, which led to the quadrupling of the price of a barrel of oil as a consequence of the decision by the Organization of Petroleum Exporting Countries (OPEC) to boycott the West in retaliation for its support of Israel during that war. This meant that the newly merged corporation's original revenue and profit projections were far too optimistic. During that time, BA began exerting pressure on the Government, at the time its sole owner as well as the regulator for all UK airlines, to curtail the activities of its independent competitors generally and of the "Second Force" in particular.
