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.
