Development of the Hastings had been initiated during the Second World War in response to Air Staff Specification C.3/44, which sought a new large four-engined transport aircraft for the RAF. Early on, development of a civil-oriented derivative had been prioritised by the company, but this direction was reversed following an accident. On 7 May 1946, the first prototype conducted its maiden flight; testing revealed some unfavourable flight characteristics, which were successfully addressed via tail modifications. The type was rushed into service so that it could participate in the Berlin Airlift; reportedly, the fleet of 32 Hastings to be deployed during the RAF operation delivered a combined total of 55,000 tons (49,900 tonnes) of supplies to the city.
