During the war, British aircraft production quickly expanded to be the largest industry in the country, involving hundreds of private firms and employing nearly two million workers.
[2] The department was formed in May 1940 by the Prime Minister, Winston Churchill, to produce large numbers of aircraft to fight the Battle of Britain.
The extra margin was added to provide an out-of-reach target to British industry so that it would push as hard as possible to increase production.
The ministry was characterised by, for its time, highly unorthodox methods of management, including its initial location at Beaverbrook's home, Stornoway House.
Personnel were recruited from outside the Air Ministry, interaction was informal, characterised by personal intervention, crisis management and application of willpower to improve output.
[2] Sir Stafford Cripps became the Minister of Aircraft Production on 22 November 1942, serving for two and a half years until the end of the war in Europe.
[10] He made a number of changes, including replacing unrealistic production targets, deliberately set too high to encourage effort, with realistic forecasts for each type of aircraft.
