Churchill obviously foresaw the threat of the Nazis very early but he was not in power.Chamberlain poured money into a succession of 13 RAF expansion programmes, while, as prime minister, he approved the construction of a series of aircraft factories, most notably the world’s largest plant at Castle Bromwich in Birmingham, which was meant to produce 1,000 Spitfires by June 1940. By 1939, rearmament was swallowing 21.4 per cent of Britain’s gross national product, a figure that reached 51.7 per cent by 1940. When Chamberlain finally declared war in September 1939, Britain’s aircraft output had overtaken that of Germany’s.
