The Shadow of the Airliner: Commercial Bombers and the Rhetorical Destruction of Britain, 1917-35

Abstract

Aerial bombardment was widely believed to pose an existential threat to Britain in the 1920s and 1930s. An important but neglected reason for this was the danger from civilian airliners converted into makeshift bombers, the so-called 'commercial bomber': an idea which arose in Britain late in the First World War. If true, this meant that even a disarmed Germany could potentially attack Britain with a large bomber force thanks to its successful civil aviation industry. By the early 1930s the commercial bomber concept appeared widely in British airpower discourse. Proponents of both disarmament and rearmament used, in different ways and with varying success, the threat of the commercial bomber to advance their respective causes. Despite the technical weakness of the arguments for convertibility, rhetoric about the commercial bomber subsided only after rearmament had begun in earnest in 1935 and they became irrelevant next to the growth in numbers of purpose-built bombers. While the commercial bomber was in fact a mirage, its effects on the disarmament and rearmament debates were real.
