Then came the Great War and with it galloping strides in aircraft development and flying skills. By the end of the war aircraft could fly higher and faster, were more reliable and their pilots more skilled. When the war was over there were hundreds of aeroplanes lying around that were no longer needed and that could be snapped up for peanuts by young daredevils who had caught the flying bug and weren’t very keen on spending the rest of their days working in an office. And so the flying circus was invented.
