The first three chapters of The War in the Air relate details of the life of Bert Smallways and his extended family in Bun Hill - a (fictional) former Kentish village which had become a London suburb within living memory (in many ways similar to Bromley where Wells was born). The story begins with Bert's brother Tom, a stolid greengrocer who views technological progress with suspicion and apprehension (which would turn out to be all too well founded) and their aged father, who recalls with longing the time when Bun Hill was a quiet village and he had driven the local squire's carriage. However, the story soon focuses on Bert who is an unimpressive, not particularly gifted, unsuccessful young man with few ideas about larger things - but far from unintelligent. He has a strong attachment to a young woman named Edna, and works as a helper and later a partner in a bicycle shop. When bankruptcy threatens one summer, he and his partner abandon the shop, devise a singing act ("the Desert Dervishes"), and resolve to try their fortunes in English sea resorts. As chance would have, their initial performance is interrupted by a balloon which lands on the beach before them, and which turns out to contain one Mr. Butteridge. Butteridge is famous for his successful invention of an easily manoeuvrable fixed-wing aircraft whose secret he has not revealed and that he is seeking to sell to the British government or, failing that, to Germany. Prior to Butteridge, nobody had succeeded in producing a practical heavier-than-air machine, only a few awkward devices of limited utility such as the German "Drachenflieger", which had to be towed aloft and released from an airship. Butteridge's invention is a major breakthrough, as it is highly manoeuvrable, capable of both very fast and very slow flight, and requires only a small area to take off and land, reminiscent of the later autogyro. By accident Bert is carried off in Butteridge's balloon, and discovers Butteridge's secret plans on board it. Bert is clever enough to appraise his situation, and when the balloon is shot down in a secret German "aeronautic park east of Hamburg," Bert intends to pass himself off as Butteridge to sell the secret. However, he has stumbled upon the German air fleet just as it is about to launch a surprise attack on the United States - and Prince Karl Albert, the author and leader of this plan, decides to take him along for the campaign. The Prince, world-famous as "The German Alexander" or Napoleon, is a living manifestation of German Nationalism and boundless imperial ambitions, his personality as depicted by Wells in some ways resembling that of Kaiser Wilhelm II. Bert's disguise is soon seen through by the Germans, and - narrowly avoiding being summarily thrown overboard by the furious Prince - he is relegated to the role of a witness to the true horror of war.
