I've written before about how the air defence problem seemed to inspire 'wildly creative' thinking in the early 20th century. Here are a couple more examples, submitted to the British government by members of the public, c. 1943 — the one effectively a form of death ray, the other a (technically) non-lethal weapon:
One of the most popular discarded suggestions was that the atmosphere should be flooded with carborundum powder which would be sucked into the fascist aero-engines and chew them to pieces. It is difficult to convince people that there is an awful lot of atmosphere!
Another one was that they should spread throughout the atmosphere 'a gas' (unknown to the suggestor — to be discovered by the chemist) which would congeal round the plane in flight, and when the crew baled out, would wrap itself around them so that they would arrive on the ground like chickens in gelatine. This was the solution of the paratroop problem!
The desire of these would-be inventors to help defend the nation (and perhaps profit handsomely) exceeded their knowledge of science and engineering.
The author of the article from which the above quotation is taken was Ritchie Calder, a former journalist then doing propaganda work for the Political Warfare Executive. Maybe that's how he came to be writing about the contributions of British scientists to the war effort for an American publication, Popular Astronomy:
Their maximum accuracy is in the air, in spite of three-dimensional fighting. When one hears of a thousand-plane raid being packed into fifty-five minutes over a single town in Germany, one should remember not only the vast ground organization, the transport supplies, the loading of the bombs, the timing of the take-off and returns, but also the intensive work of the scientists behind the operation.
But while Calder only deviates from such broad generalisations when poking fun at death rays and gelatin gases, this article does combine two things he was interested in: explaining science and defeating bombing. Before the war, Calder had been science editor for the News Chronicle; during the Blitz, he was a crusader for better post-raid welfare and shelter conditions. It's interesting that one of his sons, Nigel Calder, became a noted science journalist, while another, Angus Calder, became one of the most influential historians of the Blitz.
