A Year of Prophesying by H.G. Wells — Read

Bankrupt France and out-of-work England are developing a sort of armament race in air equipment. It has not quite the vigour of the old naval armament race; it is not so expensive, and the chances for financial and industrial loot are less. But it goes on, and at present, on paper at least, France leads handsomely. On paper France is ascendant over Britain in the air, capable of inflicting vast injuries, while sustaining small reprisals, and the matter is one of great concern to many anxious souls. They have visions of London stark and stiff and twisted under poison gas and all the British ports and docks destroyed.

The vagueness of our knowledge does on the whole enhance our terrors. But it is well to remember that our knowledge _is_ vague. It is particularly vague about the things that aeroplanes can carry and drop. Chemists and science students generally find an innocent pleasure in inventing wonderful rays, explosives, and lethal gases for the benefit of the ingenuous newspaper man. They invent them rather than make them. In practice the normal limitations and insufficiencies of this earthly life apply with peculiar force to explosives and lethal gases. Only in the world of scientific romance can they be made out of nothing and instantaneously. In this sordid world of everyday they demand ingredients that are difficult and expensive to produce and limited in amount, and they require apparatus and skill and often considerable courage for their preparation.
