What happens when the jets go overhead?

The jets bombed the city.

Perhaps the merest flourish of light and motion in the sky. Perhaps the bombs were there, and the jets, ten miles, five miles, one mile up, for the merest instant, like grain thrown over the heavens by a great sowing hand, and the bombs drifting with dreadful swiftness, yet sudden slowness, down upon the morning city they had left behind. The bombardment was to all intents and purposes finished, once the jets had sighted their target, alerted their bombardiers at five thousand miles an hour; as quick as the whisper of a scythe the war was finished. Once the bomb-release was yanked it was over.
