Drones or their equivalent have long attracted political and military leaders dreaming of the surgical removal of their enemies. In 1812, the governor of Moscow, Count Rostopchin, devised a plan to get a hot-air balloon to hover over the French lines at Borodino and drop an explosive device on Napoleon. The source for this is the memoirs of the French writer, traveller and politician Chateaubriand and I have not read it anywhere else, but the story illustrates how, from the first moment man took to the air, he has seen it as a means of assassination.
