The most famous example of the type of speculative but plausible science fiction that Campbell demanded from his writers is "Deadline," a short story by Cleve Cartmill that appeared during the wartime year of 1944, a year before the detonation of the first atomic bomb. As Ben Bova, Campbell's successor as editor at Analog, wrote, it "described the basic facts of how to build an atomic bomb. Cartmill and ... Campbell worked together on the story, drawing their scientific information from papers published in the technical journals before the war. To them, the mechanics of constructing a uranium-fission bomb seemed perfectly obvious." The FBI descended on Campbell's office after the story appeared in print and demanded that the issue be removed from the newsstands. Campbell convinced them that by removing the magazine "the FBI would be advertising to everyone that such a project existed and was aimed at developing nuclear weapons" and the demand was dropped.[16]
