After World War II, Heinlein tells us, he resumed writing with two objectives: “first to explain the meaning of atomic weapons through popular articles… I wrote nine articles intending to shed light on the post Hiroshima age, and I never worked harder on any writing, researched the background more thoroughly, tried harder to make the (grim and horrid) message entertaining and reasonable…I continued to write those articles until the U.S.S.R. rejected the United States’ proposals for controlling and outlawing atomic weapons… and I stopped trying to pedal articles based on tying down the Bomb… –Was I really so naif that I though I could change the course of history this way? No, not really. But damn it, I had to try!” Heinlein referred to these articles as his “failing at World Saving.” Recently, Ed Wysocki wrote, for the The Heinlein Journal, an article about one of these attempts, entitled “Flight Into the Future.” By special arrangement with the author and the Journal, this paper is republished here. This is especially significant because it is the only one of Heinlein’s cautionary articles written after World War II that he was able to get published.
