Having read all the 1819-1918 spec fi I could acquire, I have now fallen into a new reading habit: Popular Science Monthly magazine. It started by way of random research for 1934 and 1937 projects, especially once the first got rolled back to 1931.
Unlike, say, Popular Mechanix, PSM combine everything from articles on the early Rhine ESP studies to building ornate ship models. The covers represent everything from shipyards to air races, but the emphasis is on postulated vehicles — usually on the drawing boards, not often proven to work. But once they make PSM’s cover, they can live on in minds, just as the inventor envisaged them.
But what were they thinking to think of this?
