"Let us take a hard look at the facts." With this direct and hardly reassuring sentence, the director of the Office of Civil and Defense Mobilization opened The Family Fallout Shelter, a 32-page manual published by the U.S. government in 1959 amid Cold War tensions. The document taught families how to build shelters capable of protecting them from radioactive fallout after a possible nuclear attack and, through technical drawings and sketches, outlined solutions using concrete blocks, walls filled with earth or sand, underground structures, and ventilation systems. It was a survival manual that, in many ways, also functioned as a construction manual.
