A little over 50 years ago a South Carolina doctor ... treated a family for injuries sustained when a sudden, inexplicable explosion tore through their backyard. The object in the 50-foot crater left behind their house was an atomic bomb that had fallen from a passing Air Force plane. The bomb had not been armed with its nuclear core; the blast came from the explosives intended to trigger a chain reaction. The crater can still be seen today. That incident, which led to an anti-nuclear movement in Britain, where the plane was bound, is one of many stories Eric Schlosser ... tells in Command and Control: Nuclear Weapons, the Damascus Accident, and the Illusion of Safety. During the cold war, nuclear bombs fell out of the sky, burned up in plane crashes and were lost at sea. In the incident Schlosser describes in greatest detail, the Damascus accident of Sept. 18, 1980, the warhead from a Titan II missile was ejected after a series of mishaps that began when a repairman dropped a socket wrench and pierced a fuel tank. Tactical nuclear weapons scattered across Europe had minimal security; misplaced tools and failed repairs triggered serious accidents; inadequate safety procedures and poor oversight led to dozens of close brushes with nuclear explosions. Schlossers readers (and he deserves a great many) will be struck by how frequently the people he cites attribute the absence of accidental explosions and nuclear war to divine intervention or sheer luck rather than to human wisdom and skill.
