Produced for the PBS series American Experience, this hair-raising documentary revisits the 1980 accident in which the fuel tank of a U.S. nuclear missile in Damascus, Arkansas, was ruptured and the fuel ultimately ignited. Director Robert Kenner interviews the former U.S. Air Force technician who, having chosen the wrong wrench, dropped a six-pound bolt down the silo of a Titan II missile and punctured the tank. Denial turned to panic as the crew realized they were facing a nuclear catastrophe, though when the fuel exploded eight hours later, the missile warhead landed on the ground without detonating. Adapted from a book by Eric Schlosser (Fast Food Nation), the documentary periodically departs from the tense narrative in Damascus to review the proliferation of nuclear missiles during the Cold War and to replay other close calls in our nuclear-defense history, most notably the 1961 crash of a B-52 bomber in Goldsboro, North Carolina. The inescapable conclusion is that we have more to fear from our own human error than from our enemies’ malevolence.
