Watch American Experience Season 29 Online

An account of an incident at a Titan II missile complex in Damascus, Ark., in 1980 that almost caused the explosion of a ballistic missile carrying a nuclear warhead 600 times more powerful than the bomb that destroyed Hiroshima. The near-calamity was kicked off when a socket fell from the wrench of an airman performing maintenance in a Titan II silo and punctured the missile, releasing a stream of highly explosive rocket fuel.
