In March of 2005, the BP Refinery in Texas City, Texas, suffered a series of explosions that decimated a large portion of the facility and killed 15 workers. Examine the series of events that led to one of the worst industrial accidents in the United States. Then we’ll document the unusual circumstances that caused American Airlines flight 587 to fall from the sky. What happened in Times Beach, Missouri, when a local waste hauler oiled down dusty roads with oil that was laced with dioxin? Next we’ll look at what went wrong with NASA’s Skylab in 1974 and finally we’ll examine the fire that destroyed the gas company, Praxair, in June of 2005. Interviews with survivors help complete the picture.
