Deadly Alabama pipeline explosion

For the second time in two months, a pipeline that supplies gasoline to millions of people was shut down, raising the specter of another round of gas shortages and price increases. The disruption occurred when a track hoe — a machine used to remove dirt — struck the pipeline, ignited gasoline and caused an explosion Monday that sent flames and thick black smoke soaring over a forest in northern Alabama, Colonial Pipeline said. A September leak that spilled 252,000 to 336,000 gallons of gasoline occurred not far from the location of Monday’s explosion.
