Onlookers watch flames shoot high in the air from a freight train hauling ethanol that derailed early Wednesday in Columbus, Ohio, leading to spectacular explosions that were felt for blocks. The scene was dramatic as three tank cars each carrying 30,000 gallons of ethanol burned through the night. The derailment occurred about 2 a.m. on the Norfolk Southern Corp. tracks in an industrial area of the city. Nobody aboard the train was injured. People living in a 1-mile radius were evacuated for several hours. The National Transportation Safety Board dispatched a 10-person team to investigate.
