By MATTHEW BROWN and GARANCE BURKE, Associated Press
SAN BRUNO, Calif. – First, the pipeline exploded. Then the flames, like a blowtorch, set the neighborhood overlooking San Francisco Bay ablaze.
Flaming chunks of asphalt hurled into the air from the blast blew through the roof at Bill Magoolaghan's house. As he watched from a nearby hillside in San Bruno, one question came to his mind: Why can't someone stop the tower of fire?
"The gas flames were still shooting 300 feet into the air," he recalled thinking, 40 minutes after the Sept. 9 explosion.
One reason is that the line was not equipped with remotely operated or automatic shut-off valves that would have halted the gas within minutes of the accident — devices that federal safety officials have recommended to industry and regulators for decades.
