Call Logs Show PG&E Scrambled Minutes Prior to San Bruno

New call logs from a California pipeline explosion that killed eight people show that utility crews were scrambling to stop gas pressure surges and feared they would cause a "major, major problem."
       
The records show that shortly before the September blast in San Bruno, Pacific Gas & Electric Co. operators knew a botched repair job at a control station was allowing gas to flow unabated. They were powerless to fix the problem remotely.

 One operator said, "We're screwed, we're screwed."      

A half-hour later, a fireball ignited about 30 miles northwest of that control station. It killed eight people and destroyed dozens of homes in a San Francisco Bay neighborhood.
       
The call logs are among the documents released by the Nationa Transportation Safety Board last week. The agency is still probing what caused the explosion.
