A San Bruno neighborhood was devastated by an uncontrollable fire last night when a PG&E pipeline exploded at 6:24 pm. The explosion, which left behind a 30-foot-wide crater, has so far killed 4 and injured more than 50 while destroying more than 30 homes. The damage has been so bad that Lt. Gov. Abel Maldonado (who is acting as Governor as Arnold Schwarzenegger is in Asia) has declared a state of emergency in San Bruno.
