      SAN BRUNO, Calif. (AP) - A massive fire is roaring through a mostly residential neighborhood in the San Francisco suburb of San Bruno.
      Firefighters from San Bruno and surrounding cities are battling the blaze that started on a hillside and is now consuming homes in a residential neighborhood.
      A South San Francisco fire official confirmed earlier that firefighters were responding to a fire, but had no other details.
      Witnesses say a loud explosion was felt just before the flames erupted around 6 p.m. Thursday.
      The fire is burning in a mostly residential area a few miles from San Francisco International Air, but the Federal Aviation Administration and a spokesman for the airport say they have no record of a plane crash.
