Runway lights and an automated system that provides weather conditions were out of operation at Montgomery-Gibbs Executive Airport before a Cessna crashed into a San Diego neighborhood amid foggy conditions, killing all its passengers, investigators revealed Friday.

In the stillness of night, a quiet, tree-lined street in a San Diego neighborhood was plunged into chaos when a plane clipped a power line and crashed – turning cars into fireballs and sending residents fleeing in a haze of smoke and confusion.

Coroner's officials have identified more of the six people killed when a plane crashed into a San Diego military housing community last week.
