Runway lights and an automated system that provides weather conditions was out of operation at Montgomery-Gibbs Executive Airport before a Cessna crashed into a San Diego neighborhood amid foggy conditions,

The runway lights were out, a weather alert system wasn’t working and there was heavy fog at a San Diego airport when a pilot who had flown across the country made the decision to proceed with landing but came up short and crashed into a neighborhood.

Investigators have revealed new details in the deadly San Diego plane crash, with the NTSB saying the airport's weather alert system and runway lights were not working.
