Dense fog had rolled into the area around the time the plane was approaching the airport. Visibility was at half a mile at 3:55 a.m. and had dropped to a quarter of a mile just after 4 a.m. in the area around Marine Corps Air Station Miramar, which is just a few miles north of the crash site, according to the National Weather Service.

San Diego officials said at least two people are dead after the plane crashed in a neighborhood, causing multiple residences and cars to catch fire.
