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.

The music agency Sound Talent Group said that three of its employees died on the private plane that crashed into the Murphy Canyon neighborhood.

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.
