The NTSB says the pilot didn't report any problems or declare an emergency before Thursday's deadly San Diego plane crash.

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.

Aid group San Diego Humane Society is supporting animals affected by Thursday's plane crash in a San Diego neighborhood. Rescue teams have provided lost animals shelter, medical attention and decontaminated dogs exposed to jet fuel.

All six people aboard a small plane that crashed in a San Diego neighborhood were killed, but nobody on the ground was seriously injured, an official for the National Transportation Safety Board confirmed on Friday,
