Investigators are still trying to determine the cause of a San Diego plane crash that left at least three people dead and several others injured in the military housing neighborhood of Murphy Canyon on Thursday.

At least three people were killed when a private jet crashed into a San Diego neighborhood Thursday morning, adding to the long list of aviation disasters this year.

The airport also had filed a notice to pilots called a Notam, informing them that one of the runways had experienced an issue with the lighting system that guides landing planes.
