The San Diego plane crash that killed at least four people and injured several others on Thursday involved a Cessna 550 private jet. The crash took place around 3:45 a.m. in the Murphy Canyon military housing neighborhood.

The identities of all six passengers who died after a plane crashed into a San Diego neighborhood earlier this week have been revealed.

Investigators are examining whether foggy conditions and technical glitches at a San Diego airport that cut off lights meant to guide pilots may have played a role in a fatal plane crash.
