It was crazy foggy in Palo Alto this morning and has been for the past of couple of mornings. I'm really surprised they tried to fly in those conditions.
The report suggests that the power outage in Palo Alto may have been caused by the plane crash. I find this hard to believe because the traffics lights were only down in the area near Stanford and downtown PA; as you drove closer to East Palo Alto, the lights were working. Of course maybe there was a larger outage earlier, and they just restored it in this pattern.
