Photo: ReutersA massive power outage threw San Francisco into chaos for most of the work day on Friday (local time), knocking out traffic signals, paralyzing businesses and halting the city's famed cable cars. The cause of the fire was a circuit breaker failure at the substation, PG&E spokesman Paul Doherty said. San Francisco International Airport remained operational, and a U.S. Department of Homeland Security spokesperson said there was no evidence of terrorism.
