A utility worker doing maintenance near Yuma, Ariz., triggered a massive blackout that jammed roads, closed schools and businesses, grounded planes and left more than 4 million people across a large swath of Southern California and Mexico without power.
The blackout Thursday brought routine life to a halt. Many offices closed, but workers endured gridlock getting home because traffic lights were out. Officials said they noticed an increase in fender-benders in some areas as drivers tried to navigate the roads.
People were trapped in elevators and on rides at Sea World in San Diego and Legoland in Carlsbad. Hospital emergency rooms switched to backup generators, while outgoing flights from San Diego were canceled for several hours.

"The outage appears to be related to a procedure an APS employee was carrying out in the North Gila substation," an APS spokesman said in a statement. "Operating and protection protocols typically would have isolated the resulting outage to the Yuma area. The reason that did not occur in this case will be the focal point of the investigation into the event, which already is underway."
