Flash over Phoenix came from breaker

PHOENIX, March 13 (UPI) -- An Arizona utility provider said the flash of light that lit up the sky over Phoenix came from an opened breaker on an electrical line.

Arizona Public Service confirmed the theory, which was first put forward by Phoenix Fire Arson Investigator Steve Franklin, KSAZ-TV, Phoenix, reported Tuesday.

APS said the flash, which happened early Thursday morning and was seen by viewers of the "Arizona Morning" show on KSAZ-TV, was not traced back to the breaker until an employee came forward during the weekend and told officials about a call involving a breaker opening near 35th Avenue and Cheryl.

The utility provider said power went out for some customers for only a few seconds and no equipment was damaged.
