Very purposeful attack on the electrical system in california.
The attack on the PG&E facility targeted the sophisticated transformers that are at the backbone of the nation's electricity grid. The giant pieces of equipment are essential, costly and could take months to replace. Knock out enough of them, experts warn, and an entire region can be crippled for an extended period. They are also typically out in the open like sitting ducks.
On that April night, the attackers managed to disable 17 of them just by shooting through a chain-link fence. The bullet holes caused the transformers to leak thousands of gallons of oil, and ultimately overheat. Grid operators scrambled to reroute power from elsewhere to keep the system from collapse. The power stayed on, but just barely, because it happened during a time when demand for electricity was very low.
The bullet holes were carefully targeted so as not to hit the parts of the equipment that would cause an explosion and attract the attention of drivers on nearby U.S. 101. Of some 120 shots fired from at least 40 yards outside the fence, 110 of them hit transformers, Wellinghoff said.
Think I'll write my congressional representative about this issue.
