A handful of trouble makers could plunge America into darkness

As few as nine teams... maybe even just nine determined people... could have the potential to plunge America into a nation-wide blackout.

So reports the Wall Street Journal:

The U.S. could suffer a coast-to-coast blackout if saboteurs knocked out just nine of the country's 55,000 electric-transmission substations on a scorching summer day, according to a previously unreported federal analysis.

Still think "preppers" are nutty-kooky when they talk about stuff like a national grid collapse? Even the top people in government say the same sort of things, but - more often than not - they tend to keep it to themselves.
