How to Stop Worrying and Learn to Love the Bomb

In the early 1960s, the UK's Campaign for Nuclear Disarmament (CND) discovered that the government had -- unbeknownst to the British public -- built underground nuclear bunkers.
Known as Regional Seats of Government (RSG), these bomb-proof underground bunkers were scattered around the country and would have sheltered 'key' personnel. The RSG for central England, for instance, was buried under the village of Drakelow, near Kidderminster, Worcestershire. Quite who those key personnel were going to govern in the aftermath of a nuclear attack (would there be anyone left above ground?) was not spelt out.
That was then, this is now. Like to visit an RSG? You can! How about the biggest, deepest underground bunker open to the public? Details, here.
