Back in the 1970s/early 80s,the BBC's World Service *had* to broadcast 
the Today show on its Radio 4 channel without fail every day, because the 
absence of that signal for just 2 days was understood by RN submarine 
commanders to trigger a flat-out nuclear strike against Russia. If the 
national grid went down, they had two standby 1MW diesel generators side-
by-side (just in case one failed) which could be fired up to get back on 
air again. I remember meeting the guy who's job it was to synch the 
gennies back and forth to the National Grid during power outages. He said 
it was the worst job in the world because of the danger involved (at all 
sorts of levels) if he got it just the tiniest bit wrong.
