I know we all have moans about how one aspect or another doesn't work quite as well as it should but on the whole, isn't it amazing that "we" have systems that work almost all of the time and can respond quickly when needed in an emergency, often without the public even being aware what's going on.
The organisation and detail behind some of the emergency plans is mind blowing IMO.
Which is a very good thing because it's also terrifying to think how bad things would be if some of these aspects failed for any period of time.
