On another thought, the "Duck and Cover" instructional videos or ideas don't make me think they were stupid or retarded. It was very practical... and I think it was just a way to keep everyone's spirits up, because somehow they knew the truth of the outcome. I find it sad, and I feel sorry for the people that had to live their lives in fear--so a silly turtle, I think, was well in order, even if it was false hope in the end.
Thats very accurate an assesment. In the UK/Europe, we had quite extensive experience of heavy bombing and mass destruction during the war years so cutesy cartoons and jingles wouldn't have cut the mustard over here. Instead we had very official and reassuring booklets and film reels showing how the civil defence would come forth from the bunkers and dig us out of our bomb craters. All very stiff upper lip, shipshape and Bristol fashion. Mostly nailing some doors against a wall and painting your windows white (As seen in the book/film "When the wind blows"). It was meant to offer practical advice that the common man could do himself without the money required building underground bunkers in your garden (The UK was bankrupted by the war).
In reality, there would be no prior warning of attack given by siren or radio because the panic this would have generated would have interfered with military and government efforts to respond to an attack.
As for the subject of how often we got close to pushing the red button, well I remember more than the one occasion being scrambled after being told "this is it" and the very long wait in our holding pattern over the North Sea waiting for further instructions. I'm getting chills down my spine right now with the memory.
I found a few clips relevant.
