Anderson air raid shelters?

There is one in our museum in a permanent wartime exhibition of the war things you speak about. I can remember us having one in our garden when I was a small boy.

Sorry, I can't answer about the UK, but there was recently an article in the New York Times indicating that there are at least two people in New York City who still receive small property-tax reductions for having cold-war-era bomb shelters underneath their houses.

There have been none , aircraft were zeppelins were slow and ineffective and almost a shaggy dog story.Besides for the very few small bombs they dropped most humans didn't recognize they existed.
