Web Site History and Future

This site was created in 2001 and contained just a few pages about the public warning system. Since then its grown to 30 Pages thanks to a lot of helpful feedback and encouragement from so many people able to plug the holes in my knowledge. I am always pleased to receive all kinds of information and to hear of your experiences related to the topics on this site as there are still pieces of the jigsaw missing

Are you holding a piece of the jigsaw ?

Many of us signed the Official Secrets Act, this protected information for 30 years, so anything pre-1985 is now open. The National Archives in Kew have files previously classified Secret open to public inspection which form the basis for a number of pages on this website. The Freedom of Information Act, has opened younger files too.

There are still a few of foggy areas where your knowledge may help provide a better understanding. Please click the link below to see the burning issues.

Issues to be Resolved

Steve Scanlon - The Web Site Owner

I became interested in the UK Civil Defence for the Cold War, as a result of working as a engineer for 'Post Office Telephones' later privatised and renamed 'British Telecom'. Between 1978 and 1981 I maintained the early warning equipment and visited ROC posts in part of North Northamptonshire and South Leicestershire. At the time I never disclosed this information even to my closest friends. Now twenty years have passed since the Cold War ended the Internet provides a good medium to disseminate the details of these defunct systems.
