Royal Observer Corps in Bromley.
Although Britain had a very useful location system using radio waves in place by the beginning of the Second World War, it had a big problem - it only looked out to sea! Over the bulk of the country, the main detection devices were human ears and eyes. Lots of people were watching the skies, but somehow that information had to be got to where it could be best used. In the years just before the war, an imaginative and technically advanced system was created and set up to do just that.
This is the story of the Bromley Centre during the War.
In course of preparation.
