1930's Acoustic Locators

Before there was radar, the only ways to detect incoming aeroplanes was to look and listen. In Britain this took on greater importance in the late 1930's as war seemed likely. These acoustic locators were probably kept secret at the time, then ignored and forgotten after the discovery of radar. The massive cement structures are still there, and presumably still work.
