Deep in the South West of England, in the county of Wiltshire, is a former RAF base called Rudloe manor. At first glance, the building looks like any other quaint English manor house, but, deep beneath the structure lies a vast network of underground tunnels and chambers. Contained within their walls is a closely kept secret.

For years, the RAF’s secret service worked at Rudloe Manor across espionage and counterintelligence operations, but also something else - UFO investigations. The claim was consistently denied by the MOD, but in 2007, during a release of declassified files from the National Archives, it was finally confirmed the site was the centre for UFO investigations in the 1950s.
