The incredibly intrusive RAF Menwith Hill

The global ECHELON spy network, much employed by US and British governments, is the reason why Royal Air Force station Menwith Hill exists. Containing extensive satellite tracking ground systems, this communications intercept, and missile warning site, has been called the largest electronic monitoring station on earth. Ground station for satellites, of the US National Reconnaissance Office, serving the US National Security Agency, the station is famous for having antennae contained in highly distinctive white radomes. Believed by some to be part of the ECHELON system, reportedly created for the purpose of monitoring military and diplomatic communications, from Soviet Union and Eastern Bloc allies, during the Cold War, and these days i believed to search also for terrorist plots, drug dealing information, as well as political and diplomatic intelligence. Also believed to be involved filtering all telephone and radio communications in the western world, though not proven, this is an incredibly secretive and well guarded place that the public can never get into.
