Thor Site in Military Usage
I happened to drive over a Thor site today - still very much in military usage, at (RAF) Driffield. One of the launch pads supports a seriously large off-road training berm, whichI drove up and down in a Landrover Discovery. Other parts of the architecture are still vaguely discernible in the driver training area. For a good history with drawings of Thor sites, see English Heritage's Cold War History book published about 10 years ago.
ps. Sadly the Officers' Mess at Driffield was demolished - only last year. The airfield is used for MOD driver training and part of the admin site is a cadet training facility. A few of the quarters are still occupied by RAF personnel.
