I am not surprised at the paucity of explorers; I was stationed there for Exercise pinnacle in (I think) September 1951. When I arrived, I was met with a small building, that seemed to compose an outer office and a lift shaft. I believe the Ops room was about 120 feet underground. No smoking; fire buckets packed with cigarette ends. On a rare trip above ground discovered two large mushroom air shafts which may have also been emergency exits but I believe there was also a connection with Brown's Quarry. Think that was RN. Not comfortable but a real privilege to have spent a fortnight with a busy control room; huge table and WRAFs doing the plotting with controllers on the mezzanines. I was a National Service meteorologist. I think I would prefer to have my memories rather than crawl around a bare, deserted complex.
A small stone quarry to the north of tunnel quarry in Corsham which was converted and used as the underground headquarters of No. 10 Group Fighter Command and as a ROTOR training station, the site is now abandonned.
