While the base remained active, this area would have been heavily guarded, with high fences and plenty of barbed wire. Quite when the airforce officially pulled out is open to debate. Paul suggests that secret research was going on here right into the 1980s. He talks of bright lights in the sky and loud noises in the night.
Certainly there's an air of X Files/Roswell type conspiracy about the place, that coincides neatly with talk of UFO sightings.
On the other hand, a lot of these old bases were bought by turkey farmers after the war, so the bright lights could simply be for the night-shift workers, and the noise the nervous gobbling of the condemned birds.
