No introductions are needed for this place. It's where the MOD and others tested aerospace engines and the likes from the 1950s up until closure in the 1990s. Today the massive buildings stand empty apart from the odd explorer, security guard or pigeon.
I don't pretend to know all the different structures, but it's a truly masive place to attempt solo and being inside some of the massive buildings was awesome
The place is very pipey though and you will spend your time clambering in, over and under the fucking things for hours.
