Finally, a door! And it opened. I was quickly inside with Tom following. Immediately to our left was a huge blast door, inches thick, behind which was a dark cool interior. I dived in with Tom following, firstly ensuring that the door was propped open with a handy chair, just in case there was no-way out. Relaxing now, I rummaged through my rucksack for a torch.

We were in another control room. More dials and controls littered the east side of the room, with the rest of the space taken up by hexagonal tables and chairs. The instrumentation was made from individual plastic squares; someone had punched out "Pyestock" in a crude font on one of them. Another space recognised from the various pictures on various sites. Another space now firmly nailed down and identified.
