The Buildings

The Plenum Chamber to the immediate east was a huge, dark space and not easily explored without torches. A metal walkway led into the Plenum Chamber and stopped in mid-air – this would've given access to the supersonic blowing nozzle, which could be adjusted to change the airstream entering the cell. Unfortunately the blowing nozzle had been removed, leaving behind this empty space.
