Part 15: Cell 3 West (649)
One of the more bizarre sight at Pyestock is the open throat of Cell 3 West
the last altitude test cell built on the site. The while plastic opening gives access to the largest
test cell on the site, brimming with engine mounting points, various sensors and other equipment.
The cell is a continuation of Cell 3, picking up the exhauster main from the
Air House, and bringing the air flow above ground, into the steel shed in which
the cell is housed.
