Ahhh! But it is not just an ordinary class 10,000 clean room. Our 
ST Tour Guide made it clear that this was by far the largest 
clean room in its class. Afterall, not only is this thing big enough
to hold the HST (vertically), but it looked like it was big enough
to hold 3 HSTs, not to mention all of the support equipment.
