They were ushered into a control room separated from the building’s cargo bay by a wall of windows that seemed inordinately thick. In spite of that, they were each given full-face respirators and taught how to put them on when and if a certain alarm were to sound. The previous conversation about sulfuric acid in the lungs had left little to the imagination and so all of them paid due attention. In the meantime, on the other side of the glass, workers in white bunny suits and respirators were working on a system that, to the eyes of a layperson, consisted entirely of plumbing. At the end closest to the open bay door, basically outside the building, was the object that seemed to be the point of it all, tended to by the bunny-suited priesthood on the far side of the glass. But even this was just plumbing. It was a pipe on a stand, aimed out at the world.
