The EV simulator at Lunaport was an environmental training simulator used for training cadets and trainees.
Malcolm Reed suffered from gastrointestinal distress during his training at this simulator, a fact which was noted in his medical file. The simulator was well known as "the Vomitorium" among the cadets. (ENT: "The Catwalk")
A Vomitorium is a feature of Roman architecture that has been incorrectly associated with puking.
