"it would be pitch dark inside a labarynth of sloped decks and corridors"...you paint a vivid and terrifying picture with these wordsI would conclude that engineers and supervisory personnel likely remained inside, even if they had told staff to make a run for it. Once the power shorted out or the generators failed, it would be pitch dark inside a labarynth of sloped decks and corridors. Trying climb out and find stairwells and ladders would be managed only by touch and familiarity with the spacial arrangements. Using a robot to explore the engineering cavities of the ship would give evidence in the form of boots and gloves. Pretty horrible way to greet death.
