The Constitution (USS Enterprise) from Star Trek was only 289 meters? Kind of hard to believe it held a crew of I believe thousands of people. That's with all the amenities of a large mess hall, holodeck, medical ward, and literally hundreds of randomly placed traps and gauntlet like obstacles.
EDIT: Hmm, it seems there were only a bit under 500 people on the original Enterprise. My mistake. Still seems cramped considering a fraction of its size was actually interior living space.
