Continuity mistake: The XK72 space station has a distinctive shape, with a large ringed aft section that's to the right of the screen every time we see it. Liberator is moving past that section at the end, passing on the right. But in the next shot, the ship is abruptly heading away from the station, which is still in the same position, and flying left, in the opposite direction. (00:47:15)
Continuity mistake: Liberator's orientation relative to the space station changes. As viewed from inside the administrator's office, the ship is "parked" parallel, with its port side against the station. But in the subsequent exterior view, Liberator suddenly has its bow pointed directly at the station instead.
