Revealing mistake: The uppermost of the flight consoles of Liberator isn't fixed down in this episode, and wobbles almost every time it is touched, and not just small wobbles. Watch for the 10 seconds or so after Jenna says "Eventually I might just be able to get her to start and stop", and you'll wonder how she didn't knock the entire prop off whatever it's sitting on and onto the floor.
Continuity mistake: At the end of "The Way Back," Blake, strapped in his prison ship seat, looks over his shoulder at the window behind him as the ship leaves Earth. This same scene is recapped at the beginning of "Spacefall," only now Blake is sitting one seat to the left of the window instead of directly in front of it. (00:49:00)
