Factual error: Avon and Vila watch the rocket launch from the surface of the planet. The rest of Liberator's crew also watch it from the flight deck, and somehow their view from orbit is at exactly the same angle from which Avon and Vila are seeing it: a ground-to-air shot. (00:03:15)
Revealing mistake: Due to recycled stock footage from "Space Fall," the Liberator leaving Fosforon at the end of this episode still has the prison ship London attached to its hull. (00:49:25)
