Audio problem: When the first reporter asks Saville, "Have you found an answer with Skythrust?", he is voiced by Jeremy Wilkin. When he says "Yeah, captain, make a statement", he now has a completely different voice provided by Paul Maxwell.

Continuity mistake: When Scott is in the cockpit of the Mole, he has two blue tubes in the holsters of his belt. But when he is cutting through the fire doors, the tubes have changed to one blue and one yellow.
