Factual error: Tarrant fails Astronomy 101 here, just as Travis did in the first season. He tells the clerk, "I'm surprised you've heard of it (the FSA), if you're from another galaxy." The Tharn and his minions were not extragalactic; they were from other planets in our galaxy. (00:35:10)
Revealing mistake: Liberator's auto-repair circuits have mysteriously stopped functioning. The molding on the top center flight deck console is hanging loose, a glitch that remains for several episodes. (00:23:50)
Ultraworld - S3-E10
Plot hole: When Ultraworld first shows up on the Liberator's screens, all scans show it isn't there. Avon explains it can't be detected because it is an artificial planet using alien technology which blocks all electromagnetic radiation from escaping. But the crew are looking at it on their screen - the ordinary visible light we use to see things is part of the electromagnetic spectrum too.
Continuity mistake: When Jarvik and Dayna teleport up at the end, her bracelet disappears as they materialize in the teleport bay, but is back when they reach the flight deck a few seconds later. (00:44:30)
Sarcophagus - S3-E9
Revealing mistake: When Tarrant, trying to call Dayna, falls against the flight deck console, the whole thing tilts visibly. (00:38:45)
Continuity mistake: Avon refers to Tarrant hitting him "over the back of the head." But Tarrant didn't. He struck Avon from the front, on the forehead, and not from behind. (00:05:30 - 00:40:45)
Continuity mistake: The Liberator gun Avon uses to kill two of the three troopers on the flight deck disappears entirely between shots after he's hit by the third trooper's return fire. (00:33:50)
Ultraworld - S3-E10
Factual error: The Ultra may be expert collectors of knowledge, but they have their facts wrong about Avon, who tried to steal 5 million credits from the Federation banking system. The Ultra think it was 500 million. (00:10:05)
Factual error: Liberator's medical treatments are certainly weird. Vila dresses Avon's wounded arm with padding that's put on over top of his clothing. (00:37:20)
Visible crew/equipment: When Avon and Tarrant are consulting Orac about cloning, an equipment shadow crosses Avon's chest. (00:19:20)
Revealing mistake: When Liberator moves into view on Servalan's screen and stops, a bad special effects matte causes the stars behind the ship to keep on sliding to the right. (00:21:35)
Other mistake: As the Auron pilot's ship is being brought aboard, a bad scratch on the special effects film briefly creates a large black gash on the hull of Servalan's whale-shaped spaceship. (00:03:05)
Visible crew/equipment: As Servalan begins explaining her nefarious plan to the captured Avon, an equipment shadow slides across the blue diamond-shaped pane just behind her. (00:40:30)
Factual error: Cally's bracelet falls off while she's being dragged to the platform by the troopers, but she somehow manages to teleport down to the planet with them anyway. And the lost bracelet later miraculously appears on her wrist in time to bring her back up again. (00:34:45)
City at the Edge of the World - S3-E6
Continuity mistake: The probe Vila uses to collapse the door's forcefield vanishes when the forcefield actually collapses. (00:24:05)
Continuity mistake: In his scuffle with Servalan's trooper, Vila's teleport bracelet falls off and rolls away. We're even shown a close-up of it as it comes to rest near the dropped gun. Yet in the very next shot, as the fight continues, the bracelet is back on Vila's wrist. (00:37:20)
Continuity mistake: As the ship falls into the black hole, Cally loses consciousness with her right hand beneath her head. A few shots later, her position reverses and she's lying with her left hand under her head. (00:10:40 - 00:11:35)
Factual error: Tarrant is some pilot. He miraculously gets the LEM into orbit without any rocket boosters or propulsion system of any kind - and with its landing gear still attached. (00:46:50)
Sarcophagus - S3-E9
Revealing mistake: Peter Tuddenham was the talented voice behind most of the Blake's 7 computers - Zen, Orac & Slave in particular. In "Sarcophagus," Zen is under attack from the telepathic alien mind brought aboard, and its voice changes pitch, rate and timbre as it struggles to ward off the attack. During many of these moments Zen sounds exactly like Orac or Slave, since normally those computers' voices are Peter with the same type of pitch/rate tricks anyway.
