Plot hole: When the Liberator returns to the planet, Travis remarks that their orbit is too far away to use their matter transmitter. Since Travis had only found out that they even HAD a matter transmitter (which the Federation hasn't managed to develop yet) when he spoke to a technician just before that, how would he know what the range was? (00:43:50)
Plot hole: When he first shows the burned ison-crystal to Cally, Avon says that its loss will blind the Ortega's forward vision. Later, he assigns it a completely different function, saying it controls the hyperdrive instead. If this one little crystal is that vital to the ship's systems, why aren't these guys carrying a spare? (00:15:05 - 00:19:00)
Plot hole: Kendall stresses that only he can open the safe containing the valuable neutrotope. Yet later, he casually asks a crew member to retrieve it, with no mention of the safe's combination, making it a cinch for the villain to steal the goods and hand over an empty box. Naturally, no one bothers to look inside before Blake races off with the container. (00:16:30 - 00:21:05)
Plot hole: Avon delivers his summation of the crimes and the murderer's identity to the Ortega's crew - with his back turned to the guilty party the entire time. This gives the killer ample time to pull a gun on them. But it's also egregiously out of character for Avon, whose suspicious nature bordered on paranoia and would never have allowed him to be so careless. (00:42:25)
Plot hole: During the entire standoff between Blake & Travis, there is a Federation guard with his hands on his head. Yet when the scene first begins, no-one else is and Blake is not holding a weapon on anyone. Neither has he revealed his play with the virus at this point. After he has done so and left, the same guard still has his hands up. Finally, after Travis has secured the virus, the guard STILL has his hands up.
Plot hole: When Blake teleports to XK72 to meet Professor Kane, he takes 2 teleport bracelets so that Kane can return to Liberator with him. When Avon goes over to retrieve the medical assistant, he neglects to take an extra bracelet. The assistant beams over with one anyway, and Avon somehow still has a bracelet to return with later. (00:34:05 - 00:41:30)
Plot hole: When the newly-acquired Orac is first set up on the flight deck, Blake comments that "the other end's connected." Connected to what? Orac didn't require plugging in, other than putting his activator key in place, and that was never connected to anything else. (00:46:45)
Plot hole: The IMIPAK weapon marks its victims and then kills them with a secondary device. But it's inconsistently selective. When Servalan kills the guard with it, Blake and co., marked and standing nearby, are unharmed. But Rashel later warns Travis not to push the button because he and Servalan are marked and would die too. (That the weapon's range is "adjustable" is nowhere mentioned or implied. Servalan doesn't change a thing before she fires it). (00:43:55 - 00:46:30)
Plot hole: Avon drills the last hole through the bomb's tubing and then, with the drill still in place, has to hunt down the dropped rod needed to block the plunger. Tense drama ensues while it's found and inserted, though simply leaving the drill bit in there would have worked just as well. (00:44:55)
Plot hole: Travis, dressed up as the supposedly disabled dissident Shivan, fools Blake and the rebellion leaders far too easily. His head bandages completely cover his mouth (how did he eat?) and his glued-on glass eye is so obviously fake it's laughable. If we noticed, why didn't they? (00:21:05)
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.
Plot hole: If the "Enzyme Activity" adhered to the hull of the Liberator, how did it enter the ship without causing a hull breach and immediate loss of pressure ? Also, how did Servalan not suspect anything when she boarded, missed Orace and ordered Maximum Power surrounded by green mould?
Headhunter - S4-E6
Plot hole: The 6 second countdown lasts much longer than 6 seconds.
Plot hole: Servalan & Egrorian discover their Orac is a fake when it continues to light up and make noises after the key has been removed. But this makes no sense; the key functions as it should during the demonstration. Even if it's to do with no longer being connected to the real Orac, with the shuttle getting further away it shouldn't function at all.
Plot hole: The drama on the crashing shuttle comes from the idea that a speck of Neutron material is super-heavy. Yet in the laboratory, Egrorian states that 8 Neutrons make up the core of the Tachyon Funnel. This would make it so heavy it would probably sink through the entire planet, yet Pinder, Vila & Avon wheel it about like the aluminium prop it is. And if the Neutrons are held in some sort of anti-gravity field, that would require an enormous amount of power, but Pinder uplugs it at Avon's request.
Suggested correction: Neutrons and Neutron material do weigh differently. 8 neutrons would weigh 8 atomic mass units - immeasurably small. Neutron Material on the other hand is comprised upon trillions upon trillions of neutrons compressed by gravity into a very small volume (and is the theory behind black hole formation). A microscopic fragment of Neutron Material would indeed have a very very large mass, but too massive even for Avon to move. That and the fact that Neutron Material comes from a Neutron Star raises the question of how it was extracted, cooled and moulded into a lump of perspex.
Plot hole: When the warlords lift their glasses in a toast, the same mysterious blue electrical arcs, which later appear and kill everyone in the freight bay, spark and sizzle around their hands. But for some strange reason, no one seems to find this at all peculiar. (00:11:15)
Plot hole: Ordered to kill him, the Federation squadron stakes Avon down - on a sand dune. Naturally, he has no trouble pulling loose and clobbering them all. This is hardly just a "character choice": it's a plot hole the size of Tuskeegee. A trained military unit (which they were) would never be so stupid. They could simply have shot him with no difficulty whatsoever. (00:33:30)
