Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)
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)
Revealing mistake: When the Federation troopers blow open the interrogation room door, you can see a brief glimpse, through the smoke, of the thrown sledge hammer that was used to make the door fall in. (00:48:15)
Revealing mistake: When Blake hastily slaps at the oxygen vent control to close it, the knob breaks off, drops to the floor and bounces noisily away. (00:07:25)
Continuity mistake: When Avon is removing the gas canister from the ventilation system, an insert close-up of his hands shows that he's wearing a wedding ring. In the full shots, however, the ring isn't there. (00:09:50)
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)
Other mistake: When Avon and Cally are taking off their gun belts to hand them to Blake, Avon accidentally clips himself in the chin with the protruding barrel of his gun. (00:22:00)
Visible crew/equipment: Just after Avon says that the numbers on the clipboard mean absolutely nothing, the boom shadow moves across the top of the metal safe set into the wall behind him. (00:41:30)
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)
Other mistake: Just after Cally says that the pilot's death was "a misfortune," she stands and her chair scrapes noisily on the floor. The sound apparently startled Paul Darrow, causing the always-unflappable, nerves-of-steel Avon to flinch: the only time in all four seasons that he's ever seen, albeit briefly, to break character.
Factual error: Travis fails Astronomy 101 with the line, "Blake - the other patrols have pushed him into this galaxy." That should be star system, not galaxy. B7's ships weren't capable of intergalactic travel. Not just a character mistake, either. Travis is a trained Space Commander, and should definitely know the very big difference between a solar system and a galaxy, even if the scriptwriters - and people who keep miscorrecting this error - do not. (00:03:10)
Visible crew/equipment: When Vila asks Avon if he ever cared for anyone except himself, an equipment shadow scurries rapidly across the set behind him. (00:37:45)
Visible crew/equipment: When Blake and the landing party are on the flight deck, preparing to go down to the planet, something black intrudes on the left side of the screen during a shot of Avon on the flight couch. (00:08:50)
Revealing mistake: As Jenna leaves the flight deck and heads down the access corridor, a camera is briefly visible just to the right of the hexagonal entryway. (00:09:20)
Visible crew/equipment: Ah, the hazards of shiny metal set walls. When the doctor closes Avalon's cell door, there's a hazy but discernible view of the camera and a moving film crew member. (00:30:30)
Revealing mistake: When the fight begins in the detention block and the trooper runs away from Jenna down the hall, two large blaster holes appear in the wall he runs toward - before the first shots are fired. (00:34:45)
Continuity mistake: During the firefight in the detention corridors, the blaster holes in the metal wall Jenna's firing toward keep changing, sometimes disappearing altogether. One of them is created twice, appearing as the troopers duck out of sight, vanishing and then reappearing in the same spot when Jenna fires again. (00:36:00)
