Plot hole: When Starbuck attempts to liberate Apollo, he captures two guards, saying "Now drop them or I'll incinerate you". They comply and he leads them to a room where Apollo's weapons and equipment are being analyzed. The analyst holds a radio on which we hear Starbuck say "Drop it or I'll incinerate you". First, Starbuck isn't transmitting. Second, he already has the guards disarmed and in custody. Third, the words are not the same as spoken earlier. Fourth, there's no reason such a transmission would have been delayed when sent radio-to-radio. (00:30:35)
Plot hole: The President and the General argue on a podium in front of a large gathering of citizens that are seated all around. When the General is told that their enemies have launched an all-out missile attack that will trigger their own automated response, wiping out both sides in the next six minutes, the audience is completely motionless and doesn't appear to react at all. They take the news that they are all going to die remarkably well. (00:40:25)
Continuity mistake: When Boomer tells Starbuck to check his scanner, it shows three Cylon ships approaching. In the next shot, four Cylon ships attack, not three. (00:03:30)
The Lost Planet of the Gods (1) - S1-E4
Continuity mistake: While on patrol, Apollo enters a void in space, where no stars or other navigational fixes are visible. But in at least one shot, his ship is shown from the left side with stars in the background. It's the shot immediately after Adama says, "That's odd." (00:12:00)
Deliberate mistake: When the Vipers make visual contact with the attacking Cylons, an exterior shot shows a large group of Cylon fighters from the front/right as they drop into view and move left to right. The rearmost ship on the left is a gold color while the rest are the usual gray. This odd effect is also seen in the first episode's first battle as well as during the last episode's last battle- an odd coincidence. The original concept for the show was to have these gold ships be the squandron leader, but showing it every week would be too expensive, so that idea was dumped and the one shot with it got used a few times without explanation. (00:05:40)
Factual error: The Cylon commander orders his centurions to "continue into the galaxy." This is roughly tantamount to the GPS in your car instructing you to "continue to the nearest planet." It makes no sense, as they're not entering any other galaxy (nor could they). Yet again, the writer obviously confused his terminologies, and should have written "system," not "galaxy." Speculating that he meant this galaxy is just silly; it's clearly not what was intended. (00:06:45)
The Living Legend (2) - S1-E13
Revealing mistake: When Pegasus goes after Baltar's base star, Pegasus takes damage to her starboard landing bay. The shot is reversed and a reuse of the same shot from the previous episode when Galactica took identical damage to her port bay. (00:32:30)
Plot hole: At about 35 minutes into the show, the fuel gauge of the shuttle shows 50 units of fuel remain. Five minutes of real time (and far longer in "story time") after, Starbuck begins counting down the fuel level, starting at 25 and dropping by 5 every 2 seconds. At that rate, the 50 original units should have run out within 20 seconds, and shouldn't have lasted over 5 minutes. 'Real world' use of fuel in space doesn't apply, as the canon of this show suggests fuel use is a constant to maintain motion, even in a straight line. (00:35:05 - 00:40:40)
Saga of a Star World (1) - S1-E1
Continuity mistake: In the beginning, when the President says "Noble delegates, you're anxious to go back to your ships.", you can see a servant serving a person across the table. When the shot cuts, the servant is serving another person two seats away. (00:02:55)
Continuity mistake: When Starbuck and Apollo discuss going to see Aurora, the wide side shot shows Starbuck's hair hangs down to the corner of his right eye. But shots showing Starbuck from the front show his hair at least an inch above his eye. (00:12:50)
Revealing mistake: When Starbuck veers off the shot of his thumb and the flight stick is reversed. The "IM" button is on the left and the red "FIRE" button is on the right, opposite from where they normally are. Sharp eyes can even see the word "TURBO" is reversed before Starbuck's thumb covers it. (00:03:18)
Saga of a Star World (2) - S1-E2
Continuity mistake: As Starbuck and Boomer listen to the Council, Boomer's pose alternates from profile to fully facing the council.
Saga of a Star World (1) - S1-E1
Continuity mistake: As Apollo spots the Cylon warships, the lights around the face area go from lit to unlit between cuts.
Revealing mistake: One of the fire crew presses several controls on a panel operating the ship's pumping mechanism. When his gloved hand is shown pressing the first button, the supposedly metal panel flexes and buckles slightly. (00:23:50)
Saga of a Star World (2) - S1-E2
Character mistake: When Starbuck and Apollo cross-wire the lift to reach the lower levels, they forget to undo their handiwork. Convenient to the plot, this oversight allows Boxey to wander into the Ovions' stronghold and require rescuing.
Saga of a Star World (1) - S1-E1
Other mistake: Assuming the Colonial fighters are pretty much identical, Apollo's control stick is marked with usual controls, whereas Zac's stick is marked completely differently, but performs exactly the same.
