Continuity mistake: When Baltar turns to face the two setting suns, we see the lower one at the left has what could be a boat in its reflection on the water. The higher one on the right is over a mountainous area on the horizon. The next shot is of Baltar in close-up, then the next returns to the horizon to show us Baltar's view, which shows just ONE setting sun. The one on the left has vanished though there is room enough for it to have been seen in this shot.
Continuity mistake: When the Warriors are playing cards, Starbuck places his cards on the table near the gold coins, saying "A perfect pyramid. Unless there's a better hand, the pot is mine". His right fingers tap on the table and his cigar is in the ashtray. When the shot cuts, his hand is suddenly up by his mouth, holding the cigar, and the cards and coins have vanished.
Revealing mistake: In the second shot showing the fleet of Battlestars (from the port side and slightly behind), two ghostly images fly in formation with the three Battlestars shown. They are just above the closest ship (where the narrow middle meets the larger rear section). It seems that the shot may have originally contained 5 ships and an attempt was made to 'remove' the most distant two, leaving the "ghosts".
Factual error: Apollo tells Boxey they're leaving their star system and entering "a whole new galaxy." Wrong. Throughout this episode, the writer confuses solar/star systems and galaxies, which are vastly (literally) different things. Even with hundreds-of-times-faster-than-light drives, Galactica's fleet would need thousands of years to cross between galaxies.
Continuity mistake: The Commandant of the Alliance destroyer is told the homing beacon on Paradeen is no longer transmitting. Yet in the next scene on Paradeen, Michael asks Vector if the beacon has been destroyed, as ordered, and Vector replies that he forgot to do it.
Plot hole: Starbuck and Apollo fool the Cylon basestar into believing they're two full viper squadrons. The Cylons haven't yet fully retreated behind Carillon (they order this as we watch), so their scanners should have been able to detect this deception far sooner than they did.
Deliberate mistake: When Apollo lands the Cylon fighter aboard Galactica, the view forward from behind he and Starbuck is a reuse of the same shot from the prior episode when they landed a shuttle aboard Celestra. Note the headphones they wear, then don't wear in the very next shot.
Other mistake: In the second shot showing the fleet of Battlestars (from the port side and slightly behind), the closest ship has an odd reflection which forms a "pillar of light" radiating down from near the rear of the landing bay. It is an effects error, perhaps created while trying to hide the rod that holds the ship up from below.
Factual error: Apollo's monitor picks up the "Tranquility Base here: the Eagle has landed" message of the first moon landing, complete with a full shot of the LEM sitting on the moon's surface - not from the onboard or outboard cameras, but from several yards away. There's absolutely nothing to indicate that this is some edited rebroadcast (that's one stretch of a rationalization). The implication is clearly that it's live. And when the Eagle first landed there were, of course, no cameras on the moon. (Nor is it necessary to insist that the series would have to be set in the Earth-time 1960s for this to be so. A live signal could take many, many years to reach the Galactica.)
Factual error: Starbuck and Apollo fly into a void and are surrounded by total blackness. This misconstrues the meaning of a space void, which is simply a large area without stars. It does not mean that further-distant stars and galaxies would disappear. They'd still be just as visible as before you entered the void. Even if Starbuck and Apollo were able to leave the galaxy and travel hundreds of thousands of light years into a really big void, they'd still be able to see the galaxy they left behind them.
Visible crew/equipment: When Apollo has briefed the female shuttle pilots about the the pressure suits, Serina tells him she loves him. Apollo then calls for Starbuck to come with him, and as Apollo walks to the door, take a look at the right side of the fire extinguisher beside the door and you should be able to see the boom mike shadow move.
Continuity mistake: When a Cylon ship prepares to ram the Galactica's bridge, a Cylon aboard states "1 micron" (a measure of time) until impact, and it takes 14 real seconds to do so. But when another heads for Galactica's landing bay, a Cylon aboard says "5 microns" until impact, and takes only 9 real seconds to do so.
Revealing mistake: After an avalanche, Apollo gets off a guy he has sheltered. Around them, in the fake snow, are several chunks of ice or snow. As Apollo moves forward, note how they move less like snow, and just like the Styrofoam that they actually are.
Continuity mistake: After Cain leaves the planning session for the attack on the Cylon convoy, Apollo walks toward Adama. In the background is a metal wall unit. At the far right side, halfway down are four small compartments with handles that are all properly folded flush. When the shot cuts to a close-up of Tigh, the second compartment's handle is not stowed.
Other mistake: The very first shot of the episode shows the Galactica is coming through a cloud of "asteroid dust". The ship is intermittently obscured by the black dust, yet the stars in the background remain perfectly visible- barely a flicker as the dust passes through the shot.
Plot hole: In order to extinguish an enormous fire aboard the Galactica, multiple explosives are placed on the exterior hull that are then detonated, opening the ship's interior to the vacuum of space and thus suffocating the flames instantly. No explanation is given for how everything is fine immediately after, yet everyone is up and around, breathing just fine. No holes to repair, etc.
Deliberate mistake: When the large formation of Cylons attack, the graphic that Athena is looking at shows the approaching Cylon ships as triangles, as usual. But it also shows two asterisks leading that formation, and the asterisk is the symbol for Vipers. There are NO Vipers leading the Cylons in this sequence. This graphic is a reuse of the one from the big battle at the start of the episode when Apollo and Zac were being pursued by an earlier large formation of Cylons.
Continuity mistake: The show uses made-up terms similar to metric system terminology when remarking about measures of distance and time. Roughly speaking, microns tend to refer to seconds, while centons refer to hours. But here, when Count Iblis enters the communications area and the video screens malfunction, Athena comments that everything was fine "a few centons ago", suggesting hours, when it was only seconds ago that the trouble started.
Visible crew/equipment: Near the end of Part 1, when Lucifer reports to Baltar that they've located the scout vessels, there's a fuzzy reflection on the back wall of some sort of equipment moving upward and to the left. Nothing in the scene itself is moving that way.
Continuity mistake: When Aurora and her companion are picking up the guns from the closet, you can see the closet contains two racks with several guns on them. At first they empty the upper rack of guns. When it cuts they empty the lower rack, but then the guns suddenly have reappeared in the upper rack.
Deliberate mistake: In a wide shot Cassiopeia announces it is time for the children to go to bed, and they react with normal hoots of false shock and whining. Then the shot changes to a close-up and the same moment repeats, with the children again seemingly surprised and dismayed by the announcement.
Continuity mistake: When Baltar sees the Pegasus, it is approaching with her bow toward Baltar's port side. The next exterior shot shows Baltar's ship heading with its bow toward Pegasus' starboard side, as if Baltar's ship reversed, letting Pegasus pass in front, then went forward again and veered sharply right to avoid collision.
Continuity mistake: In "Saga of a Star World", it's established that the Cylons are entirely robotic. Their creators, a reptilian race also known as Cylons, were made extinct by their robots millennia ago. Yet, when Omega reports that life signs have been detected, Apollo asks "Cylons?". Apollo is the character that previously explained their history, so he knows Cylons aren't life forms.
Revealing mistake: When Adama orders the fleet to "Flank speed ahead", the next exterior shows Galactica, seemingly turning to port, but looking at the landing pod shows the image is a reversed shot of the ship turning to starboard, evidenced by the ship's name being backwards.
Continuity mistake: When the Galactica goes to battle stations, Starbuck's card game is broken up. He rises out of his chair in a close-up to try to keep the other players from taking back their money and leaving. In the next wide shot, he's still seated and rises again.
