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.
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 Cylon ship rams the landing bay and explodes, the many quick-cut fiery destruction shots are lifted from a classic World War II film (possibly "The Guns of Navarone"). Note the stone walls (and the tanker truck just left of center in the second such shot).
Continuity mistake: When Galactica closes the shield for the bridge this time, it is a two-piece design as seen on Pegasus in the previous episode (one piece rises halfway up to meet the second that lowers halfway- like eyelids closing). But before this episode, Galactica's shield was a one piece version lowered from top to bottom to close. There is nowhere for the ship to have gone and had a refit- it simply appears in this episode.
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.
