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".
Revealing mistake: When a Viper is launched, it is catapulted forward from a standing start, and the pilot is thrown back forcefully into their seat. But the very first time Apollo's Viper is launched, the background image shows the Viper is already racing forward before Apollo is thrown backward- the actor missed his cue.
Revealing mistake: It appears that just about every Viper that is launched has the exact same dark smudge on the canopy glass (along the forward, sloped edge of the side glass). Apparently the same full-scale mockup was used for most of these scenes.
Revealing mistake: During the sequence where Starbuck is attempting to land his damaged Viper on the Galactica flight deck, Athena begins running a diagnostic scan on her computer. In the first insert shot of her computer screen, near the top right hand side of the shot, the words "MADE IN USA" are legible in the diagram. These survivors of the "12 Colonies" are searching for a mythical 13th colony known as "Earth" that they've never been to, so having American software is quite out of place.
