Saga of a Star World (1) - S1-E1
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.
