Factual error: Yet again, the writers here confuse galaxies and star systems. Boomer says the intercepted signal may be intergalactic. It's interplanetary or interstellar, but not intergalactic. Huge difference. Neither signals nor spaceships could travel between galaxies in "Battlestar Galactica's" universe.

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.

Factual error: Apollo's monitor picks up the "Tranquility Base here: the Eagle has landed" message, 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. That's impossible when the Eagle had only just landed. The astronauts had to leave the capsule and set up the remote camera first to get that shot.

Continuity: As Galactica attacks a Cylon base star, she is shown banking to port with the base star off her starboard bow. Seconds later, the base star is to port and Galactica is banking to starboard, yet no course change has occured.

Factual error: The Cylon commander orders his centurions to keep scanning the solar system and "continue into the galaxy as long as fuel permits." This was "Galactica's" final misuse of the word "galaxy." They meant, of course, "planetary system," not "galaxy." The terms are not synonymous, and their ships were not capable of crossing between galaxies.

Audio problem: As Adama says, "After that, it's a toe-to-toe slugging match," the shot reverses angles on the word "match," and his lips aren't moving when the word is spoken.
