Factual error: Travis fails Astronomy 101 with the line, "Blake - the other patrols have pushed him into this galaxy." That should be star system, not galaxy. B7's ships weren't capable of intergalactic travel. Not just a character mistake, either. Travis is a trained Space Commander, and should definitely know the very big difference between a solar system and a galaxy, even if the scriptwriters - and people who keep miscorrecting this error - do not.
