The New Guy - S3-E3
Visible crew/equipment: After Penny asks everyone on the ship to double-check that everything is tied down, when Will tells Robot that he thinks he found something to help them later, there's a yellow T-mark taped to the floor which is visible at the bottom of the screen. (00:31:20)
Continuity mistake: At about the 30-minute mark, right after Judy and Maureen have a heart about being the perfect daughter, Maureen says "you have to get out of here." When she says this, she slips out of her harness and her shoulders come loose, which is the only reason the two can't leave the ship easily. The next shot we see of Maureen she is back in her harness. (00:30:10)
Answer: The Fortuna didn't have an Alien Engine. The cover story was the Fortuna was to explore Alpha Centauri but it was exploring the rift. The rift is what the Alien Engine creates and explains how the Fortuna was able to travel to a distant planet (what you call "galactic travel").
