Shortly after the launch of a satellite from a space shuttle, the satellite collides with an UFO in front of the crew's eyes. Because of an upcoming election, some politicians try to hide the crashed UFO inside Hangar 18.
- Hangar 18 is a 1980 film that was released to capitalize on the UFO interest of the era. Although it flopped rather badly (reportedly earning a gross of only $6 million), it tantalized those who saw government cover-ups of UFOs (such as the Roswell incident) as dirty laundry needing to be aired. 
- Heavy-metal band Megadeth performed a song named "Hangar 18" based on this movie.
Prologue: In the shortest host segment ever, Joel introduces the film, and then it's movie sign!
Segment One: A meteor shower is about to strike the Satellite of Love! Joel explains the tragic consequences if the hull is punctured and the ship loses its oxygen: "No more Kibbles n' Bots, and no mid-morning pleasure stimulations!" Crow tells him to lighten up. (This segment appears on the MST3K Scrapbook tape.)
Segment Two: Joel purges Crow's memory, dumping all non-essential rememberences. "Every Punky Brewster episode? Dump! The Lyle Waggoner Penile Implant Show? Dump!"
Segment Three: Joel taps into Crow's brain, and shows him his first memory--the moment when he was first turned on. In the bit, Joel explains that "CROW" is actually an acronym, which stands for "Cybernetic Remotely-Operated Woman." Crow, alarmed to discover that he's really female, begins to panic ("Thirtysomething is on! I need some chocolate!") until Joel reveals it's all a joke. (This skit appears on the MST3K Scrapbook tape.)
- The opening host segment/prologue is the shortest host segment in the history of the show.
- The scenario of facing a meteor shower and it's consequences would almost have been revisited in Mst3K the movie (but due to the extreme meddling it received, has been cut).
- Joel hits his head on something in the prologue.
- "He was in 'Teen Wolf', wasn't he?"
Teen Wolf was a 1985 movie starring Michael J. Fox.
- "He's drinking Helsinki Formula!"
Helsinki Formula was a baldness remedy endorsed by Robert Vaughn in a series of infomercials.
- "I thought you meant H.R. Giger."
Artist H.R. Giger is best known for designing the title creatures from the Alien film series.
- "I said 'lunch', not 'launch'!"
