Closest Thing We Got: Brought up, then intentionally subverted, as this time Striker does know exactly what he's doing, but it's the shuttle that's malfunctioning.
Continuity Nod: While talking to Buck Murdock on the radio, Ted says "Roger, Murdock". Roger Murdock was the character in Airplane! played by Kareem Abdul-Jabar. The scene even does a beat so you don't miss it.
In the courtroom scene one of the jive talking passengers from the previous movie appears as a witness, as does the hysterical woman.
McCroskey's Droste Image gag is repeated. With one extra layer added.
Conveniently Coherent Thoughts: Played for laughs. After the Mayflower space shuttle malfunctions, someone in the space traffic control room asks "What do your people think?" The audience is briefly granted the power of Telepathy so we can hear the controllers' thoughts.
Controller #1: They're screwed. Controller #2: They're dead. Johnny: Did I leave the iron on?
Courtroom Antics: Both the prosecution and the defense during Ted Striker's trial.
Flashback: A woman is testifying in court and has flashbacks to when everyone lined up to slap her out of her hysterics in the first movie. This memory sends her into hysterics...
Franchise Zombie: ZAZ has made it quite clear that they had no part or interest in the sequel (in the first movie's DVD commentary, they admit they've never even seen it), thinking that all of the good ideas had been used.
McCroskey: "I want you to tell me everything that's happened up until now." Johnny: "Well, let's see. First the Earth cooled, and then the dinosaurs came. But they got too big and fat, so they all died and they turned into oil. And then the Arabs came and they bought Mercedes-Benzes. And Prince Charles started wearing all of Lady Di's clothes. I couldn't believe it! He took her best summer dress and he put it on and went to town..."
Overcrank: Parodied; when Joe Seluchi hurls the briefcase with the bomb into the air, its brief flight is shown in extreme slow motion, but during the scene one of the passengers, in normal time, checks his watch as if to wonder why everything's suddenly going so slowly.
Ridiculous Future Sequelisation: As Joe Seluchi buys the bomb in the spaceport gift shop, in the background is a poster with a 90 year old man in boxing trunks and gloves with the wording "Rocky XXXVIII".
Rousing Speech: Subverted. McCroskey tries giving one to Striker like in the previous film, only for Ted to point out that he's fine; it's the ship that's screwed up. Later, Buck Murdock tries it, but gets so involved in his own narrative that he's completely oblivious to the fact that Striker has already landed.
"No, why don't you take care of it?"; "No, not a 'bu-', a bomb," and many more.
(Following Ethel Merman in the first film). "He thinks he's Lloyd Bridges..."
Saying Sound Effects Out Loud: The Moon base has automatic doors that make a Star Trek style whooshing sound when they open. However, unlike in Star Trek, they don't open or close on physical proximity, but when the person leans into the door's microphone pickup and makes the same "shh" sound.
Guess what Shatner's character sees through the periscope?
When the shuttle takes off, the song playing is straight from the original Battlestar Galactica theme.
In fact, most (if not all) of the movie's soundtrack is actually the Battlestar Galactica theme. The Dramatic Theme played when we see the Mayflower 1 heading towards the sun is the "dramatic music" from Galactica.
To Jeopardy!: "Art, I'll take Air Shuttle Disasters for $40." "The answer is....the Mayflower!"
Airport officer 1: "We could get McCroskey." Airport officer 2: "I don't know. Ever since Reagan fired the controllers, he's been completely senile." Airport officer 1: "Yeah, but what about McCroskey?"
There's also one against Public Broadcasting: Two women discussing how the shuttle wouldn't have gotten into trouble in the first place if it had been piloted by vegetarian women instead of meat-eating men, while a third translates into sign language.
Terrorists Without a Cause: Joe Seluchi tries to blow up the shuttle so his family can receive his insurance money; it turns out it was an auto insurance policy, not a life insurance policy.
FBI Man: "That's right. This clown is impotent, suicidal, and incredibly stupid."
The suitcase with the bomb has stickers from touristy places like Dresden, Hiroshima, Iwo Jima...
Unintentional Period Piece: Where to start? From the complete lack of security checkpoints to smoking on airplanes to airlines that actually serve meals. Flying sure has changed.
Values Dissonance:invoked Parodied. At the "Ronald Reagan Hospital for the Mentally Insane," the sign reads "We Cure People the Old Fashioned Way". Cut to a bunch of orderlies beating a patient with slapjacks, while telling him "It's for your own good!"
Video Phone: Parodied. Someone on the moonbase turns on a screen and after some static and wavy lines appear is able to get through to Buck Murdock. There's a brief conversation, then Murdock opens the door in front of him to reveal that he was talking to the man through a window.
