The droid here, G2-9T, is so busy chatting with us that he's not paying much attention to the intergalactic luggage moving through the security x-ray scanner behind him, even though that's ostensibly his job. Thus, we see lots of weapons and smuggled things inside. A great many are nods to Star Wars, but others are Disney specific.
There are 71 bags scanned (plus a further one or two that don't get scanned since the droid basically malfunctions for a few seconds as part of the show). Why 71? I'm guessing this is a tribute to 1971, when Walt Disney World first opened. I present all 71 to you here, in order as they appear at the ride (it repeats the cycle after it's over):
Battle droids. "You can call me Roger, if you want to." A Bambi reference!
Ewok playing drums on Stormtrooper armor.
Droid parts.
Major Domo from Captain EO.
A computer (which G2-9T blows up)
Mouse gloves.
That is NOT a toy. "To Tatooine... and beyond!"
Droid parts.
Captain Rex, our original Star Tours pilot.
Lando Calirissian, G2-9T says.
Incredibles suit.
Podracing gear.
C3PO's legs.
C3PO (who wakes up and curses at G2-9T... who then uses C3PO's own line "how rude" as a reply)
Space helmets. The oxygen tanks are labeled with the old logo for Space Mountain and "DASA" (Disneyland Aeronautical and Space Administration) - both from Disneyland in the 1970s.
G2-9T ignores all that, though. Instead, he sings "Star Tours, nothing but Star Tours" which is an adaptation of the "Star Wars" song created by SNL's Bill Murray.
Wall-E.
Teenager luggage: skateboard, roller blades, flip flops, cap and glasses.
C3PO's torso.
V.I.N.CENT, from the Black Hole movie.
A computer.
Figment. An earlier version of this scan showed Stitch instead. In both cases, the "live animal" was quarantined.
Hiking gear.
"What a cute toy Ewok!" (it moves a moment later)
Sorcerer Mickey hat and broom.
"Someone packed a lot of hair dryers!"
SCUBA gear.
Wall-E's stuff: lights, a VHS tape, a shoe with a plant growing in it.
Fashion alert! Are these your shorts, sir?
Droid smuggled into luggage.
This droid's head pops up, but I can't remember what it is. It looks a bit like Timekeeper's 9-Eye, but not exactly right.
"Someone's going to a costume party!"
G2-9T says: "What is that? Oh I see... IT'S A TRAP!"
Tennis racket, which G2-9T destroys as a threat.
Various weapons, which are allowed to pass.
Dangerous weapons that pass by, while G2-9T assures us he sees everything.
G2-9T's former coworker.
Droid parts.
Chewbacca's crossbow.
Musical instruments.
A lightsaber, which later ignites. Or as G2-9T calls it, a flashlight. "Always good to have in case the power goes out. And YOU THINK ABOUT THAT NEXT TIME" (a quote from Ellen's Energy Adventure).
"Give him a hand!"
Pit droid reading a tablet computer.
Jedi remote for lightsaber training.
Wall-E, again.
Mad Hatter's headgear.
R2-D2 mouse ears.
Helmets, gloves, and disc from TRON.
A dangerous tourist camera, which G2-9T destroys.
Hiking gear (mirror image)
Monsters Inc. teddy bear.
It's a riddle: O-bee-wand-key-N-"o"-B (Obi Wan Kenobi)
Fedora, coiled whip - must be Indiana Jones's luggage.
Captain Rex, again.
Goofy doll.
Cowboy stuff (and a fiddle).
Another stowaway R2 unit.
Stowaway Jawa.
Droid parts.
Chip & Dale.
Madame Leota from the Haunted Mansion.
A dangerous musical "weapon" which G2-9T destroys.
Teenager luggage (mirror image)
TK-421's bag. G2-9T wonders why he's not at his post.
"This job [scanning luggage] beats welding old droids back together."
"Souvenir hats in the shape of Jar Jar Binks - how goofy is that?"
Anyone going to Hoth?
Homages to Adventure Thru Inner Space, the dark ride which preceded the Anaheim Star Tours (and showed a snowflake under a microscope - with us shrunk down to that size as well).
Aladdin's lamp.
Pit droid reclining like Luke, playing with a TIE fighter.
Stowaway droid.
Luke's set of mouse ears. As G2-9T says "This bag must have a twin!"
It's not clear to me if the narration has changed since the ride's re-opening in 2011, or if there are variations the same way that the ride itself has variations, but my visit on 9/8/12 did not line up perfectly with videos from 2011, either in the order of scans, the voiceover used by G2-9T (it was 80 to 90% the same, but not 100%), or the actual contents on the scan.
