Dropships exist in Sci-Fi so that space marines can still listen to Fortunate Son in the future.

The video left out one of the most striking features of the Pelican in HELLDIVERS:  Its flight path on approach is almost totally vertical, performing an extreme braking maneuver at the last second.  It also very quickly increases the angle of its flight after liftoff.  It is absolutely focused on the mentality of "get in, get out, don't die" (the Pelicans are actually more valuable than the Helldivers they're supposedly supporting).

"Foster can't you shake them?"      
"Major, this is a Dropship! It doesn't shake, it drops!"      
Always loved that line in MechAssault 2.

Unlucky Clone Trooper: "Good thing those bugs can't aim."

Genosians: shoot down a LAAT with Clone Troopers falling to their doom

I maintain that nothing beats the mission briefing in a dropship trope!
Doubly so if the scene has a killer sound track!

The Aliens helicopter reference was also evident in the name, “Cheyenne.” US Army helicopters types are generally named after American Indian tribes. Comanche, Apache, Blackhawk, Chinook, Lakota, etc

Every other Fiction Dropship: Troop transport.

Battetech dropship: Mech transport. Crunchies are extra.

Republic Gunship has and will always be my favorite dropship

Love the Battletech dropships. With  the two main types. Going from a single 4 mech lance to an entire company of mech, Infantry and ground support. They are truly awesome.

I mean who doesn't want to see a fleet of troop transports dropping into a hotzone? It's pretty epic.

No battletech mention. I am contacting my lawyers. (My alcoholic brother-in law Albert and my cat Bismarck, to be specific.)

One overlooked aspect in SciFi but commonly found in helicopters is medical evacuation. This might be an unarmed ship intentionally trying to look non-threatening (such as painted white) or a ship with some amount of medical facilities on board. It might move casualties to a planet-side medical center or back up to orbit.

6:10 LAATs were originally designed as mostly atmospheric family of planes, but shortly after outbreak of clone wars they were modified with limited void capacity so they could've taken off from carrier with troops and vehicles while in low orbit, I think it was shown in like first battle of Felucia in Clone Wars series

The Valkyrie Shuttle from Avatar and Halo's Pelican (and according to the lore its been in service for 300+ years)... chef's kiss

i remember playing starcraft and hearing the dropship voicelines and being like, "wait, thats the same line from aliens"

Fun fact about the drop ship from Aliens. The guy who designed its look, was a Thunderbirds fan. And considered this look, his version of Thunderbird 2. He would later design craft for the CGI Captain Scarlet series.

I love what Star Wars squadrons did with its dropships. Where it has the U-wing & TIE Reaper serving as support craft in battle

There is something uniquely awesome about dropships

I grew up on Battletech dropships and still have a preference for the spherical dropships from that setting.

One of my all time favourite video game cutscenes is the opening cutscene to the mission "The Ark" in halo 3. Not only because it's got the shipmaster dropping the absolute baller of a line "then it is an even fight", but because of the scene with you, johnson, and the ODSTs dropping on to the surface of the Ark in Pelicans from Forward Unto Dawn, through the middle of a full blown space battle.

Then the opening cutscene of the next mission is the pelicans and phantoms making the run on the towers, again showing off how sick gunships are.
