Check out the Statue of Liberty at 4:42. I’d heard of quite a few of these ships, space stations etc., but by no means all. Towards the end they’re just ridiculously huge.
There is a whole series of those–aircraft, ground vehicles, buildings, etc.
Nifty.
I feel like the Star Citizen ships are not even fictional.
I have to quibble with calling the Dyson Sphere and some of the others starships when they’re not ships at all.
Also, they whimped out by not going all the way to Tengen Toppa Gurren Lagann
OK, they had one of the Alliance ships from Firefly, but not Serenity herself? And where was Moya? Three Star Citizen ships, but only one from Starcraft? And nothing at all from Schlock Mercenary-- Credomar, Oisri, the Can Full of Sky, the Forge of Worlds, the Pa’anuri attack ships, the All-Star, and a bu’uthandi could have nicely filled in some of the gaps at the high end.
I was looking for an X-wing and a whimsically-named ship from the Culture, too.
I was looking for Voyager.
Why did they leave out Luna? 
They should have shown Klaatu’s ship, too!
And Jupiter II.
Dark Star!
The copyright date says 2020, but I swear I saw this earlier. Does anyone know if this is a new version or something?
Ever wonder what would have happened if Patricia Neal had been so scared she couldn’t remember “Klaatu barada nikto?” 
An Earth-shattering kaboom?
From the YouTube page: “[T]his new version updates the first comparison of the channel of 2015.”
They should have a disclaimer: “Some ships are more fictional than others.”
Am I right that most of the obvious omissions are because no dimensions were ever specified?
We were probably obstructing their view of Venus!
I watched this the other day, and was unfamiliar with some of the sources of the ships, particularly the ones from video games.
Or because there’s no visual reference for what the ships look like: That’s probably the cause for most of the literary omissions. But we could still have gotten all six General Products hulls (hint: They’re spherical), and the ships from the Honor Harrington series have official illustrations with dimensions.
And there are a number of ships that might not have officially-published dimensions, but which are easy enough to estimate from comparisons with people or other objects of known size.
