Re: Scaling the Excelsior Filming Model
I'd argue that Spacedock Earth is exclusively for embarkation and disembarkation - the equivalent of a commercial airport, only in orbit. Perhaps it's even a civilian installation for the most part, with Starfleet just holding a pier or two (at least during the militant 2280s).
Yeah, I like that a lot. It's "Spacedock" rather than "Starbase 1", it has a cantina full of civvies and pirates, and it's got some truly abysmal policemen. Having it as the main space hub for Earth makes a bit more sense of the scale of the thing - they'd have to set aside a good deal of space for cargo and things like passport control and quarantine.
