Starport traffic

The recent discussion of the *large* amount of takeoffs and landings on the
larger worlds (someone mentioned one every 1.4 seconds or so on Trin) has forced
me to give up on the idea of "one world, one starport."

I think a much more reasonable assumption is that the starport code only
represents the best available facilities on a world.  Most of the interstellar
traffic is going to be handled by existing airport facilities.  After all, you
have everything you need - proximity to large metropolitan areas, pre-existing
facilities for transferring cargo to/from rail or trucks, experience with
dealing with large amounts of air traffic, hangar space, etc etc.

I'm not familiar enough with air travel to be sure, but aren't there 75+
international airports here on Terra?  That would make for roughly one per
couple of minutes, less if you consider that your average scout or free trader
doesn't really need much more than a wide space for a landing facility.  One
PC in a campaign I ran about 10 years ago used to land his ship right outside
of the factory he was buying the weapons he was smuggling (He used to land
inside the fence until an unfortunate mishap involving a lousy pilot and a
tractor trailer).

Sorry I forgot who posted about Trin, but I deleted that message before I
realized had something to contribute on the subject.
