Yeah, 30 degrees is a wider margin that real-life physics would allow. A lot of things about the space ship victory condition bother me, and always have. It's like Sid et al. want to have their cake and eat it too. They say they don't want to go into sci-fi techs by projecting anything more specific than "future tech" but then suddenly our current level of technology--approximately where the tech tree ends--gives us the ability to build giant spaceships and cure cancer and now in Civ IV build a space elevator. Oh, well...
Coincidently I used to build my own space elevator in CTP. I'd put a space city right over an equatorial city and then I'd keep building space cities so that they formed a ring right around the equator of the map. It was a silly and pointless thing to do, but I generally was the only one to space in that game--I, um, "prevented" anyone else from creating a presence in orbit--and it just seemed like the thing to do.
