I didn't mean access restrictions, but the structure. "spaceport" should be the enclosure of the whole complex. In case there are two different areas WITHIN the spaceport with different access keys, it's still the same structure ? Here's an example where every single unit of the spaceport was also marked as a such : https://wiki.openstreetmap.org/wiki/Tag:aeroway%3Dspaceport#Common_tagging_mistakes
And it looks similar at cape canaveral : https://overpass-turbo.eu/s/1hlJ
