Unclear which kind of infrastructure, aeroway:uav=launchpad ? Should not only be a node, but an area osm.wiki/Key%3Aaeroway%3Auav

2008 discussion abandoned osm.wiki/Proposal:Model_Aerodrome, new namespace: osm.wiki/Key:aeroway#Models

Is there anything launched ? osm.org/node/12999689983

otherwise, I'd recommend tower:type=rocket_engine_test + https://taginfo.openstreetmap.org/tags/industrial=rocket_engine_test for the pad

An "anchor" for what ?

I doubt there's anything launched here osm.org/way/989246921/history

temporary ? osm.org/way/827790088/history

The website looks as if it's paragliding osm.wiki/Tag%3Asport%3Dparagliding

osm.org/relation/7682394

What happens here ? Takeoff / landing ? osm.wiki/Tag:sport%3Dhanggliding

Could someone please verify whether this belongs to Andoya Spaceport ? osm.org/way/1372369263/history

Unclear why there's one "relation" which could be a closed line osm.org/way/834314800 and then a second identical one with a "hole" for "PNMCC" osm.org/way/757096806
