What if you could put launch/landing pads at your save locations. Maybe you would choose through a catolouge that have many different looks, like maybe one looks like a remote airport or an arctic base like in SimplePlanes. There would be biome variants for some of the simpler ones (Acrctic, plains, alpine, cylero, luna, etc.) and ones meant for specific places, like maybe some domes for ones for Cylero. I'd think they would automatically try to be level, so if they are placed on a steep hill, the pad would not be sideways. I'd assume they would do the same thing for vehicles launched from them.
This will probably be in the planet builder
