How do I destroy or pull my cargo shuttles out of space?

I have several hundred cargo shuttles parked on White Giant. They're in space because I didn't realize that when an enterprise or country of mine builds a space port, the game puts all cargo shuttles in inventory into service in space. Now White Giant is polluted with around 400 to 500 of my cargo shuttles.

How do I remove my cargo shuttles from space?

You don't really have to worry about where they are currently located/stored. As soon as you offer a task for them, they should head there and be just fine. They won't decay or anything just sitting there.

They do need SC maintenance, which they can pick up from a space center as they complete tasks, to get the full allotment of missions they are allowed.

No, you missed my point. I don't want them there in the first place. They are worthless to me and an eye sore when I look in the outer space window. Is there a way to destroy them or otherwise remove them from space without having my shuttles perform a cumulative 1 million or so missions? I'm guessing no, but I just want to be sure.

Yes, you sell them.

I guess that is an answer to my question. I knew you could do that already. I was really looking for a way that didn't require the participation of another person. Something like a button that would do it immediately. I guess that doesn't exist. It's fine. The game is old, so I was half-expecting there to not be an easy or quick way to remove shuttles from space. Thanks anyway.
