> It is, of course, actually an aircraft, like all satellites, to some degree, at least in the layman's definition of the word.

doesn't the layman definition of "aircraft" require air?

Right. Also, the layman may assume that space is a total vacuum (so absolutely no air), even near the earth.

isn't the air at orbits of most satellites (4x starlink) so thin that it's effectively vacuum?
