Spaceflight is about the process
Spaceships is about the technology
...I was struck by a thought.
Given the similarity in naming of the two tags, which apparently is contributing to some confusion, it might be easier to tell the difference between the two if we rename spaceflight (the process) to space-travel (possibly adding spaceflight back as a synonym) and keep spaceships the same (possibly adding a synonym spacecraft because that is a well established term in the industry).
It would seem to pretty well match the current tag wiki, which says in the excerpt that spaceflight is...
For questions about the process of travelling through space, including in orbit around a planet or moon.
Opinions on this?
