I noticed that someone had confused the words EXPANDABLE and EXPENDABLE and used the wrong tag.
To avoid confusion I added a description for the expandable tag.
However, I'm not sure if the best course of action now is to write a description for the expendable tag, or just delete it. It may actually have value considering the context in which it is used: expendable versus re-usable spacecraft and components.
Just wanted to see if there was a consensus.
