Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
This month a couple of questions have used the shuttle tag. Both were clearly asking about STS which is covered by [space-shuttle]. I've edited both questions and replaced the tag; can [shuttle] be deleted or merged or something?
I went ahead and made shuttle a synonym of space-shuttle to prevent this from popping up again.
