Big cleanup needed 
Obviously, this article needs a bit of work.  As I see it, we need two things: sections within the list, and inclusion criteria.

On sectioning, I believe that we would do well initially in making two sections: Proposed systems, and systems that actually made it to production.

On inclusion criteria, I recommend that we limit it to launch systems that have articles.  Some proposed launch systems simply aren't notable.  So they don't get included here.

So there you go, I suppose.   (Talk)
