Should we post the links here for the manual and installation files or post to O-H first?

Yes, Main Mission did change a bit during the first season. I'd very much prefer do to the season 2 Command CenterIt is completely underground and very different in style regrading computer panels.

yes.Yes, that will work! Same travel tube, right?
Maybe but I'm not sure how to add that.One thing that might be interesting would be to be able to put an Orbiter MFD into the main viewer and into one of the desks. If the interior meshes were VCs, I know that it would work. It would bring some more life into the base.
But in my opinion, I'd go for an updated Century Spacedock and Ultra mission (http://www.space1999.net/catacombs/main/models/w2multramission.html) . Although the science is not quite right, it is based on our solar system and there's some space navigation and maneuvers to do.
