does it have to be 4.2? or will a newer version work?
An easy way to answer that is are you running Orbiter 2010p1? Ir you are, then the newest version of Shuttle Fleet will suffice. But you will have to PM me for the link. I won't post it.
there has been a few newer versions that add some things. If they are compatible, and I don't see why they wouldn't be, I would recommend using the new stuff. They add some nice things, like UMMU, expanded GPCMFD, some visuals.
David413 explicitly removed the Shuttle Fleet from the community for a reason (search the forums). He is certainly not permitting redistribution without his permission, so O-F staff will not allow links to unapproved download sites.
If you want a link to the Shuttle Fleet, your best bet is to contact the author, or a fellow Orbinaut in private.
