I have a question that pertains to the new comm-sat mechanics that were added to the game recently. I know that unmanned ships need to have a path to the KSC in order for them to be controlled, and that manned spacecraft can control themselves regardless of whether they have line-of-sight to Kerbin or not. But when controlling unmanned spacecraft, will any Kerbal pilot with a connection do? For example, say I had two spacecraft, one remote controlled, and another with a Kerbal crew, and neither of them have a path to the KSC; is it possible to control the unmanned spacecraft using the Kerbal pilots in the manned spacecraft? Or do I have to set up relay satellites in order to establish a connection back home before I can control the unmanned satellite?
