I second the rotatable mechanism. This not only addresses the collision potential during deployment but also opens up new mission potential. One can use it to - facilitate station building without a separate tractor/tug to position the new module. The shuttle can do it all. - carry a standalone docking port for those hard to reach station or vehicle ports. Useful if you don't want a permanent port just for the shuttle - recover Kerbin-orbiting satellites, and, - capture planetary or munar probes to return their science payloads to Kerbin for full science credit. (This is my favorite in this list) One could build a rotating "mount" with other mods - but it wouldn't have the feel of one unique to KSO. The unmanned, wingless version has potential but I favor just the unmanned version. Keeping the wings allows it to fulfill the missions listed above. Thoughts?
