The Titan III transtage doesn't work. It has the correct fuel mixture, but the engine does not operate at all. I know it works in BDB normally, and as far as I can tell the only thing which is modifying it is Skyhawk Science System. The transtage is important for several major rockets, including the launch vehicle for DynaSoar, and it is not reasonably practical to simply substitute other parts for it.
