This is my first time posting here for a problem I've been having with KSP, so excuse me for lack of conciseness. I have developed a craft which uses twin ram-jets launched from the VAB, to deposit a satellite into orbit. To save money. To save DV on polar/reverse orbits.Because rockets are wasteful. , etc. The problem I'm having is that, despite the existence of somewhat unreliable autopilot mechanisms which I don't fully know how to use it is still very dangerous to launch this craft to APO, burn to orbit, and return to fly the launch vehicle back down to solid land. Manned craft on a re-entry trajectory randomly get killed. This happens when I'm doing an initial orbital insertion burn flying a probe. After the launch vehicle detaches. Usually within two minutes. The re-entering manned vehicle is still well above 50k, but it's either not there in map view, not there in center, dead or bugged stuck still. So I have three questions, all of which can be answered by someone more experienced with these types of problems: How can I reliably instruct a probe to execute a maneuver and return to control my launch vehicle back down to the groundd In what ways is it possible to control two vehicles at once autonomously per program (need to wait for unity upgrade/engine problems?) How can I tell the engine not to kill craft on a re-entry trajectory if they contain Kerbals? Here's a craft file link ay And an image of the problem before I burn the probe for insert and lose the craft
