Hi all, I recently tried making a plane with a bunch of rover/probes (Provers?) in the back, to drop at certain locations, parachute down, then activated later to do the contracts for science on kerbin. I thought I had made them too heavy, or not included enough parachutes. But as I've read, space plane "Debris" is destroyed after the main craft is a set distance away. Is there a mod that removes this, and possibly makes terminating debris from the tracker easier?
