I am the purple kerbal and an eccentric scientist. I’m particular with crafts that use OPT Spaceplane Parts, Mk2 Expansion, Near Future Technologies, Procedural Parts + Wings, and spaceplanes that can steadily operate at Mach 6+ in Kerbin atmosphere, or operate in style in Duna atmosphere. A few alien-looking ships will turn up as well. Someone in my crew may be leaking those, then.
