Looks like I'll be going on the road if I want to get my thrusters fully engineered. The Engineer requires a 5K lightyear distance traveled from home. That's distance away, not just traveled. I only have about 3100 LY distance away and since I'm close to home I have to do the full 5K. My Asp will do close to 50ly jumps so probably about 110 - 120 jumps outwards. Pretty sure I can self-destruct at the end of that and still get credit for all distance. Don't care about exploration credit.
Gonna need a good sound track for this trip.
