Defcon's KASA program. I have no actual words yet, besides a giant engine and a new matter. Requires my Placeholders. You also may have to delete your swept wings sadly, but I'm not too sure about it. If it get stuck there, go to your gamedata, get to squad and goto ssp, goto wings and find swept. Then delete anything that has swept in its name. It may be my computer though.
