I have created a few ships that I only want my aliens to be able to use. They are all set to be nonfunctional so that my traders can only sell em. There is no alignment, exp, or corp requirements set for the ships. I based em off of the Mule, and set them for alien use only, then set the aliens to that specific ship type : Combat I, Cargo III, Transport III, and Scout I.

My problem is when I check my available ship list none of my aliens are able to get into the ships.
