Not sure how to make this work, but I'm sure everyone together can figure it out!

I'm not sure what you mean here?

Someone made an excellent "Ground Assault" custom-made expansion on here. I've yet to try it, but it looks fun.

I hope you were referring to this:

Atmospheric only "ships" like the T-47 will be included in this game. They will be just like regular ships but be unable to be used in space combat.
