Bots and tanks are built on land. Sea factories are in the sea. Orbital factories are in orbit. Why aren't the air factories in the air? Much like orbital, the basic factory may need to be on land for logistical reasons, but surely the advanced air factory could be flying? Sadly, although the principle of non-land structures has been proven in orbital, setting the advanced factory to WL_Air makes it unbuildable (no build outline) I can force it with the sandbox tools, but it's still sitting on the ground. I can get it to take off by treating it as a mobile unit (complete with movement), but that involves removing the UNITTYPE_Factory attribute, which causes it to try and build units at specified external locations, instead of inside the factory (and fail, at that)
