Is this some sort of picture-book post to teach newbs how to build airports?
Doesn't seem like much other than that.
Please consider actually going farther than placing a few baseplates for your build before posting it in the Gallery.
It's like that guy that made that office building whose only support beams were a couple panes of glass and where if you wanted to ascend/descend floors you'd have to blow a hole in the building.
Uh, where's the terminals, taxiways, and gates? And why are there only 32x32 spaces instead of hangars?
