It's time to start getting fancy with the world view in AeroCEO.

The polygon outlines of landmass, and colors come from Natural Earth Data. I then ran it through a custom program to tessellate and convert it into a 3d model for rendering in game.
This is another good enough for now kind of thing. The 3D model will need a lot more processing work to look nicer, but alternatively I hope to find an artist to do a cool stylized version instead.
It has no effect currently, it just sits there looking cool in the background, while the airports are still on a flat 2d plane. But that will hopefully change very soon!
