Behold, the map of Ferris Aircraft ... on a very busy day.
Click on map to see it in excruciating detail.Looks like, while Green Lantern and Sinestro slug it out in the skies, Star Sapphire is focused on protecting Ferris Aircraft property with force fields. Why, it's almost as if she owned stock in the company! While the map certainly looks busy, there's really not a lot going on terrain-wise, because the map is entirely aerial; no non-fliers or objects allowed!
However, there are some obstacles up there in the wild yellow & green yonder. Clouds providing hindering terrain to lurk in and residual constructs from the battle (the hand, the boxing glove, and brick wall) serve as blocking terrain. I was going to include the helicopter as blocking/hindering terrain, but that would simply occupy too much of the map, so I left it "below", .
Because it's in the air, all your figures must be fliers or be carried by fliers. Of course, a Green Lantern can carry 8 passengers, so you might want to take advantage of that Team Ability! But that's pretty dangerous; knock out the flier and any of his passengers fall to their doom, er, I mean, their KO.
I tried hard to get an aerial feel for the map by creating an impression of three-dimensionality; how'd I do? This was an experiment and I'm interested knowing in what you think worked well... .
