Umberto this is the greatest airport scenery I've seen so far, and you're not even done yet. Simply amazing. I do feel bad though, that you'll more than likely have to remake O'hare yet again in another 8 years, as the terminal construction is just beginning and is scheduled to be complete by then.
Out of curiosity, does your new version have the 5 new stinger gates on the L concourse of Terminal 3?
Best Regards!
