Sadly that one is gone but they did add Toronto's Billy Bishop as a detailed airport which I'd like to think is there as a worthy stand-in.
Is there a Buffalo Burger on Catalina Island?
Sounds like it is time for a Microsoft-Maxis partnership to give you a Sim to walk around town after you've landed your airplane.
No don't. It'd be then end of civilization as people would never leave their house (not that we can anyways:)).
How long until it's available as an easter egg? Would sure be cool!
Since the real airfield no longer exists, I can see why they don't include it. It really does need to be an Easter egg with 1980's Chicago skyline though.
I want to say that in Flight Simulator X, if you set the in-sim date sufficiently far back it would reappear.
