If I query "flights overhead map" I get something that looks like this: 
But I've been completely unable to get Alpha to give me that same map for an arbitrary location like "Chicago". "Flights over Chicago" gives me a list and a sky map which is not the same thing. "Flights over Chicago map" doesn't do any better. "Flights over Chicago local map" gives me a map of Chicago without any flights.
Seems like I'm missing something fundamental! How can I get that map for an arbitrary location?
