Who knows Ottawa ? Located in the province of Ontario across three rivers, this capital city has a very nice airport - Macdonald Cartier, with two runways. Obviously, it is connected to major canadian and quebecan airports ; Toronto, Halifax, Winnipeg, Calgary and of course, Quebec, Montreal etc.
Heading to the north, there are flights to Iqaluit or St John's. To the south, it is linked to N-Y, Philadelphia...
Note that Ottawa is also offering flight to Europe, London et Frankfurt.
Why i am writing about that ? Because John de Young designed months ago a very good airport with 3D max, incorporating custom lights (nice night lightings !), animated jetways and detailed surroundings (parking lots, road traffic etc.).
This scenery is free and downloadable on flightsim.com (on last check). CYOW is either available for FSX and FS 2004 and you can make nice FREE flights between Ottawa and Philadelphia (check our link about SunSkyJet).
