Exhibit: Can I learn to fly in a flight sim?
What's the same?
First of all, airports and navaids are in their correct positions and elevations, and larger airports (including ORH) have proper taxiways and lighting in addition to correct runways. With the TerraScene scenery, the waterways (lakes, ponds, and reservoirs) look about right, as do the major roads. Urban areas look urban, and fields and forests look about right too.
Other than large radio towers, there aren't any structures or buildings (though you can add some with the FLY!Editor if you like -- it's easy, but so far I've only added a few buildings at ORH and a radio tower that disappeared from the FLY!default set when I placed the TS scenery).
