What are those little yellow and blue planes I see in flightgear? Are they some kind of default generic model of planes that haven't/can't be loaded?
As I understand it, in order to see a plane in mp, you must have a model of the plane on your own system. I don't see them on my aircraft list, and when I try and figure out what they are from the pilot list, ... well, I can't.
So I'm thinking they're "proxy models" for planes that aren't/can't be loaded. But then why aren't they used for all planes in the area that don't exist on the system.
Or are they hacks?
