I thought in G3 you could fly the entire "earth" and never reach the end. So far, I still have the same limitations as G2. I run into solid white emptiness in very short order. The graphics otherwise seem fine and my frame rate is quite high. Is there something I should toggle on/off to enable unlimited terrain?

I was informed on the Knife Edge forum that some airports do not support unlimited terrain and some do.

The Sierra Nevada terrains seem to go on forever.
