I wouldn't trust the FS
that much for airports out of North America or Europe, Espion007.
If you have no detailed sceneries, in many places the game will show things very far from what they really are.
In my country, for example, the FS
puts several airports in the top of very high hills, like above the rest of the terrain, when there really is no hill at all.
In any case, I don't think that in the middle of such a wide plain rain-forest there would be such a pit, and precisely an airport located inside...
