Some mountain airports might be quite interesting with 3d terrain

But that's not what this is. Here only the airplanes are in the third dimension. The world map isn't even a globe

still working on adding a custom terrain map, so its more realistic to view, while the globe part is just pure skill issue, i tried a few different approaches but wasn't able to code that in

My local airport is at 1417ft MSL, so the planes start and land in mid-air.
