Here are some screenshots from the latest iteration of osgEarth integrated into Flightgear. Features include airport and runway lighting and surface clamped structures from TerraSync. Has some imperfections but overall works well. With all ground features enabled, can be a resource hog though so requires a capable machine and a good bit of memory. Only tested Windows 64 bit with 4GB Ram so far.
The functionality is near completion. Not sure there will time to get all complete and tested prior to 3.2 release but will attempt to get all cleaned up soon so that a merge request can be generated.
