Unfortunately, programmers with sufficient OSG and FG knowledge are very thin on the ground. Tim Moore is the guru, and best placed to say how difficult this would be, though I've spent some time working on the graphics as well. >From my experience adding a new terrain engine such as osgEarth would be a very large job indeed. As you have shown, we have plenty of room for improvement in our existing terrain and graphics engine. Personally, I think my efforts are better spent improving our existing graphics, which will benefit both low altitude and sub-orbital flights, rather than integrating a new terrain engine. Going off-topic: one thing I have been thinking off is generating lower resolution BTG terrain files using terragear and then loading different resolution files depending on distance. So tiles far away would use a lower resolution height map and wouldn't include line and point features. I've still to investigate to see if this would make any real difference both in terms of I/O and graphical performance.
