What a coincidence! I discovered those models just yesterday! I managed to open the Shuttle model in Blender, so I guess it would be possible to have them exported to Flightgear. BTW, here's the link to the site: http://www.nasa.gov/multimedia/3d_resources/models.html Regards, Fabián On Sun, Se

[Flightgear-devel] Optimal desktop processor/graphic card

Hi, I'm planning to buy a new desktop PC and I want to be sure I will be able to run FG smoothly (I may also be doing some video editing, but that's for another forum).

Hi, I'm planning to buy a new PC with operating system. Is there any OS that is not supported by FlightGear? I want to be sure I'll be able to compile and run FlightGear. Is Windows 7 64-bit supported? Or should I better stay with Windows 7 32-bit. Please Linux people don't laugh at me :( Thank y
