This web site emphasizes the addons created by the Orbiter French community. Small but active, our group has produced many excellent addons. So this is not an alternative to the well-known Orbit Hangar but an addition (most addons being present on both sites).

It also contains many Orbiter tutorials in French. You can meet all the authors of the French community on this forum (Most of them speak English quite well)

Orbiter is a completely free 3D space flight simulator. Written by Dr. Martin Schweiger, Ph.D, it has excellent graphics, but don’t see it as a simple shoot’em up… With a complex physical and mathematical engine, it can accurately reproduce real space journey conditions. From the Space Shuttle to the Millenium Falcon, through Apollo, Spirit, Huygens, Ariane and so on, Orbiter will allow you to pilot thousands of spaceships, from historical ones to the most futuristic, from the most simple to the really complex, on realistic trajectories to.... more creative ones.
