Hello,
we are looking for people who will be able to help us voluntarily to develop in C++ an opensource flight simulator (called FlyLegacy) which will run under Windows, Linux and Mac OS.
http://flylegacy.cvs.sourceforge.net/viewvc/flylegacy/

Here are two screenshots and videos showing the progress of the project:

If you are interested by the project, please contact jean-sabatier@wanadoo.fr or post a message on our forum on http://forum.simvol.org.
Feel free to ask me questions if you want more details.
Thank you for your attention.
