To try it out, download the java bytecode, unzip the archive, and navigate to the directory containing the extracted files. To start the simulator, double-click on the fc.bat file.
This assumes a Windows PC with the Sun Java run-time installed (I have version 6 update 6). There is a readme.txt file explaining the key functions. No vario sound, but otherwise it works fine. Enjoy Flight Club even when you are off-line !
