FlightGear is a flight-simulator created by an international group of volunteers, and released as free, open-source GPL software. It has been used for academic research, education, and for fun. This build includes the internal Qt launcher. To launch FlightGear from a terminal window, run 'fgfs --launcher' from the command line. (This is how the .desktop file launches it.) If you prefer, you can install either fgo (python2) or ffgo (python3) as a more basic launcher. They will launch fgfs directly without the '--launcher' parameter. This package now includes the FlightGear-data package, so there is no longer a need to build two separate packages. flite is an optional dependency for voice communication (autodetected at build time). Note that the source has been moved from Sourceforge to Gitlab. NOTE: FlightGear will build and run in 32-bit, but you will most likely have to set your graphics settings fairly low to get any kind of decent framerate. BIG FAT NOTE: SimGear and FlightGear will no longer build on current because of incompatibilities in boost 1.87 (built fine with 1.86).
