X-Plane - Advanced Flight Simulator For Linux PCs

[mnajafi]

you always wanted to fly but were held back by the expense and risks of flying real airplanes, you may want to give X-Plane a try. It is one of most advanced flight simulator software packages for personal computers and includes complete scenery of the planets Earth and Mars. X-Plane creates a realistic flight model by computing the forces to act upon each part of the aircraft. A wide range of aircraft are available, and you can build your own.
