X-Plane is a flight simulator produced by Laminar Research. A desktop version is available for Mac OS X, Windows, and Linux, while a mobile version is available for Android, iOS, and webOS. X-Plane is packaged with several commercial, military, and other aircraft, as well as basic global scenery which covers most of the Earth. X-Plane also ships with other software to build and customize aircraft and scenery. X-Plane also has a plugin architecture that allows users to create their own modules, extending the functionality of the software by letting users create their own worlds or replicas of places on Earth.
, the most recent version is X-Plane 10.45. X-Plane 10 comes in a cardstock or tin case on eight dual-layer DVDs, most of which comprise the global scenery, which is compressed. The scenery spans from 70 degrees south to 74 degrees north. Switching the planetary model to Mars is an option that comes with X-Plane 9 only, and although the atmosphere is thin, flight is possible.
