Microsoft Flight Simulator
Microsoft Flight Simulator is a series of amateur flight simulator programs for Microsoft Windows operating systems, and earlier for MS-DOS and Classic Mac OS. It was an early product in the Microsoft application portfolio and differed significantly from Microsoft's other software, which was largely business-oriented. In November 2022, Microsoft Flight Simulator is the longest-running software product line for Microsoft, predating Windows by three years. Microsoft Flight Simulator is one of the longest-running PC video game series of all time.
