Flying the Free Skies with FlightGear - For those who want to try flying but can can’t afford their own private jet fighter check out FlightGear, an amazing open-source (and totally free) flight simulator.
The goal of the FlightGear project is to create a sophisticated and open flight simulator framework for use in research or academic environments, pilot training, as an industry engineering tool, for DIY-ers to pursue their favorite interesting flight simulation idea, and last but certainly not least as a fun, realistic, and challenging desktop flight simulator.
There are lots of amazingly realistic flying machines available for download, including SpaceShipOne and the NASA Space Shuttle!
