The Ultimate in Flight Simulation

There are flight simulators and then there is FlightGear. FlightGear is unique in that it is an open-source, multi-platform flight simulator. The user is invited to tweak the program and come up with new planes and scenarios. "Currently you can fly the 1903 Wright Flyer, strange flapping wing "ornithopters", a 747 and A320, various military jets, and several light singles. FlightGear has the ability to model those aircraft and just about everything in between." If you like to work with simulations and would like to take a crack at coding some new flight ideas, visit FlightGear.
