In Chuck Yeager's Advanced Flight Trainer you have the chance to test pilot 14 different airplanes, such as the Bell X-1 and the Lockheed SR-71. It features 10 different viewpoints both inside and outside of the plane, with a zoom of up to 256x, and different aerodynamics for each plane.
You can do different things with the planes, from racing against a computer opponent, to practicing formation and stunt flights. You can follow the testing and development program through its evolution.
There is a "black box recorder" to replay your flights, and analysis of your performance compared to an ideal one.
