The cockpit controls, scenery and weather particles are done well and with great attention to detail. It is obvious that the 3D designers took great care to make the landscapes and instrument panels as exact and accurate as possible. One of the best parts of this program is that you can download new models to use in X-Plane and because of that there is nearly infinite content available for this system.
There isn't any music to speak of in this program, but the sounds of the instruments and engines seem to be right on. Mostly these noises tend to blend together and become white noise -- but white noise that's specific to that craft. With this wide range of sounds you tend to get the feeling like you are really in the cockpit of an aircraft (even if that craft is on Mars).
