The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. It also simulates space flight in Earth's orbit.
FlightGear's flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to the standards of the space industry. FlightGear is used professionally for research and development, as well as non-professionally.

I'm sure you already know, but Google Earth's actually had a really basic 'flight simulator' built in for a while now: https://support.google.com/earth/answer/148089?hl=en In gaming or technical terms, it's not much good as a game per se (or at least, wasn't when I last tried many years ago) but is still quite fun when playing around familiar areas, getting an idea of various flight times. - Source: Hacker News / about 3 years ago
