As a linux user since 1995, I have found the documentation to be little more than it was around 2000. It's easier to do a google search than try to find an answer in a man page. Not only that, the man page rarely has useful examples, one of the biggest problems.
If it's a Linux based fighter it will never crash, fly well, but be missing key features like a fuel guage and gun sites. Oh, and there will be no stick to control the plane, but you will have a command line and scriptable flight controls.
