Trivia

In Champaign, Illinois (a city southwest of Chicago), if you have scenery complexity set to Very Dense, you will find a small, flat red building. Fly in (actually, slew in, or have crash disabled) one of the entrances. You will see a wall with credits and a picture of the development team (and guess where you are - the subLOGIC main office).

In FS 98, the building is still there, but the wall inside is gone.
