I've just found this and it could be of use to some of your schools/colleges/universities. Orbiter is basically a space flight simulator that allows you to fly the shuttle, apollo and experimantal/prototype ships, and is free under GPL (Windows only I'm afraid though).
Enjoy: Orbiter Space Flight Simulator
