1. You can load the backgrounds from the Aircraft Carrier into any
 graphics package in the .LBM format and spray all the walls with raffiti.

 2. All files in the DG directory can be swapped around. Therefore you can
 fly an F-16 - frigate - truck etc. by typing:  REN AV-8B V8B.BAK and then
 COPY TRUCK AV-8B. Load the game as usual and take off. Now, when you switch
 to an external view you'll be flying a truck!
