As Hagar has said...
...a salutary warning to look after all your original Flight Sim disks, and keep them safe in their original jewel cases!
The day is rapidly approaching when they may no longer be available on the Game shelves!
My original copies of CFS 2/3, FS '98, 2000, 2002, 2004, and FSX are all safely tucked away ( in Fort Knox?) for the future!
Purchase a new copy of FSX, while you still can!
