If you are like me and purchased the "Classic" version of USAF, you did not get a hard copy of the manual. Well, I am happy to report that you can still get them directly from Electronic Arts! All you need to do is write them and send a check for $5 to:
P.O. Box 9025
Redwood City, CA 94063-9025
Attn: CD Classic Manuals
It took about a month for me to get my copy. The copies are also only availabe as long as supplies last. I am sure most of you will agree that having a hard copy of the manual is invaluable if you are just learning the game.
