We also have XP Home and we loaded aircraft by downloading the aircraft zip folder off the website and into "My Documents." We then went into "My Computer: C//Drive: Program Files: IPACS: Aerofly Professional ...: Aircraft" When you open the aircraft folder you will see folders for each of the airplanes already installed in the game.

Go to the file drop down menu at the top of the screen, click new and click "new folder." When the new folder comes up, name it the exact name of the aircraft you want to download (ex: cap231; funtana, etc).

Close out of My Computer by clicking on "My Documents" on the left side of the screen box- open the zip file for the airplane you want, open the aircraft folder inside, until you see a bunch of icons for the craft- wing, a tmd file, etc. Hold down the Ctrl key, as you click on all of the files (we didn't do the read me file) with the mouse (this will select multiple files at once); right click and select "copy."

Return to My Computer: C//drive: Program Files: IPACS: Aerofly Professional ...: Aircraft: the aircraft folder you previously created. Once you have opened this aircraft folder, go up to the menu taskbar at the top and under edit, select "paste." You should see all of the files you just copied from the zip file download into this file.

Close out of the aircraft folder and launch the game- go under aircraft and you should find you new airplane
