Readme:
Create a new folder, Highwind in your art/units folder and unzip all the files to that folder. Then copy and paste the HighwindLarge.pcx and HighwindSmall.pcx into your art/civilopedia/icons/units folder. Then open up the Highwind32.pcx with an image editor, back-up your units_32.pcx and open it with an image editing program. Paste the image into a square at the end of the other icons, be sure to line it up correctly. Then backup your PediaIcons text and Civilopedia text, copy and paste the appropriate text below into its respective places. Finally, open up your scenario in the civ3-editor and add the unit (if you need help with this part, look around in the tutorials forum, I made this quick tutorial because some people organize their units differently).

Enjoy! 

Note: This unit has two different victory sound effects available, one is simply the sound of the jets as the unit spins, the other is the Final Fantasy 7 Victory Fanfare. The default sound is the jets, to change this simply open the Highwind.ini file and under Sound Effects, VICTORY simply change HighwindVictory1.wav to HighwindVictory2.wav

^
^ The pinnacle of airship construction, The Highwind is the mighty flagship of the airforce. Using its multiple massive jets The Highwind can break the sound-barrier, easily making it the fastest airship ever constructed. The Highwind has two multi-missile racks capable of unloading enough missiles to effectively level a city block in seconds. It also contains room for transporting troops or small vehicles and systems to allow generals to use the airship as a temporary command base.

^ The Highwind airship was designed for the Shinra corporation by its ace airship pilot, Cid Highwind. After Cid's dreams of space travel were repeatedly crushed by Shinra, he joined the AVALANCHE resistance group. Shortly after joining, Cid was able to convince the airship's crew to mutiny against Heidegarr, their current abusive commanding officer. With the aid of the airship, AVALANCHE was able to defeat Diamond Weapon, saving Midgar from certain destruction, as well as defeat Shinra for good and put an end to Sephiroth's evil plot.
