I would like to clear up many questions.
The andromada is real, for those of you with a Xploder V5 cheat disc the name in the menu is is Airliner 2. You can put the back down on the cargo bay, but cannot enter it. it is very easily controlled.It cannot be found anywhere on the game that i know of, so i assume rockstar made it a cheat only vehicle.
Fow those of you with gameshark, ARMax, etc the code is:
when this is active simply press in game
cheers for listening
