Remember the Jumbo Jets from GTA: 3 and VC?
They were planed to be in SA as well, but, unfortunately, they were removed. With this mod, they have been added back! It may not be the SAME places as in the BETA version, but it still looks nice! 
You may also notice some body parts in front of the Jonson house and hanging cops on the wall on the outside, if you want those gone, then just simply use map editor to remove them!
