McDonnell Douglas DC-9-15 made by @bushiido444 as an add-on.

*This plane contains one "Aero California" livery and can not have multiple liveries at once.

*Credits to @bushiido444 for the livery.

Changelog:

V1.1: Changed the vehicle sound to what it's supposed to sound like.

*I accept vehicle add-on requests.

NOTE: By this I mean I can make an add-on version of a modded vehicle that already exists as a replace vehicle. Unfortunately I don't know how to convert models and such.
@SkylineGTRFreak however, has a website in which he listed all his upcoming models he's gonna convert, which can be found here: http://acfreakssanandreasmods.blogspot.com/
