If the Gyro-Balanced Khorium Destroyer wasn't the crown jewel of the Engineering profession, the Turbo-Charged Flying Machine surely must be. Also a serious tax on either time or money to create, this machine will allow the player to travel at speeds comparable to any epic flying mount available in-game. Unfortunately for you non-engineers, this item requires engineering skill to operate.
I especially like the added touch of the dashboard-mounted Hula Girl Doll, which adds a nice effect. Also, it's a good thing the Outlands doesn't have an EPA because they'd be throwing a fit about all that pollution!
All in all, engineering is an amazing profession of specialized armor, handy trinkets, fun pets, powerful explosives, super-cool guns and ammunition, and turbo-speed flying machines. As I reflected once, now all we need is a submarine!
