Coming Summer 2007:
Steeda On a Plane.

In all seriousness, include tons of details and even include sidework ou've done for free (CEGer's brakes come to mind). Even though it is not something that flies you are still showing your ability to work on more than just one thing. Maybe a a vehicle will break down when you need it for the job?
I could think of more, but I'm out of Energon.
