new automa ground and air suitable for Simmars

[martintallon]

 I would like to see some ground vehicles similar to the moonbus from 2001 or land rams like the old battlestar galactica 79 series and some air vehicles for cargo and people like the various eagles from 1999 series or the firefly or the shuttles from "V" that actually work like the planes in an airport departing and arriving to a 1x1 or 1x2 tile that can be placed in an industrial zone or other area with attributes that add to shipping or transportation quotas in game. The examples I gave have many pictures on the web for details to design from. Vehicles should be scaled for cargo or a dozen or more passengers.  I found the models at foundation3d.com & artist3d.com but I have no idea how to create items.
