Planes, Trains, and Automobiles

This just crossed my mind, but are the devs planning for planes and trains? Or even tractor trailer support, because I like hauling stuff.

 

Gabester said he's going to build a truck (Like a tractor trailer without the trailer. Not really sure what to call it ), so I'm hoping that means trailers. I have a dying urge to haul a bunch of cars on the back of a trailer and see how realistic the physics are. Trains will probably be covered by the community. As for planes, I want to know REALLY badly whether the game will include them. I'd love to see some planes with realistic physics and damage. I don't want to see a plane with the same physics as cars, but one that will actually explode on impact and disintegrate. Also, I'm curious how helicopters will react to these physics.

 

Im not sure about trains or planes, but in another thread they were highligting the trucks hitch so i believe trailers will be in.
