I really dig Cross Sections
(the Star Wars Cross Section books are really neat and I recommend picking them up, or atleast flipping through em the next time you're at a bookstore).
Anyway, check out this awesome Cross Section of the Colonial Marine Dropship, as seen in the best movie ever made: ALIENS. The artist says on his site, " I am trying to use this artwork to secure a commission to illustrate a Cross Sections book about the craft of the Alien franchise." Oh sweet Jeebus, that would Rule. His illustrations are for sale, so someone buy me that Dropship, yo!
