12 Naked Machines that Look Cool InsideS

When I was a little kid, my favorite books were those full of illustrations that showed the guts of airplanes, ships, locomotives, space vehicles and all kinds of machinery. They still are. Machines' entrails are fascinating. Devoid of any skin, you can't do anything but marvel at human ingenuity.

Here you have some amazing and often surprising examples, including the photo above. What the hell is that Terminator about to kill someone, anyway?
