Here's a site a friend of my pointed out to me recently. It compares the scales of a lot of the ships from not only Star Wars, but also from Star Trek, Babylon 5, Independence Day, Robotech, Starship Troopers, Battlestar Galactica, V, Titan A.E., and even some objects from the real world! They even throw in King Kong and Godzilla! You can even drag each ship/object up against any other to get a side by side comparison! Check it out!
