Hey, check out this
page which has drawings of Star Trek, Star Wars, and Babylon 5 ships to scale, compared to real ships and buildings. There's the Empire State Building, Eiffel Tower, Statue of Liberty, etc compared to Godzilla, Battlestar Galactica, Galaxy Class Starship, Omega Class Destroyer, Star Wars Space Slug, etc.
Each drawing is scaled to 1 pixel = 1 meter.
