Note: Obviously if this picture were a sci-fi spaceship it would be smaller than a breadbox, click HERE for the full-res poster. Also, keep in mind one pixel = 10 meters, so any ship smaller than that probably didn't make the cut.
This is a visual size comparison of sci-fi franchise spaceships compiled by DeviantARTist Dirk Loechel (links to more info about all the ships included). Is he missing any? I bet you can probably find one. That's because you're a pro. A pro at pointing out flaws. You and I should go out sometime and talk shit on everyone else at the coffee shop. Not loud enough for them to hear though, we're not bullies.
Thanks to Ford, lukas, RI and Brainjam, who agree spaceships are the coolest kind of ships.
