Remember my post when I highlighted the Starship Comparison Chart in this blog (in case you can't, its HERE). Well, I managed to get an updated version as of October 2010. Neat huh, that someone is actually updating these to reflect on the newer shows and compare them to the older ones.
Anyway, here they are in case you're wondering how big these ships are in comparison with their "peers"
A special thanks to Dan Carlson for making and updating these.
