I find it funny that; when you type in Battlestar Galactica in the Search bar on Lunch, various different topics pop up "Battlestar Galactica: The Plan", Battlestar Galactica: Razor" or Battlestar Galactica Daybreak". No matter how much you search you wont find a topic for the ship itself, the actual Battlestar Galactica.
Galactica is a 40 year-old Battlestar from the first Cylon War, during its service it has been under the command of many commanders Starting from Nash and ending with Adama. In the Colonial fleet Galactica is famous for being one of the only remaining Original 12 Battlestars still in its original configuration. An interesting Tradition followed by all of Galacticas Commanders was in keeping the ships original configuration Networked computers are not allowed on the ship.
At the time of the Fall of the Colonies Galactica is being Decommissioned and setup as a museum ship. It is once again is called upon to protect the human race from the Cylon threat. Galactica is an old ship and people eveywhere like old ships. Just check out how many visitors real life ships like the HMS Victory and USS Constitution get every year.
Its a nostalgia thing, same goes for Galactica. Not only that but its a cool ship, its tough and after all the years still is capable for protecting the fleet from the Cylons.
