Viper 1104NC was the craft flown by Joker in the first sortie against the Cylons.
Kara Thrace flew 1104 during the Battle of Ragnar Anchorage, presumably since Viper 8547 was damaged in the earlier engagement. (Mini-Series)
1104 was also flown by "Hot Dog" Constanza during a training flight with his fellow nuggets and Lieutenant Kara Thrace. It was heavily damaged during the subsequent battle with eight Cylon Raiders. Constanza ejected from 1104 during the battle (You Can't Go Home Again).
