Re: Admiral Adama
Adama was the commander of the only remaining Battlestar warship. It was used in a previous war with the 'Cylons' (a robot like race) and Galactica was due to be moth-balled as a museum piece. As such it was not retro-fitted with up to date kit that was networked together and with a central mainframe for efficiency. Adama, as a veteran himself distrusted such intercommunication between devices. His distrust was dismissed as being anachronistic and paranoid.
Sure enough, the Cylons returned, compromised the mainframe and pretty much instantly disabled/destroyed the entire defence system apart from Galactica.
