He said it was the only fully functional / operational ship not connected.Question for a member who has no interest in watching this, and only looked up things to see what was happening and watch cool shots: Geordi said the Enterprise D was the only ship not connected like all other Starfleet vessels were, leaving it uninfected. So … what about other shops in the museum? Like Voyager. Like the Defiant (which was made to battle the Borg, for goodness sake). Aren't those, also, you know, not infected?
Meaning that at best the other ships in the museum are not fully functional in any number of things..IE The E-A probably doesn't have antimatter onboard, same as the others..they're not fueled and armed any longer, etc.
