Re: The operational status of NCC 1701-A...?
There is no evidence to support that the Constitution Class was out of service by the time the Ent-B launched. We see debris that appears to be from a Constitution Class at Wolf 359. Which could mean that either one or more were brought out of mothballs or that one or more are still in service, all be it relegated to milk runs.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
