Copied from the speculation thread last week:
I guess now that they know SF is compromised the best place to discuss the next steps - and even take those steps - is in a museum ship
Imagine the possibilities: Changeling spies everywhere, so they take the museum ships out... each of them commands one... and we see all of them, the A, the Excelsior, the recovered D, Voyager, perhaps even NX-01, fly out and go on one last unexpected mission!
"Sir, someone is stealing the Enterprise! And the other one! And Voyager!"
I know you're just being tongue-in-cheek, but to think that any of those ships at the museum are in any way functional enough to fly would be the ultimate suspension of disbelief.
