I was hoping you guys can help. In "All Good Things" the Enterprise D has three warp nacells. Can someone explain why please?
Also, in the episode where they meet an Enterprise from the past and it goes back with Tasha Yar on a suicide mission to fight the Romulans and defend the Klingons, which Enterprise is that? I believe that's the Enterprise C.
Finally, I believe the Enterprise B is not an Excelsior class starship. Any comments?
Thank you all!
