No, I didn't. Being a picture on the wall does not make it "on the show." To clarify, the ship was not a main setting on a show like the NX-01 was.You must have missed the part where I said it was.
The ringship appeared in the ENT episode "First Flight". There's a picture of it on the wall of the 602 Club.
As far as Star Trek history goes the ring ship is as important as the aircraft carrier.
Now, I'm not saying this a good reason per sey but it is a reason to see that acknowledgement happen.
