By this definition, the Excelsior is also the Enterprise, or that (nearly) all boats in the world are the same, which is true from a certain point of view, but it's also pretty meaningless. Yes, the outline of a canoe is pretty similar to the outline of a yacht which is pretty similar to the outline of a supertanker, and... they still aren't the same at all, even if Joe On The Street says they look the same. It doesn't take a car expert to tell the difference between an old VW Bug and a new VW Bug, but even if it did, they aren't the same.OMG. talk about splitting hairs. Sorry to get into this convo but I've been following along and arguing that they drastically modify the silhouette of the Enterprise is pretty much the definition of pedantic. As stated above, it's a saucer, and 3 cylinders connected by a neck and two pylons in pretty much the exact same configuration as it was in the '60s, only with the addition of an angle to the pylons and a slightly shorter neck. You show that to anyone on the street and they will recognize it as the "Star Trek Enterprise".
I (mostly) like the Discoprise, but to say the silhouette (let alone the details!) is the same as the TOSterprise? Nope.
