LOL - thanks Psion
So I was reading through the Ariel carrier thread and the most recent post was about the ~950 feet Enterprise in a diagram seen on the show.
I tracked it down to "The Enterprise Incident", measured it out and well, there you go, a ~950' Enterprise!
However, there are some interesting parts that don't match up to the filmed model(s) which I might use as reasoning that this ~950' model represents the original design/version of the Enterprise before Pike took command. This version would be the what the Enterprise looked like when it first was constructed. Then the version we see filmed in the series happens to be a slight redesign and refit, perhaps larger than the previous version. And the version we see in TMP is another larger redesigned and refit version.
Sounds a little crazy, I know
(Or out-of-universe explanation: I'm using the Matt Jefferies graphic that made it into the episode as the reference to a "pre-Pike" ship that was ~950' and because of the differences with it and the filmed model there is some wiggle room to consider the filmed model to be a redesign like the TMP version and thus I could make the filmed model larger and still be Thermian about it We have some precedent in the movies where internal graphics on the refit-E still show the older TOS graphics so why couldn't the TOS version show pre-TOS graphics? )
