Thanks. That image of the saucer was what we called the "Planet Of The Apes" or "Statue Of Liberty" shot when we came up with the idea; we just put it at the beginning of the show instead of the end.
Jimm and I just got to talking about "what could we do that they never did on TOS but that they might have done?" that would still fit in to that milieu. This was one of those things.
I never had that specific discussion with Jimm, but I was thinking the same thing when overhauling "The Atlantis Invaders". I made a mental list of things, visual and plot-wise that I always wanted to see on TOS and never did. There was a space battle in the script, but I think I was successful in giving it a twist that made it pretty unlike any aired Trek episode in how it played out.
