^^^Thanks for posting that, Trevanian. It's funny how contradictory this stuff is. One source says there was a script, another says there was a treatment. Curiouser and curiouser.
Back to Bryant and Scott. Susan Sackett quotes a few of their memos. Here's a funny one.
An earlier storyline had the Enterprise emerging millions of years in the future. Ever the humorists, Bryant and Scott sent the following memo under the guise of Gulf and Western's chairman:
TO: GENE RODDENBERRY
FROM: C. BLUHDORN
It is my policy not to interfere in creative decision processes and this is merely to record my enthusiasm for the story which I read last week. May I, however, ask that in the final sequence when the Enterprise arrives at Earth several millions years in the future there be some indication that the solar system is principally owned by Gulf and Western. Nothing ostentatious, mind you, but just the subtlest of hints to this effect. Keep up the good work.

I don't think so. The "D" was inspired by a sketch of Andy Probert's of a ship with low slung flattened nacelles.
Back to the topic at hand...
