Re: Matt Jefferies and NCC-1017
It's true that Khan's schematic isn't clear enough to make much sense of it onscreen. It's too far away from the camera to make out more than the illustration. I can't find the screencap on TrekCore from "Trouble" for comparison, so it's possible that it was the same schematic reused. But I don't recall at what point in the ep Scotty is looking at it.
