The registry numbers have never made any sense. Anyone who says otherwise is talking nonsense.
Its a bunch of numbers.
Real-worldly - I seem to remember it being Matt Jeffries 17th attempt at a design, but in the Star Trek world there has never been any explanation of how they work. If he had changed the number, Abrams would have been set on fire by an angry pointy-eared wearing mob.
I thought 1701 was the registry on Jeffries' plane.
That seems to ring a bell, but it rings a bell of not being true. I'll have a look in my Star Trek books when I get home tonight. I'm sure it was his 17th pass, but I might be wrong.
