I like to imagine Paris One
as having the words PARIS ONE
written across the hull, with the Federation emblem painted in bright, vivid blue directly below it where we're used to seeing the registry number.
If it's analogous to Air Force One, that wouldn't work.
I'm aware. But I'm positing that Paris One
, being italicized like any ship's name, is not a call sign for any ship bearing the President, but rather an actual name for the ship.
Like I said, it's what I'm conjecturing for myself. I make no claims about what it actually
is. But that's how I like to picture it.
