The ADS-B transponder on the plane broadcasts the tail number (registration).
Whether it is physically on the bird or not.

That’s how I track planes from the Exec Stable as opposed to CIA birds.

that's a different issue\solution.

the question and issue being bumped around is: no tail number therefore fake ?

you framed it as such:

"There is one glaring problem and that is the lack of a “tail” number.
The Executive air frames have such number IDs not just on the tail but at eye-level nest to the entry door.
I don’t know of any Executive Stable birds without a tail number."

and i provided a source for the answer to the AF1 & AF2 birds...
also some tail numbers are on the fuselage some are on the engine cowl if it's a rear engine.
