In response Camille Faith to her Publication
Devil's advocate:
1) The official AF1 is being refurbished and debugged, as Minkeywerx tells us happens between administrations.
2) Am I correct that any plane occupied by POTUS is designated AF1?
And I don't like playing Devil's advocate about these sorts of things and hope someone opens a can of whoopass and debunks me with extreme prejudice.
2) is correct. AF1 is a call sign that implies "this is important because it's the president's" it is not a title for one specific plane.
