I've heard it said that any plane the president is on is called Air Force One. But when the president uses a Marine helicopter, it is called Marine One, not Air Force One.
If that WAS a Navy plane President Bush was piloting, was it Navy One?
What we traditionally consider Air Force One is a Boeing VC-25A, the military version of the 747-200B. There are two of them, tail numbers 28000 and 29000. If the President is onboard, the plane is designated Air Force One. If he's not onboard, the plane is SAM 28000 or 29000.
The 'One' designation follows the President. Thus, his helicopter is Marine One only when he's onboard. Any naval aircraft that he would be in would be designated Navy One.
Airport takeoffs and landings by AF One aren't simply adding the plane to the queue, and it lands in line with everyone else. They basically end up shutting down the airport for about twenty minutes prior to it coming in, putting holds on takeoffs and landings. I did WAY too much research on this for my book. (I have the floorplans for both jets, too.)
