Not sure what it becomes. However, "Air Force One" is hardly a nickname. It's an official call sign for any plane carrying POTUS.Not to slight the Marines as in "Marine One" being the Presidents Chopper! When the President isn't aboard the 747 becomes "Flight 27000" unless it's changed since I was in Washington?Some other ATC nicknames....a medevac or air ambulance flight is called "Lifeguard"...could also apply as a prefix to an airline carrying urgent cargo, such as an organ for transplant.....
The most famous nickname...."Air Force One".....
Thanks for the update on the Tail Numbers, I guess 27000 is in the Ronnie Raygun Museum in California?
!
Also, the AF calls it a VC-25.
