AirForceOne is an extension of the White House and other government buildings/offices afforded the use of by the sitting incumbent. The aircraft belongs to the people of the USA and is flown, operated and maintained by government military people in this instance the Air Force.
The aircraft is an extension of the Office of the President, primarily defensive, not offensive and is equipped with defensive functions to protect the holder of the highest office in the government of the U.S.A.
There is a second "clone" of this aircraft which is a look-a-like and either one can be in use by the President - accompanied usually by F-16 fighters even over domestic airspace.
I doubt if any sitting president would understand all of the workings of AirForce One but the staff operating the craft would be of the highest responsible reputation for
maintaining his safety, accurate communications in and out, and destination certain.
