For those that don't wanna read the entire article,
this should suffice:
The Boeing E-4B Advanced Airborne Command Post, with a project name of "Nightwatch", is an aircraft operated by the United States Air Force and is specially built to serve as a survivable mobile command post for the National Command Authority (the President of the United States and the Secretary of Defense, and successors).
Anyone else gets the chills from that idea?
