Air Force One is a prominent symbol of the United States in general and the office of the presidency in particular. Whenever the president travels overseas or across the country, he takes his high-tech deluxe jumbo jet with him. Air Force One is maintained and operated by the Presidential Airlift Group, part of the White House Military Office. Air Force One also has quarters for those who accompany the President, including senior advisors, Secret Service officers, traveling press, and other guests. Several cargo planes typically fly ahead of Air Force One to provide the President with services needed in remote locations.
