September 10, 2010 - Atlas Air Worldwide Holdings, Inc., a leading global provider of air cargo assets and outsourced aircraft operating solutions, confirmed on Thursday that the U.S. Air Force will be extending its contract with Atlas Air, Inc. for the flight training of Air Force pilots and flight engineers who fly the Boeing VC-25, also known as Air Force One, and the E-4B National Airborne Operations Center through 2011. 

Air Force One is the official air traffic control call sign of any United States Air Force aircraft carrying the President of the United States. In common parlance the term refers to those Air Force aircraft whose primary mission is to transport the president; however, any U.S. Air Force aircraft may carry the "Air Force One" call sign while the president is on board.

Atlas, Titan and Polar offer a range of air cargo and aircraft operating solutions that include ACMI aircraft leasing ? in which customers receive a dedicated aircraft, crew, maintenance and insurance on a long-term lease basis; CMI service, for customers that provide their own aircraft; express network and scheduled air cargo service; military charters; commercial cargo charters; and dry leasing of aircraft and engines. 

The "Air Force One" call sign was created after a 1953 incident involving a flight carrying President Dwight D. Eisenhower entering the same airspace as a commercial airline flight using the same call sign. Several aircraft have been used as Air Force One since the creation of the presidential fleet.
