Since 1990, the presidential fleet has consisted of two specifically-configured, highly customized Boeing 747-200B series aircraft—tail numbers 28000 and 29000—with Air Force designation VC-25A. While these planes are only referred to as "Air Force One" while the president is on board, the term is commonly used to describe any of two aircraft normally used by and maintained by the U.S. Air Force solely for the president. The VC-25A is capable of flying 12,600 km (7,800 miles) — roughly one-third of the distance around the world — without refueling and can accommodate more than 70 passengers. Before these planes entered service, two Boeing 707-320B-type aircraft — tail numbers 26000 and 27000—had operated as Air Force One starting in 1962. Since its inception, Air Force One has become a symbol of presidential power and prestige.answers.com Marine One is the call sign of any United States Marine Corps aircraft carrying the President of the United States. It usually denotes one of 19 helicopters operated by the HMX-1 "Nighthawks" squadron, either the large H-3 Sea King or the newer, smaller UH-60 Black Hawk. Both are due to be replaced by the US101, a derivative of the AgustaWestland EH101. The first Presidential helicopter was used during the term of Dwight D. Eisenhower. In 1957, Eisenhower traveled on a H-13 Sioux military aircraft that lacked the air conditioning and lavatory accommodations of its modern equivalent. It was replaced by the H-34 one year later in 1958; the Sea King first flew as Marine One in 1961. Prior to 1976, the US Army shared the responsibility of helicopter transportation for the President with the Marine Corps, with the call sign of Army One while the President was on board. Today, Marine One is sometimes the preferred alternative to motorcades, which can be expensive and logistically difficult. The controlled environment of a helicopter also adds greatly to the safety factor. More than 800 Marines supervise the operation of the Marine One fleet, which is based in Quantico, Virginia, but is more often seen in action on the South Lawn of the White House, or at Andrews Air Force Base in Maryland. At Andrews, it is sometimes used to connect to Air Force One for longer journeys. Wherever Marine One flies, it is met on the ground by at least one Marine in full dress uniform. (Bill Clinton flew across the Grand Canyon in Marine One shortly before leaving office, and upon landing, was surprised to find a single Marine standing on the edge of the canyon.) As a security measure, Marine One always travels in pairs: One helicopter carries the President, while the other serves as a decoy for would-be assassins on the ground. To add to the tightness of Marine One, every member of HMX-1 is required to receive a top secret "Yankee White" security clearance before touching any of the helicopters used for Presidential travel.answers.com Army One : President Nixon on board Army One . Note the Army Sergeant First Class standing at the doorway, instead of the Marine as usually seen after 1976.Army One is the callsign of any United States Army aircraft carrying the President of the United States. From 1957 until 1976, this was usually an Army helicopter transporting the President. Responsibilty for helicopter transportation of the President was divided between the Army and the U.S. Marine Corps prior to 1976 when the Marine Corps was given the sole responsibility of transporting the President by helicopter. The most famous duty for Army One was on August 9, 1974, when President Richard Nixon delivered his famous "V" sign after resigning his office in the wake of the Watergate scandal. Wherever Army One flies, it is met on the ground by at least one Soldier in full dress uniform.answers.com Navy One is the callsign of any United States Naval aircraft carrying the President of the United States. There has only been one Navy aircraft to bear this designation, an S-3 Viking that transported President George W. Bush to the aircraft carrier USS Abraham Lincoln on May 1, 2003. That S-3 plane was then retired from service and placed on display at the National Museum of Naval Aviation in Pensacola, Florida on July 17, 2003.answers.com * * *
