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. On September 11th, the president's plane showed that it was much more than an executive jet -- it became a mobile bunker when all ground positions seemed vulnerable to attack.
In this article, we'll see what sets Air Force One apart from other
planes, and we'll find out what it takes to send the president around the world. With all of the things that Air Force One carries, it's no wonder the media calls it the "flying White House."
- "Air Force One" isn't technically a plane: It's simply the radio call name for any U.S. Air Force plane carrying the president of the United States. As soon as the president steps aboard an Air Force plane, that plane is referred to as Air Force One by the crew and all air traffic controllers, in order to avoid confusion with any other planes in the area. If the president rides on an Army aircraft, that aircraft is Army One, and whenever he boards his specialized helicopter, that craft is Marine One. Civilians generally refer to the physical plane itself as Air Force One, of course, and we will in this article too.
- Today, there are actually two planes that regularly fly under this designation -- nearly identical Boeing 747-200B jets. The planes themselves are designated VC-25A, with tail numbers 28000 and 29000.
The two planes have the same general structure as a normal Boeing 747-200B, and similar capabilities. They are almost as tall as a six story building, and they're as long as a city block. Each has four General Electric CF6-80C2B1
jet engines, which provide 56,700 pounds of thrust a piece. The top speed is between 630 and 700 miles per hour and the
ceiling maximum (how high the plane can fly) is 45,100 feet. Each plane carries 53,611 gallons of fuel and weighs 833,000 pounds fully loaded for a long-range mission. With a full tank, the plane can fly half way around the world.
Like a normal 747, these planes have three levels. But the inside, the plane doesn't resemble commercial 747s in the slightest. In the next section, we'll look at the major components that set the VC-25A planes apart from a normal jetliner.
[h=1]Inside Air Force One[/h]Air Force One has 4,000 square feet of interior floor space. Much of it looks more like a hotel or executive office than a jetliner, except for the
seatbelts on all the chairs. The lowest level of the plane mostly serves as cargo space. Most of the passenger room is on the middle level, and the upper level is largely dedicated to communications equipment.
The president has onboard living quarters, with his own bedroom,
bathroom,
workout room and office space. Most of the furniture on the plane was hand-crafted by master carpenters.
The staff meets in a large conference room, which doubles as the president's dining room. Senior staff members have their own office area, and the rest of the president's staff also has space to work and relax. There is a separate area for reporters traveling with the president, and there is plenty of room for the flight crew to do their work. All in all, Air Force One can comfortably carry 70 passengers and 26 crew members.
[h=1]Air Force One Special Features[/h]Because Air Force One carries the president, and because some trips can be quite long, the plane has a number of special features, many of which are found on no commercial airliner.
The crew prepares meals in two fully-equipped
galleys. They store a large amount of
food in freezers in the lower sections of the plane. The crew is equipped to feed about 100 people at a time, and the storage area holds as many as 2,000 meals.
The plane has a lot of technology in its onboard medical facility. The medical room has an extensive pharmacy, loads of emergency room equipment and even a fold-out operating table. The plane also has a staff doctor, who travels with the president wherever he goes. On every mission, the plane is prepared for a wide range of potential emergencies.
Unlike a normal 747, the plane has its own
retractable stairways, for the rear entrance and the front entrance. These stairways open onto the lower deck, and crew members and staff climb internal staircases to get to the upper decks. The plane also has its own
baggage-loader. With these additions, the plane never has to depend on an airport's facilities, which could be a
security risk.
The most remarkable feature on the plane is it's extensive electronics. It has 85 onboard
telephones, a collection of two-way
radios,
fax machines and
computer connections. It also has 19
televisions and assorted office equipment. The phone system is set up for normal air to ground connections and secure lines. The president and his staff can reach just about anybody in the world while cruising tens of thousands of feet in the air.
The onboard
electronics include about 238 miles of wiring (twice the amount you'd find in a normal 747).
Heavy shielding is tough enough to protect the wiring and crucial electronics from the
electromagnetic pulse associated with a
nuclear blast.
Another special addition is the
in-flight refueling connection. As with the B-2 and other combat craft, in-flight refueling gives Air Force One the ability to stay up in the air indefinitely, which could be crucial in an emergency situation.
Some of the most interesting parts of the plane -- it's advanced avionics and defenses -- are classified. But the Air Force asserts the two planes are definitely military aircraft, designed to withstand an air attack. Among other things, the plane is outfitted with
electronic counter measures (ECM) to jam enemy
radar. The plane can also eject flares to throw heat-seeking
missiles off course.
