The "famous" Air Force One, which is a Boeing 747, is the largest American-branded commercial airliner available when they let the contract - both to show American prestige, and because they really need a huge plane. (Air Force One is the plane the President is in at the time, unless the plane doesn't belong to the Air Force; the S-3 Viking that carried President Bush to the Mission Accomplished speech was named Navy One while the president was aboard. This means that Air Force One can be any airplane; President Clinton used a C-9 to travel to Fort Drum, New York, in 1993 because a 747 couldn't land at Fort Drum's airfield in 1993, and while it was in presidential service it was Air Force One.)
As to the specific two planes - yes, there are two identical 747s - chosen...they were custom made for the government.
What else can I help you with?
Do airplanes repel gravity?
No. Airplanes don't do anything to gravity. a plane experiences the same force from gravity of any other object of the same mass, whether it is flying or on the ground. When a plane is flying the air passing over its wings exerts an upward force great enough to lift the plane.
What force of airplanes produced by engines causes air to move over and under wings?
Thrust
What forward movement force of airplanes provideed by ingines cuases air to move over and wings?
Thrust
How has the airplane changed over the years?
Airplanes have changed by going faster, larger and usable. Airplanes can be used for a load of stuff, other then flying one (1) person around
When the area over which a force is applied decreases what increases?
When the area over which a force is applied decreases, the average force applied over said area increases. In other words, the pressure (force/area) increases.
Is pressure a force, and how do they relate to each other?
Yes, pressure is a force exerted on a surface. Pressure and force are related because pressure is the amount of force applied over a specific area. In other words, pressure is a measure of how much force is distributed over a given area.
What force acts over the longest distance?
Gravitational force acts over the longest distance, as it is a universal force that attracts all objects with mass to each other.
What is a sentence using the word selected?
I selected a garbage-can over a banana.
Why are airplanes not allowed to fly over the community in The Giver?
No
For What forward movement force of airplanes provided by engines causes air to move over and under wings?
The forward movement force of airplanes is primarily generated by their engines, which produce thrust. This thrust propels the aircraft forward, causing air to flow over and under the wings. The shape of the wings, or airfoils, creates a difference in air pressure—lower pressure above the wing and higher pressure below—resulting in lift that enables the airplane to fly.
How has airplanes changed over time?
Airplanes has become extremely advanced since the first airplane in 1903. Modern day airplanes are more convenient and faster. They are safer and bigger.
What forward movement force of airplanes provided by engines air to move over and under wings?
The forward movement force of airplanes is primarily generated by thrust produced by the engines. Jet engines or propellers propel the aircraft forward, creating a flow of air over and under the wings. This airflow generates lift due to the shape of the wings (airfoil design), which causes a pressure difference between the upper and lower surfaces, allowing the airplane to ascend and maintain flight.
