The United States Air Force is using the Gulfstream III as a military aircraft. These aircraft are used to transport the President of the United States and the Commander in Chief during wars or crises. Air Force One is the name of the aircraft when the president is aboard. They often land at an Airbase within an hour from the President's place. In case of a serious emergency, the plane will drop off the President at a command post on the ground.
Although the Gulfstream is a large plane, it is not the largest aircraft in the world. It's also not expensive. However, it is not the most costly. As well as anti-missile systems, satellite communication systems, and large press briefing rooms, a shower facility and showers are essential. Security requirements include self-defense electronics as well as a jamming device.
The United States is looking for large aircraft to be manufactured in the United States in case of conflict. These include C-5s, C-20Cs, and the C-32A. Initially, only two of these aircraft were expected to be procured. A study done in August 1993 found that the USAF could exercise its option to purchase half of the available 120 aircraft.
At first, the air force was worried that a commercial airline would be able to carry the president. The aircraft were eventually handed over to the Air Force Reserve as well as the Air National Guard. A number of these aircraft were transferred to the Air Force System Command (US Forest Service) in the following years. Many of these planes have been converted into presidential transports.
Until recently, the aircraft were known as C-20Cs. The aircraft were previously registered to the Department of the Air Force Washington, DC under N770GA. The aircraft was transferred to AMARC at Boeing Cecil Field in Jacksonville, FL on April 29, 2010. The aircraft was reregistered with QF-16C after the transfer.
The antenna that can reach eight kilometers extends from the aircraft's nose to the ground. It can also be used for communication with submarines. Some aircraft have high-frequency radio communications antennas. Communications gear includes 85 telephones with different antennas and a jamming mechanism to protect the aircraft's from anti-aircraft weapons.
Before the Gulfstream III, the aircraft was known simply as the C-17. This name is derived from the famed C-17 Globemaster II that was built and flown in the United States Army Air Forces. In 1949, the first flight of this aircraft was made. The C-17 was eventually renamed Spirit of Charleston.
The aircraft comes with a pressurized cabin that has a square cross section. Seven lavatories, an emergency station and a freezer with 1,000 Ib (or 454 kg) of frozen food are included in the aircraft's main cabin. For parachute drops, the ramp can also be lowered while flying. Many of the aircraft are made out of aluminum alloy. Composites will be used for the landing-gear sponsons and control surfaces as well as landing-gear doors and landing-gear windows.
FAQ
What is the most mysterious area on earth?
Antarctica is home to the most mysterious and remote place on Earth.
This is why we find it so captivating. Because it is unlike any place on Earth.
It is very remote and isolated. There is much more to this place than meets the eyes.
These wild animals are also found in this natural wonder.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
Antarctica's name is a mystery. Others believe it means "land with ice". Others believe it derives from Greek mythology.
Antarktis, the Greek name for the island on which Zeus' twin brothers were conceived, was used in ancient Greece. According to legend, one twin was born in winter. The term antarctic is derived from this.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would mean that the land was turned away by the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the highest, coldest, windiest, dryest, and most populated continent. It is too cold to support trees, plants, and animals.
Yet, this frozen wasteland is alive.
It houses approximately 90% of all Earth's living organisms. There are about 50% of the world's animal, plant and plant species.
What is it that makes Antarctica so unique? Here, water freezes and becomes ice instead of evaporated into the air.
This results in large masses of ice floating above the ground.
These glaciers cover more than 80% of the continent. And they're growing larger every year.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting goes on, the sea level may rise by as much as 200 feet. It could result in massive flooding all over the world.
This does not mean that everyone is wrong. Some scientists claim that global warming could be good for us. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others cautioned that this theory sounds too science fiction.
How does the brain regulate the functions of the body?
The brain sends messages to other organs and muscles to ensure they work together. Everything that happens within your body is controlled by the brain. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made of billions, or neurons, of nerve cells. Action potentials on Axons are an electrical signal that neurons send to each other. Every neuron has an outer cell membrane that surrounds its nucleus. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. The neuron fires when there is ion movement.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. In turn, the second neuron also fires.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. An impulse travels along a synaptic link between the two neuron. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
For communication within the nervous systems, neurotransmitters are essential. They are also responsible for coordinating activity between various parts of the brain.
What is the most secretive town in the world?
It may surprise you to hear the answer. It may even make it uncomfortable, as it challenges our perceptions of reality and our lives. There is a reason this place exists and it's not as you might expect.
It was called the City of God by ancient Greeks. In the Bible, it was known as the City of Destruction.
It's also known as Kashi (Kashmir) in India. It is called Novgorod (Russia).
But here in America, it goes by another name - The Town That Disappeared.
One tiny town in western New York State lost its 1,200 inhabitants without trace. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
The little village vanished, with no trace of its existence. Some say the earth swallowed it up. Others believe it was destroyed by a meteorite. Others believe that aliens took it.
The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They had just moved to another town.
You can even track the disappearance of Zugspitz on a dedicated website.
So, where exactly did this town go? It's in Switzerland.
The border of Austria and Germany is at Zugspitze. Lake Zugspitze lies just above the summit of the mountain.
It's always fascinated me how so many towns disappear, yet others remain. Why do some disappear while others survive? I decided to investigate.
I was curious about the disappearing towns. What causes a community to disappear? How can a town disappear from existence?
There are several theories behind the disappearing of towns. One theory holds that a town disappears if all its buildings are demolished. Another theory says that the town just moves. Another theory suggests that the town has never existed.
No matter what theories you may have, there is no doubt that many towns across the globe were swallowed by the ground. This video looks into the history of those places and investigates their current status.
Five interesting facts about your liver.
The liver is responsible to detoxify toxins and store vitamins and minerals. It also helps regulate blood pressure and keeps our body temperature stable.
Is it not often that we hear people say "I feel sluggish today" and "my head feels heavier?" These symptoms may be a sign of liver disease.
Some common signs include dark urine, yellowing skin, fatigue, nausea, vomiting, loss of appetite, stomach cramps, jaundice (yellow coloration), and itching. These are not all the warning signs. If you experience any of them, make an appointment with your doctor immediately.
The liver plays a crucial role in our lives. It is vital for detoxification, metabolism, immunity, reproduction, and digestion.
-
The average adult human liver weighs approximately 1,400 grams.
-
The liver of a baby is roughly half the size that of an adult at birth. It grows to be about four times bigger by age three than an infant's.
-
The liver is located just below the rib cage on the left side of the abdomen.
-
The liver has 16 main lobes, with many smaller lobules within the lobes.
-
The liver contains about 10 million individual red blood cells.
