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 often used for the President when they are aboard the aircraft. They often land at an Airbase within an hour from the President's place. If the crisis is very serious, the aircraft will drop off President Obama at a ground command point.
The Gulfstream is a large aircraft, but it isn't the biggest. It is also not one of the most expensive. The plane must still be able to evacuate its crew safely in the event of an emergency. Showers, anti-missile systems, and satellite communications systems are all required. Security requirements include self-defense electronics as well as a jamming device.
In case of conflict, the US air force would like large aircraft produced in America. These include C-5s, C-20Cs, and the C-32A. In the beginning, only two aircraft of this type were anticipated to be purchased. A study done in August 1993 found that the USAF could exercise its option to purchase half of the available 120 aircraft.
Initial concerns were raised by the air force that a commercial airline might not be able carry the president. However, the aircraft were eventually given to the Air Force Reserve and the Air National Guard. Since then, a number of these aircraft have been transferred to the Air Force System Command and the US Forest Service. Many of these aircraft are now presidential transports.
The aircraft were known until recently as C-20Cs. The aircraft were known as C-20Cs until recently. The aircraft was transferred to AMARC at Boeing Cecil Field in Jacksonville, FL on April 29, 2010. After the transfer, the aircraft received a new registration as QF-16C drone.
An antenna extends up to eight kilometers from the aircraft. The antenna can be used in communication with submarines. A few aircraft also have high-frequency radio communication antennas. Communication gear includes 85 telephones, 55 antennas and a jamming device to protect the aircraft against antiaircraft missiles.
Before the Gulfstream III, the aircraft was known simply as the C-17. Named after the legendary C-17 Globemaster II aircraft, it was designed and flown by the United States Army Air Forces. In 1949, the first flight of this aircraft was made. The C-17 was finally named Spirit of Charleston.
The aircraft has a pressurized main cabin with nearly 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. While flying, the ramp can be lowered for parachute drops. Many of the aircraft are made out of aluminum alloy. Composites are used in the landing gear sponsons, control surface, landing-gear door and winglets.
FAQ
What is the most secretive town in the world?
It may surprise you to hear the answer. It might even make you uncomfortable because it challenges our perception of reality and how we live. But there is an explanation for why this place exists, and it's not what you would expect.
The ancient Greeks called it the City of God. It was also known as the City of Destruction according to the Bible.
In India, it's called Kashi (Kashmir). It is also called Novgorod in Russia.
It's called The Town That Has Disappeared here in America.
One small community in western New York State with 1,200 residents vanished without a 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 claim the earth swallowed it. Others believe it was destroyed by a meteorite. Others claim it was taken away by aliens.
The people of this once-thriving community, however, are positive that the town won't disappear forever. They had just moved to a new town.
You can even track the disappearance of Zugspitz on a dedicated website.
Then, where is it? Well, it's in Switzerland!
Zugspitze lies on the border between Austria and Germany. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated me that so many towns have disappeared, yet some still remain. Why does some vanish while others remain? I decided to investigate.
I wanted more information about the mysterious disappearing of towns. What makes a town disappear? How does one place go extinct?
It turned out that there are many theories about disappearing towns. One theory is that a city disappears after all buildings have been demolished. Another theory states that the town simply moves to another location. A third theory states that the town didn't exist at all.
The fact is that hundreds of towns all over the world have been swept away by the ground, despite theories to the contrary. This video examines the past and present status of these areas.
What is the most mysterious place on earth?
Antarctica is the world's most mysterious place on Earth.
We find this place so fascinating. Because it is unlike any other spot on Earth.
It is isolated, remote, and very hard to visit. It is not what you see.
You'll also find the strangest species of wildlife in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some believe it refers to "land of ice". Others believe it comes 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 of the twins was born in winter. Hence, the word antarctic.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. It is too cold for trees, plants and animals.
Yet, life is abundant in this frozen wilderness.
It houses approximately 90% of all Earth's living organisms. There are about 50% of the world's animal, plant and plant species.
What makes Antarctica so special? Here, water freezes into ice instead of evaporating into the air.
This creates large masses of ice that float above the ground.
These floating glaciers cover over 80%. They're getting bigger every year.
The Antarctic ice has grown 60 feet so far since 1960.
The sea level could rise to 200 feet if the melting continues. This could lead worldwide flooding.
But not everyone thinks this is bad news. Some scientists suggest that global warming could actually 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 warn that this theory sounds like something out of a science-fiction movie.
How does your brain control your body's functions?
The brain communicates with other organs to ensure their cooperation. Everything in your body is controlled and managed by your brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Neurons communicate with each other by sending electrical signals called action potentials on axons. 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. Ion movement creates the electric charge that causes the neuron to fire.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. This causes the second neuron to fire too.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. 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.
The nervous system relies on neurotransmitters for communication. They coordinate activity between the different parts of your brain.
What is the most interesting fact about the human body?
Two eyes, two ears, 2 nostrils, 4 limbs, 1 nose, 1 penis and one mouth are all there. It's true, we have more 50 parts of our body, but there is one thing missing. A heart.
The heart is a pump that circulates blood throughout your body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.
Each minute, the heart pumps 5 liters of blood. This is equivalent to a person drinking 2-3 cups coffee daily.
Blood flows through the heart 24 hours a day, 365 days a year. While you sleep, your heart beats almost 100 times per minute.
Skin color can be used to determine if someone has a medical condition. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These small vessels carry blood away from the large blood vessels in the skin back to the heart. The skin turns blue or violet when blood flow becomes blocked.
People suffering from sickle cell disease have no red blood cells. Their blood becomes very sticky and hardened, leading to serious illness.
You can use a bandage to stop bleeding if your cut is severe. For wounds to heal properly, blood must flow. To do this, doctors will insert a needle through your skin into the vein adjacent to the injury. This allows blood flow to the area that has been injured.
Doctors may also insert catheters (catheters), in an artery to treat a blood clot. This keeps the patient occupied until the clot is broken down naturally.
