>> The National Aeronautics and Space Administration (NASA)

The National Aeronautics and Space Administration (NASA) is the agency of the United States Federal Government responsible for the civilian space program as well as aeronautics and aerospace research.

President Dwight D. Eisenhower established NASA in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.

The International Space Station

Since that time, most US space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.

NASA science is focused on better understanding Earth through the Earth Observing System, advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program, exploring bodies throughout the Solar System with advanced robotic spacecraft missions such as New Horizons, and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs NASA shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite.

>> Sukhoi Company is a major Russian aircraft manufacturer

Sukhoi Company (JSC; Russian: ОАО "Компания "Сухой") is a major Russian aircraft manufacturer, headquartered in Begovoy District, Northern Administrative Okrug, Moscow, and designs both civilian and military aircraft. It was founded by Pavel Sukhoi in 1939 as the Sukhoi Design Bureau (OKB-51, design office prefix Su).

After the collapse of the Soviet Union, each of the multitude of bureaus and factories producing Sukhoi components was privatized independently. In 1996, the government re-gathered the major part of them forming Sukhoi Aviation Military Industrial Combine (Sukhoi AIMC). In parallel, other entities, including Ulan Ude factory, Tbilisi factory, Belarus and Ukraine factories, established alternate transnational Sukhoi Attack Aircraft (producing e.g. Su-25 TM).

The Sukhoi AIMC comprises the JSC Sukhoi Design Bureau located in Moscow, the Novosibirsk Aviation Production Association (NAPO), the Komsomolsk-on-Amur Aircraft Production Association (KnAAPO) and Irkutsk Aviation. Sukhoi is headquartered in Moscow. Finmeccanica owns 25% + 1 share of Sukhoi's civil division. The Russian government merged Sukhoi with Mikoyan, Ilyushin, Irkut, Tupolev, and Yakovlev as a new company named United Aircraft Corporation. Mikoyan and Sukhoi were placed within the same operating unit.

Sukhoi is also working on what is to be Russia's fifth-generation stealth fighter, the Sukhoi PAK FA. The maiden flight took place on the 29 January 2010.

ukhoi's Su-24, Su-25, Su-27, Su-30, Su-34, Su-35 and shipborne Su-33 aircraft are in service with the Russian Air Force and Navy as well as foreign armies. The Su-25 is the oldest Sukhoi still in production. Sukhoi attack and fighter aircraft have been supplied to Armenia, India, China, Poland, the Czech Republic, Iraq, Slovakia, Hungary, Georgia, East Germany, Syria, North Korea, Vietnam, Malaysia, Afghanistan, Yemen, Egypt, Libya, Iran, Angola, Ethiopia, Peru, Eritrea, and Indonesia. Venezuela signed contracts for the purchase of 30 Su-30 fighter jets in July 2006. More than 2,000 Sukhoi aircraft were supplied to foreign countries on export contracts. With its Su-26, Su-29 and Su-31 models Sukhoi is also a manufacturer of aerobatic aircraft.

>> The Boeing Company in 2000 - 2009

In January 2000, Boeing chose to expand its presence in another aerospace field of satellite communications by purchasing Hughes Electronics. Hughes Space and Communications Company, which had pioneered the satellite communications field and represented 70 percent of all commercial communications built in 1997.

In September 2001, Boeing moved its corporate headquarters from Seattle to Chicago. Chicago, Dallas and Denver – vying to become the new home of the world's largest aerospace concern – all had offered packages of multimillion-dollar tax breaks. Its offices are located in the Fulton River District, Chicago just outside the Loop, Chicago.

Boeing Everett Factory

On October 10, 2001, Boeing lost to its rival Lockheed Martin in the fierce competition for the multibillion-dollar Joint Strike Fighter contract. Boeing's entry, the X-32, was rejected in favor of Lockheed's X-35 entrant. Boeing continues to serve as the prime contractor on the International Space Station and has built several of the major components. Boeing began development of the KC-767 aerial refueling tanker in the early 2000s. Italy and Japan ordered four KC-767s each. After development delays and FAA certification, Boeing delivered the tankers to Japan from 2008 with the second KC-767 following on 5 March. to 2010. Italy received its four KC-767 during 2011.

In 2004, Boeing ended production of the 757 after 1,050 aircraft were produced. More advanced, stretched versions of the 737 were beginning to compete against the 757, and the planned 787-3 was to fill much of the top end of the 757 market. Also that year, Boeing announced that the 717, the last civil aircraft to be designed by McDonnell Douglas, would cease production in 2006. The 767 was in danger of cancellation as well, with the 787 replacing it, but orders for the freighter version extended the program.

International Space Station

After several decades of success, Boeing lost ground to Airbus and subsequently lost its lead in the airliner market in 2003. Multiple Boeing projects were pursued and then canceled, notably the Sonic Cruiser, a proposed jetliner that would travel just under the speed of sound, cutting intercontinental travel times by as much as 20 percent. It was launched in 2001 along with a new advertising campaign to promote the company's new motto, "Forever New Frontiers", and to rehabilitate its image. However, the plane's fate was sealed by the changes in the commercial aviation market following the September 11 attacks and the subsequent weak economy and increase in fuel prices.

Subsequently, Boeing streamlined its production and turned its attention to a new model, the Boeing 787 Dreamliner, using much of the technology developed for the Sonic Cruiser, but in a more conventional aircraft designed for maximum efficiency. The company also launched new variants of its successful 737 and 777 models. The 787 proved to be highly popular choice with airlines, and won a record number of pre-launch orders. With delays to Airbus' A380 program several airlines threatened to switch their A380 orders to Boeing's new 747 version, the 747-8.[ Airbus's response to the 787, the A350, received a lukewarm response at first when it was announced as an improved version of the A330, and then gained significant orders when Airbus promised an entirely new design. The 787 program has encountered delays, with the first flight not occurring until late 2009.

After regulatory approval, Boeing formed a joint venture, United Launch Alliance with its competitor, Lockheed Martin, on December 1, 2006. The new venture is the largest provider of rocket launch services to the U.S. government.

The Boeing 787 Dreamliner on its first flight

On August 2, 2005, Boeing sold its Rocketdyne rocket engine division to Pratt & Whitney. On May 1, 2006, Boeing agreed to purchase Dallas, Texas-based Aviall, Inc. for $1.7 billion and retain $350 million in debt. Aviall, Inc. and its subsidiaries, Aviall Services, Inc. and ILS formed a wholly owned subsidiary of Boeing Commercial Aviation Services (BCAS).

Realizing that increasing numbers of passengers have become reliant on their computers to stay in touch, Boeing introduced Connexion by Boeing, a satellite based Internet connectivity service that promised air travelers unprecedented access to the World Wide Web. The company debuted the product to journalists in 2005, receiving generally favorable reviews. However, facing competition from cheaper options, such as cellular networks, it proved too difficult to sell to most airlines. In August 2006, after a short and unsuccessful search for a buyer for the business, Boeing chose to discontinue the service.

On August 18, 2007, NASA selected Boeing as the manufacturing contractor for the liquid-fueled upper stage of the Ares I rocket. The stage, based on both Apollo-Saturn and Space Shuttle technologies, was to be constructed at NASA's Michoud Assembly Facility near New Orleans; Boeing constructed the S-IC stage of the Saturn V rocket at this site in the 1960s.

Boeing launched the 777 Freighter in May 2005 with an order from Air France. The freighter variant is based on the −200LR. Other customers include FedEx and Emirates. Boeing officially announced in November 2005 that it would produce a larger variant of the 747, the 747-8, in two versions, commencing with the Freighter version with firm orders for two cargo carriers. The second version, named the Intercontinental, is for passenger airlines. Both 747-8 versions feature a lengthened fuselage, new, advanced engines and wings, and the incorporation of other technologies developed for the 787.

Boeing also received the launch contract from the U.S. Navy for the P-8 Poseidon Multimission Maritime Aircraft, an anti-submarine warfare patrol aircraft. It has also received orders for the 737 AEW&C "Wedgetail" aircraft. The company has also introduced new extended range versions of the 737. These include the 737-700ER and 737-900ER. The 737-900ER is the latest and will extend the range of the 737–900 to a similar range as the successful 737–800 with the capability to fly more passengers, due to the addition of two extra emergency exits.

The record-breaking 777-200LR Worldliner, presented at the Paris Air Show 2005.

The 777-200LR Worldliner embarked on a well-received global demonstration tour in the second half of 2005, showing off its capacity to fly farther than any other commercial aircraft. On November 10, 2005, the 777-200LR set a world record for the longest non-stop flight. The plane, which departed from Hong Kong traveling to London, took a longer route, which included flying over the U.S. It flew 11,664 nautical miles (21,601 km) during its 22-hour 42-minute flight. It was flown by Pakistan International Airlines pilots and PIA was the first airline to fly the 777-200LR Worldliner.

On August 11, 2006, Boeing agreed to form a joint-venture with the large Russian titanium producer, VSMPO-Avisma for the machining of titanium forgings. The forgings will be used on the 787 program. On December 27, 2007 Boeing and VSMPO-Avisma created a joint venture, Ural Boeing Manufacturing, and signed a contract on titanium product deliveries until 2015, with Boeing planning to invest $27 billion in Russia over the next 30 years.

In February 2011, Boeing received a contract for 179 KC-46 U.S. Air Force tankers at a value of $35 billion. The KC-46 tankers are based on the KC-767.

Boeing jointly with Science Applications International Corporation (SAIC), were the prime contractors in the U.S. military's Future Combat Systems program. The FCS program was canceled in June 2009 with all remaining systems swept into the BCT Modernization program. Boeing works jointly with SAIC in the BCT Modernization program like the FCS program but the U.S. Army will play a greater role in creating baseline vehicles and will only contract others for accessories.

Defense Secretary Robert M. Gates' shift in defense spending to, "make tough choices about specific systems and defense priorities based solely on the national interest and then stick to those decisions over time" hit Boeing especially hard, because of their heavy involvement with canceled Air Force projects.

>> Boeing is among the largest global aircraft manufacturers, History before 1930

The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets and satellites. It also provides leasing and product support services. Boeing is among the largest global aircraft manufacturers, is the second-largest defense contractor in the world based on 2013 revenue, and is the largest exporter in the United States by dollar value. Boeing stock is a component of the Dow Jones Industrial Average.

The Boeing Company's corporate headquarters are located in Chicago and the company is led by President and CEO Dennis Muilenburg. Boeing is organized into five primary divisions: Boeing Commercial Airplanes (BCA); Boeing Defense, Space & Security (BDS); Engineering, Operations & Technology; Boeing Capital; and Boeing Shared Services Group. In 2014, Boeing recorded $90.78 billion in sales, ranked 27th on the Fortune magazine "Fortune 500" list (2015), ranked 90th on the "Fortune Global 500" list (2015), and ranked 27th on the "World's Most Admired Companies" list (2015).

Replica of Boeing's first plane, the Boeing Model 1, at the Museum of Flight

In March 1910, William E. Boeing bought Heath's shipyard in Seattle on the Duwamish River, which later became his first airplane factory. Boeing was incorporated in Seattle by William Boeing, on July 15, 1916, as "Pacific Aero Products Co". Boeing was later incorporated in Delaware, the original Certificate of Incorporation was filed with the Secretary of State of Delaware on July 19, 1934. Boeing, who studied at Yale University, worked initially in the timber industry, where he became wealthy and learned about wooden structures. This knowledge proved invaluable in his subsequent design and assembly of airplanes. The company stayed in Seattle to take advantage of the local supply of spruce wood.

William Boeing founded his company a few months after the June 15 maiden flight of one of the two "B&W" seaplanes built with the assistance of George Conrad Westervelt, a U.S. Navy engineer. Boeing and Westervelt decided to build the B&W seaplane after having flown in a Curtiss aircraft. Boeing bought a Glenn Martin "Flying Birdcage" seaplane (so called because of all the guy-wires holding it together) and was taught to fly by Glenn Martin himself. Boeing soon crashed the Birdcage and when Martin informed Boeing that replacement parts would not become available for months, Boeing realized he could build his own plane in that amount of time. He and his friend Cdr. G.C. Westervelt agreed to build a better airplane and soon produced the B&W Seaplane. This first Boeing airplane was assembled in a lakeside hangar located on the northeast shore of Seattle's Lake Union. Many of Boeing's early planes were seaplanes.

On May 9, 1917, the company became the "Boeing Airplane Company". In late 1917, the U.S. entered World War I and Boeing knew that the U.S. Navy needed seaplanes for training. So Boeing shipped two new Model Cs to Pensacola, Florida where the planes were flown for the Navy. The Navy liked the Model C and ordered fifty more.  The company moved its operations to a larger former shipbuilding facility known as Boeing Plant 1, located on the lower Duwamish River.

When World War I ended in 1918, a large surplus of cheap, used military planes flooded the commercial airplane market, and this prevented aircraft companies like Boeing from selling any new airplanes. Because of this, many airplane companies went out of business, but other companies, including Boeing, started selling other products. Boeing built dressers, counters, and furniture, along with flat-bottom boats called Sea Sleds.

William E. Boeing in 1929

In 1919 the Boeing B-1 made its first flight. It was a flying boat that accommodated one pilot and two passengers and some mail. Over the course of eight years, it made international airmail flights from Seattle to Victoria, British Columbia. On May 24, 1920, the Boeing Model 8 made its first flight. It was the first plane to fly over Mount Rainier.

In 1923, Boeing began a competition against Curtiss for a contract to develop a pursuit fighter for the U.S. Army Air Service. Although Curtiss finished its design first and was awarded the contract, Boeing continued to develop its PW-9 fighter. That plane, along with the Boeing P-12/ F4B fighter, made Boeing a leading manufacturer of fighters over the course of the next decade.

In 1925, Boeing built its Model 40 mail plane for the U.S. government to use on airmail routes. In 1927, an improved version of this plane was built, the Model 40A which won the U.S. Post Office's contract to deliver mail between San Francisco and Chicago. The 40A also had a passenger cabin that accommodated two passengers.

That same year, Boeing created an airline named Boeing Air Transport, which merged a year later with Pacific Air Transport and the Boeing Airplane Company. The first airmail flight for the airline was on July 1, 1927.  The company changed its name to United Aircraft and Transport Corporation in 1929 and acquired Pratt & Whitney, Hamilton Standard Propeller Company, and Chance Vought. United Aircraft then purchased National Air Transport in 1930.

On July 27, 1928, the 12-passenger Boeing 80 biplane made its first flight. With three engines, it was Boeing's first plane built with the sole intention of being a passenger transport. An upgraded version, the 80A, carrying eighteen passengers, made its first flight in September 1929.

>> Airbus SAS is a division of the multinational Airbus Group SE that manufactures civil aircraft

Airbus SAS is a division of the multinational Airbus Group SE that manufactures civil aircraft. It is based in Blagnac, France, a suburb of Toulouse, with production and manufacturing facilities mainly in France, Germany, Spain, China, United Kingdom and the United States. The company employs 73,958.

Airbus began as a consortium of aerospace manufacturers, Airbus Industrie. Consolidation of European defence and aerospace companies in 1999 and 2000 allowed the establishment of a simplified joint-stock company in 2001, owned by the European Aeronautic Defence and Space Company (EADS) (80%) and BAE Systems (20%). After a protracted sales process BAE sold its shareholding to EADS on 13 October 2006.

Airbus A300, the first aircraft launched by Airbus

Airbus employs around 63,000 people at sixteen sites in four countries: France, Germany, Spain and the United Kingdom. Final assembly production is based at Toulouse, France; Hamburg, Germany; Seville, Spain; and, since 2009 as a joint-venture, Tianjin, China. Airbus has subsidiaries in the United States, Japan and India.

The company produces and markets the first commercially viable digital fly-by-wire airliner, the Airbus A320, and the world's largest passenger airliner, the A380. Airbus Industrie began as a consortium of European aviation firms to compete with American companies such as Boeing, McDonnell Douglas, and Lockheed.

While many European aircraft were innovative, even the most successful had small production runs. In 1991, Jean Pierson, then CEO and Managing Director of Airbus Industrie, described a number of factors which explained the dominant position of American aircraft manufacturers: the land mass of the United States made air transport the favoured mode of travel; a 1942 Anglo-American agreement entrusted transport aircraft production to the US; and World War II had left America with "a profitable, vigorous, powerful and structured aeronautical industry."

In the mid-1960s, tentative negotiations commenced regarding a European collaborative approach. Individual aircraft companies had already envisaged such a requirement; in 1959 Hawker Siddeley had advertised an "Airbus" version of the Armstrong Whitworth AW.660 Argosy, which would "be able to lift as many as 126 passengers on ultra short routes at a direct operating cost of 2d. per seat mile." However, European aircraft manufacturers were aware of the risks of such a development and began to accept, along with their governments, that collaboration was required to develop such an aircraft and to compete with the more powerful US manufacturers. At the 1965 Paris Air Show major European airlines informally discussed their requirements for a new "airbus" capable of transporting 100 or more passengers over short to medium distances at a low cost.

Eastern Air Lines was Airbus's first customer in the American market, ordering the Airbus A300 B4

The same year Hawker Siddeley (at the urging of the UK government) teamed with Breguet and Nord to study airbus designs. The Hawker Siddeley/Breguet/Nord group's HBN 100 became the basis for the continuation of the project. By 1966 the partners were Sud Aviation, later Aérospatiale (France), Arbeitsgemeinschaft Airbus, later Deutsche Airbus (Germany) and Hawker Siddeley (UK).[10] A request for funding was made to the three governments in October 1966. On 25 July 1967 the three governments agreed to proceed with the proposal.

In the two years following this agreement, both the British and French governments expressed doubts about the project. The MoU had stated that 75 orders must be achieved by 31 July 1968. The French government threatened to withdraw from the project due to the concern over funding development of the Airbus A300, Concorde and the Dassault Mercure concurrently, but was persuaded otherwise. With concerns at proposal of the A300B proposal in December 1968, and fearing it would not recoup its investment due to lack of sales, the British government withdrew on 10 April 1969. Germany took this opportunity to increase its share of the project to 50%. Given the participation by Hawker Siddeley up to that point, France and Germany were reluctant to take over its wing design. Thus the British company was allowed to continue as a privileged subcontractor. Hawker Siddeley invested GB£35 million in tooling and, requiring more capital, received a GB£35 million loan from the German government.

>> History of Taliban

The Taliban movement traces its origin to the Pakistani-trained mujahideen in northern Pakistan, during the Soviet–Afghan War. When Muhammad Zia-ul-Haq became President of Pakistan he feared that the Soviets were planning to invade Balochistan, Pakistan so he sent Akhtar Abdur Rahman to Saudi Arabia to garner support for the Afghan resistance against Soviet occupation forces. In the meantime, the United States and Saudi Arabia joined the struggle against the Soviet Union by providing all the funds. Zia-ul-Haq aligned himself with Pakistan's Jamiat Ulema-e-Islam and later picked General Akhtar Abdur Rahman to lead the insurgency against the Soviet Union inside Afghanistan. About 90,000 Afghans, including Mohammed Omar, were trained by Pakistan's ISI during the 1980s.

President Ronald Reagan meeting with Afghan Mujahideen leaders in the Oval Office in 1983

In his interview with ABC News, the ex Pakistani prime minister and Chief of Army Pervez Musharraf said that western countries, chiefly the USA and United Kingdom, had given aid of about 20 billion dollars during the 1980s to Pakistan specifically for training Taliban personnel and providing them with arms and ammunition.

Due to the sudden initiation of the civil war, working government departments, police units or a system of justice and accountability for the newly created Islamic State of Afghanistan did not have time to form. Horrific crimes were committed by criminals and individuals inside different factions. Rare ceasefires, usually negotiated by representatives of the Islamic State's newly appointed Defense Minister Ahmad Shah Massoud, President Sibghatullah Mojaddedi and later President Burhanuddin Rabbani (the interim government), or officials from the International Committee of the Red Cross (ICRC), commonly collapsed within days. The countryside in northern Afghanistan, parts of which was under the control of Defense Minister Massoud remained calm and some reconstruction took place. The city of Herat under the rule of Islamic State ally Ismail Khan also witnessed relative calm.

Meanwhile, southern Afghanistan was neither under the control of foreign-backed militias nor the government in Kabul, but was ruled by local leaders such as Gul Agha Sherzai and their militias.

The Taliban were removed from power in October 2001 by a unified effort of United Islamic Front (Northern Alliance) ground forces, small U.S. Special Operations teams and U.S. air support.

In 1991, the Taliban (a movement originating from Jamiat Ulema-e-Islam-run religious schools for Afghan refugees in Pakistan) also developed in Afghanistan as a politico-religious force. The most often-repeated story and the Taliban's own story of how Mullah Omar first mobilized his followers is that in the spring of 1994, neighbors in Singesar told him that the local governor had abducted two teenage girls, shaved their heads, and taken them to a camp where they were raped. 30 Taliban (with only 16 rifles) freed the girls, and hanged the governor from the barrel of a tank. Later that year, two militia commanders killed civilians while fighting for the right to sodomize a young boy. The Taliban freed him. Mullah Omar started his movement with fewer than 50 armed madrassah students in his hometown of Kandahar.

In the beginning the Taliban numbered in the hundreds, were badly equipped and low on munitions. Within months however 15,000 students arrived from the madrassas in Pakistan. The Taliban's first major military activity was in 1994, when they marched northward from Maiwand and captured Kandahar City and the surrounding provinces, losing only a few dozen men. When they took control of Kandahar in 1994, they forced the surrender of dozens of local Pashtun leaders who had presided over a situation of complete lawlessness and atrocities. The Taliban also took over a border crossing at Spin Baldak and an ammunition dump from Gulbuddin Hekmatyar. In the course of 1994, the Taliban took control of 12 of 34 provinces not under central government control. Militias controlling the different areas often surrendered without a fight. Omar's original commanders were "a mixture of former small-unit military commanders and madrassa teachers."

At the same time most of the militia factions (Hekmatyar's Hezb-i Islami, Dostum's Junbish-i Milli and Hezb-i Wahdat) fighting in the battle for control of Kabul were defeated militarily by forces of the Islamic State's Defense Minister Ahmad Shah Massoud. Bombardment of the capital came to a halt and the Islamic State initiated measures to restore law and order to the capital. Massoud furthermore tried to initiate a nationwide political process with the goal of national consolidation and democratic elections.

Afghan Taliban fighters overran an Afghan military base and paraded its troops through the bazaar in Kajaki in northern Helmand province.

Ahmad Shah Massoud, known as the "Lion of Panjshir", had been named "the Afghan who won the Cold War" by the Wall Street Journal and had defeated the Soviet Red Army nine times in north-eastern Afghanistan. Hoping for the Taliban to be allies in bringing stability to Afghanistan, Massoud invited the Taliban to join the consolidation process and to contribute to stability. Unarmed, Massoud went to talk to Taliban leaders in Maidan Shar to convince them to join the initiated political process, so that democratic elections could be held to decide on a future government for Afghanistan. The Taliban declined to join such a political process. When Massoud returned unharmed to Kabul, the Taliban leader who had received him as his guest was killed by other senior Taliban for failing to execute Massoud while the possibility had presented itself.

The Taliban, however, suffered a devastating defeat against government forces of the Islamic State under the command of Ahmad Shah Massoud. The Taliban's early victories in 1994 were followed by a series of defeats that resulted in heavy losses which led analysts to believe that the Taliban movement as such might have run its course. Pakistan, however, started to provide stronger military support to the Taliban. On September 26, 1996, as the Taliban with military support by Pakistan and financial support by Saudi Arabia prepared for another major offensive, Massoud ordered a full retreat from Kabul to continue anti-Taliban resistance in the Hindu Kush mountains instead of engaging in street battles in Kabul. The Taliban entered Kabul on September 27, 1996, and established the Islamic Emirate of Afghanistan. Many analysts like Amin Saikal describe the Taliban as developing into a proxy force for Pakistan's regional interests.

>> The Taliban is an Islamic fundamentalist political movement in Afghanistan

The Taliban is an Islamic fundamentalist political movement in Afghanistan currently waging war (an insurgency, or jihad) within that country. From 1996 to 2001, it held power in Afghanistan and enforced a strict interpretation of Sharia, or Islamic law, of which the international community and leading Muslims have been highly critical. Until his death in 2013, Mullah Mohammed Omar was the supreme commander and spiritual leader of the Taliban. Mullah Akhtar Mansour was elected as his replacement in 2015, but as of November 2015 there are conflicting reports that he may have been killed or badly wounded. As of mid-2015, the group is "directly or indirectly" supported in Afghanistan by "about a dozen" militant groups, having "different goals and agendas".

President Ronald Reagan meeting with Afghan Mujahideen leaders in the Oval Office in 1983

The movement originated in the early 1990s, but was not fully unified until its 1994 capture of Kandahar. Under the leadership of Mohammed Omar, the movement spread throughout most of Afghanistan, sequestering power from the Mujahideen warlords, whose corruption and despotism Afghans had tired of. The Islamic Emirate of Afghanistan was established in 1996 and the Afghan capital transferred to Kandahar. It held control of most of the country until being overthrown by the American-led invasion of Afghanistan in December 2001 following the September 11 attacks. At its peak, formal diplomatic recognition of the Taliban's government was acknowledged by only three nations: Pakistan, Saudi Arabia, and the United Arab Emirates. The group later regrouped as an insurgency movement to fight the American-backed Karzai administration and the NATO-led International Security Assistance Force (ISAF).

The Taliban have been condemned internationally for the harsh enforcement of their interpretation of Islamic Sharia law, which has resulted in the brutal treatment of many Afghans, especially women. During their rule from 1996 to 2001, the Taliban and their allies committed massacres against Afghan civilians, denied UN food supplies to 160,000 starving civilians and conducted a policy of scorched earth, burning vast areas of fertile land and destroying tens of thousands of homes. In its post-9/11 insurgency, the group has been accused of using terrorism as a specific tactic to further their ideological and political goals. According to the United Nations, the Taliban and their allies were responsible for 75% of Afghan civilian casualties in 2010, 80% in 2011, and 80% in 2012.

The Taliban emerged in the southern Afghan city of Kandahar around September 1994.

The Taliban's ideology has been described as anti-modern, combining an "innovative form" of sharia Islamic law based on Deobandi fundamentalism and the militant Islamism and Salafi jihadism of Osama bin Laden, with Pashtun social and cultural norms known as Pashtunwali, as most Taliban are Pashtun tribesmen.

The Pakistani Inter-Services Intelligence and military are widely alleged by the international community to have provided support to the Taliban during their founding and time in power, and of continuing to support the Taliban during the insurgency. Pakistan states that it dropped all support for the group after the September 11 attacks. Al-Qaeda also supported the Taliban with fighters from Arab countries and Central Asia. Saudi Arabia provided financial support. Hundreds of thousands of people were forced to flee to United Front-controlled territory, Pakistan, and Iran.

>> Hotak dynasty and Durrani Empire of Afghanistan

In 1709, Mirwais Hotak, a local Ghilzai tribal leader, successfully rebelled against the Safavids. He defeated Gurgin Khan and made Afghanistan independent. Mirwais died of a natural cause in 1715 and was succeeded by his brother Abdul Aziz, who was soon killed by Mirwais' son Mahmud for treason. Mahmud led the Afghan army in 1722 to the Persian capital of Isfahan, captured the city after the Battle of Gulnabad and proclaimed himself King of Persia. The Afghan dynasty was ousted from Persia by Nader Shah after the 1729 Battle of Damghan.

In 1738, Nader Shah and his forces captured Kandahar, the last Hotak stronghold, from Shah Hussain Hotak, at which point the incarcerated 16-year-old Ahmad Shah Durrani was freed and made the commander of an Afghan regiment. Soon after the Persian and Afghan forces invaded India. By 1747, the Afghans chose Durrani as their head of state. Durrani and his Afghan army conquered much of present-day Afghanistan, Pakistan, the Khorasan and Kohistan provinces of Iran, and Delhi in India. He defeated the Indian Maratha Empire, and one of his biggest victories was the 1761 Battle of Panipat.

Ahmad Shah Durrani, founder of the last Afghan empire and viewed as Father of the Nation

In October 1772, Durrani died of a natural cause and was buried at a site now adjacent to the Shrine of the Cloak in Kandahar. He was succeeded by his son, Timur Shah, who transferred the capital of Afghanistan from Kandahar to Kabul in 1776. After Timur's death in 1793, the Durrani throne passed down to his son Zaman Shah, followed by Mahmud Shah, Shuja Shah and others.

The Afghan Empire was under threat in the early 19th century by the Persians in the west and the British-backed Sikhs in the east. Fateh Khan, leader of the Barakzai tribe, had installed 21 of his brothers in positions of power throughout the empire. After his death, they rebelled and divided up the provinces of the empire between themselves. During this turbulent period, Afghanistan had many temporary rulers until Dost Mohammad Khan declared himself emir in 1826. The Punjab region was lost to Ranjit Singh, who invaded Khyber Pakhtunkhwa and in 1834 captured the city of Peshawar. In 1837, during the Battle of Jamrud near the Khyber Pass, Akbar Khan and the Afghan army killed Sikh Commander Hari Singh Nalwa. By this time the British were advancing from the east and the first major conflict during the "Great Game" was initiated.

>> Islamic conquest of Afghanistan and Mongol invasion of Central Asia

Arab Muslims brought Islam to Herat and Zaranj in 642 CE and began spreading eastward; some of the native inhabitants they encountered accepted it while others revolted. The land was collectively recognized by the Arabs as al-Hind due to its cultural connection with Greater India. Before Islam was introduced, people of the region were mostly Buddhists and Zoroastrians, but there were also Surya and Nana worshipers, Jews, and others. The Zunbils and Kabul Shahi were first conquered in 870 CE by the Saffarid Muslims of Zaranj. Later, the Samanids extended their Islamic influence south of the Hindu Kush. It is reported that Muslims and non-Muslims still lived side by side in Kabul before the Ghaznavids rose to power in the 10th century.

By the 11th century, Mahmud of Ghazni defeated the remaining Hindu rulers and effectively Islamized the wider region, with the exception of Kafiristan. Afghanistan became one of the main centers in the Muslim world during this Islamic Golden Age. The Ghaznavid dynasty was overthrown by the Ghurids, who expanded and advanced the already powerful Islamic empire.

In 1219 AD, Genghis Khan and his Mongol army overran the region. His troops are said to have annihilated the Khorasanian cities of Herat and Balkh as well as Bamyan. The destruction caused by the Mongols forced many locals to return to an agrarian rural society. Mongol rule continued with the Ilkhanate in the northwest while the Khilji dynasty administered the Afghan tribal areas south of the Hindu Kush until the invasion of Timur, who established the Timurid Empire in 1370.

In the early 16th century, Babur arrived from Fergana and captured Kabul from the Arghun dynasty. In 1526, he invaded Delhi in India to replace the Lodi dynasty with the Mughal Empire. Between the 16th and 18th century, the Khanate of Bukhara, Safavids, and Mughals ruled parts of the territory. Before the 19th century, the northwestern area of Afghanistan was referred to by the regional name Khorasan. Two of the four capitals of Khorasan (Herat and Balkh) are now located in Afghanistan, while the regions of Kandahar, Zabulistan, Ghazni, Kabulistan, and Afghanistan formed the frontier between Khorasan and Hindustan.

>> Pre-Islamic period of Afghanistan

Archaeological exploration done in the 20th century suggests that the geographical area of Afghanistan has been closely connected by culture and trade with its neighbors to the east, west, and north. Artifacts typical of the Paleolithic, Mesolithic, Neolithic, Bronze, and Iron ages have been found in Afghanistan. Urban civilization is believed to have begun as early as 3000 BCE, and the early city of Mundigak (near Kandahar in the south of the country) may have been a colony of the nearby Indus Valley Civilization. More recent findings established that the Indus Valley Civilisation stretched up towards modern-day Afghanistan, making the ancient civilisation today part of Pakistan, Afghanistan and India. In more detail, it extended from what today is northwest Pakistan to northwest India and northeast Afghanistan. An Indus Valley site has been found on the Oxus River at Shortugai in northern Afghanistan. There are several smaller IVC colonies to be found in Afghanistan as well.

After 2000 BCE, successive waves of semi-nomadic people from Central Asia began moving south into Afghanistan; among them were many Indo-European-speaking Indo-Iranians. These tribes later migrated further into South Asia, Western Asia, and toward Europe via the area north of the Caspian Sea. The region at the time was referred to as Ariana.

The religion Zoroastrianism is believed by some to have originated in what is now Afghanistan between 1800 and 800 BCE, as its founder Zoroaster is thought to have lived and died in Balkh. Ancient Eastern Iranian languages may have been spoken in the region around the time of the rise of Zoroastrianism. By the middle of the 6th century BCE, the Achaemenids overthrew the Medes and incorporated Arachosia, Aria, and Bactria within its eastern boundaries. An inscription on the tombstone of Darius I of Persia mentions the Kabul Valley in a list of the 29 countries that he had conquered.

Alexander the Great and his Macedonian forces arrived to Afghanistan in 330 BCE after defeating Darius III of Persia a year earlier in the Battle of Gaugamela. Following Alexander's brief occupation, the successor state of the Seleucid Empire controlled the region until 305 BCE, when they gave much of it to the Maurya Empire as part of an alliance treaty. The Mauryans controlled the area south of the Hindu Kush until they were overthrown in about 185 BCE. Their decline began 60 years after Ashoka's rule ended, leading to the Hellenistic reconquest by the Greco-Bactrians. Much of it soon broke away from them and became part of the Indo-Greek Kingdom. They were defeated and expelled by the Indo-Scythians in the late 2nd century BCE.

During the first century BCE, the Parthian Empire subjugated the region, but lost it to their Indo-Parthian vassals. In the mid-to-late first century CE the vast Kushan Empire, centered in Afghanistan, became great patrons of Buddhist culture, making Buddhism flourish throughout the region. The Kushans were overthrown by the Sassanids in the 3rd century CE, though the Indo-Sassanids continued to rule at least parts of the region. They were followed by the Kidarite who, in turn, were replaced by the Hephthalites. By the 6th century CE, the successors to the Kushans and Hepthalites established a small dynasty called Kabul Shahi. Much of the northeastern and southern areas of the country remained dominated by Buddhist culture.

>> Afghanistan is a landlocked country located within South Asia and Central Asia

The name Afghānistān is believed to be as old as the ethnonym Afghan, which is documented in the 10th-century geography book Hudud ul-'alam. The root name "Afghan" was used historically in reference to a member of the ethnic Pashtuns, and the suffix "-stan" means "place of" in Sanskrit. Therefore, Afghanistan translates to land of the Afghans or, more specifically in a historical sense, to land of the Pashtuns. However, the modern Constitution of Afghanistan states that "[t]he word Afghan shall apply to every citizen of Afghanistan."

Kabul

Excavations of prehistoric sites by Louis Dupree and others suggest that humans were living in what is now Afghanistan at least 50,000 years ago, and that farming communities in the area were among the earliest in the world. An important site of early historical activities, many believe that Afghanistan compares to Egypt in terms of the historical value of its archaeological sites.

The country sits at a unique nexus point where numerous civilizations have interacted and often fought. It has been home to various peoples through the ages, among them the ancient Iranian peoples who established the dominant role of Indo-Iranian languages in the region. At multiple points, the land has been incorporated within large regional empires, among them the Achaemenid Empire, the Macedonian Empire, the Indian Maurya Empire, and the Islamic Empire.

Many empires and kingdoms have also risen to power in Afghanistan, such as the Greco-Bactrians, Kushans, Hephthalites, Kabul Shahis, Saffarids, Samanids, Ghaznavids, Ghurids, Khiljis, Kartids, Timurids, Mughals, and finally the Hotak and Durrani dynasties that marked the political origins of the modern state.

Afghanistan is a landlocked country located within South Asia and Central Asia. It has a population of approximately 32 million, making it the 42nd most populous country in the world. It is bordered by Pakistan in the south and east; Iran in the west; Turkmenistan, Uzbekistan, and Tajikistan in the north; and China in the far northeast. Its territory covers 652,000 km2 (252,000 sq mi), making it the 41st largest country in the world.

Human habitation in Afghanistan dates back to the Middle Paleolithic Era, and the country's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia. Through the ages the land has been home to various peoples and witnessed numerous military campaigns; notably by Alexander the Great, Muslim Arabs, Mongols, British, Soviet Russians, and in the modern-era by Western powers. The land also served as the source from which the Kushans, Hephthalites, Samanids, Saffarids, Ghaznavids, Ghorids, Khiljis, Mughals, Hotaks, Durranis, and others have risen to form major empires.

The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century. In the late 19th century, Afghanistan became a buffer state in the "Great Game" between British India and the Russian Empire. Following the Third Anglo-Afghan War in 1919, King Amanullah unsuccessfully attempted to modernize the country. It remained peaceful during Zahir Shah's forty years of monarchy. A series of coups in the 1970s was followed by a series of civil wars that devastated much of Afghanistan. This was followed by the recent $100 billion nationwide rebuilding process.

>> Culture of India

Indian cultural history spans more than 4,500 years. During the Vedic period (c. 1700 – 500 BCE), the foundations of Hindu philosophy, mythology, theology and literature were laid, and many beliefs and practices which still exist today, such as dhárma, kárma, yóga, and mokṣa, were established. India is notable for its religious diversity, with Hinduism, Buddhism, Sikhism, Islam, Christianity, and Jainism among the nation's major religions. The predominant religion, Hinduism, has been shaped by various historical schools of thought, including those of the Upanishads, the Yoga Sutras, the Bhakti movement, and by Buddhist philosophy.

Much of Indian architecture, including the Taj Mahal, other works of Mughal architecture, and South Indian architecture, blends ancient local traditions with imported styles. Vernacular architecture is also highly regional in it flavours. Vastu shastra, literally "science of construction" or "architecture" and ascribed to Mamuni Mayan, explores how the laws of nature affect human dwellings; it employs precise geometry and directional alignments to reflect perceived cosmic constructs.

As applied in Hindu temple architecture, it is influenced by the Shilpa Shastras, a series of foundational texts whose basic mythological form is the Vastu-Purusha mandala, a square that embodied the "absolute". The Taj Mahal, built in Agra between 1631 and 1648 by orders of Emperor Shah Jahan in memory of his wife, has been described in the UNESCO World Heritage List as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage". Indo-Saracenic Revival architecture, developed by the British in the late 19th century, drew on Indo-Islamic architecture.

The earliest literary writings in India, composed between 1700 BCE and 1200 CE, were in the Sanskrit language. Prominent works of this Sanskrit literature include epics such as the Mahābhārata and the Ramayana, the dramas of Kālidāsa such as the Abhijñānaśākuntalam (The Recognition of Śakuntalā), and poetry such as the Mahākāvya Kamasutra, the famous book about sexual intercourse also originated in India. Developed between 600 BCE and 300 CE in South India, the Sangam literature, consisting of 2,381 poems, is regarded as a predecessor of Tamil literature.

From the 14th to the 18th centuries, India's literary traditions went through a period of drastic change because of the emergence of devotional poets such as Kabīr, Tulsīdās, and Guru Nānak. This period was characterised by a varied and wide spectrum of thought and expression; as a consequence, medieval Indian literary works differed significantly from classical traditions. In the 19th century, Indian writers took a new interest in social questions and psychological descriptions. In the 20th century, Indian literature was influenced by the works of Bengali poet and novelist Rabindranath Tagore.

Indian music ranges over various traditions and regional styles. Classical music encompasses two genres and their various folk offshoots: the northern Hindustani and southern Carnatic schools. Regionalised popular forms include filmi and folk music; the syncretic tradition of the bauls is a well-known form of the latter. Indian dance also features diverse folk and classical forms. Among the better-known folk dances are the bhangra of Punjab, the bihu of Assam, the chhau of Odisha, West Bengal and Jharkhand, garba and dandiya of Gujarat, ghoomar of Rajasthan, and the lavani of Maharashtra.

Eight dance forms, many with narrative forms and mythological elements, have been accorded classical dance status by India's National Academy of Music, Dance, and Drama. These are: bharatanatyam of the state of Tamil Nadu, kathak of Uttar Pradesh, kathakali and mohiniyattam of Kerala, kuchipudi of Andhra Pradesh, manipuri of Manipur, odissi of Odisha, and the sattriya of Assam. Theatre in India melds music, dance, and improvised or written dialogue. Often based on Hindu mythology, but also borrowing from medieval romances or social and political events, Indian theatre includes the bhavai of Gujarat, the jatra of West Bengal, the nautanki and ramlila of North India, tamasha of Maharashtra, burrakatha of Andhra Pradesh, terukkuttu of Tamil Nadu, and the yakshagana of Karnataka.

>> History of Ancient India

The earliest authenticated human remains in South Asia date to about 30,000 years ago. Nearly contemporaneous Mesolithic rock art sites have been found in many parts of the Indian subcontinent, including at the Bhimbetka rock shelters in Madhya Pradesh. Around 7000 BCE, the first known Neolithic settlements appeared on the subcontinent in Mehrgarh and other sites in western Pakistan. These gradually developed into the Indus Valley Civilisation, the first urban culture in South Asia; it flourished during 2500–1900 BCE in Pakistan and western India. Centred around cities such as Mohenjo-daro, Harappa, Dholavira, and Kalibangan, and relying on varied forms of subsistence, the civilisation engaged robustly in crafts production and wide-ranging trade.

Map of the Indian subcontinent during the Vedic period

During the period 2000–500 BCE, in terms of culture, many regions of the subcontinent transitioned from the Chalcolithic to the Iron Age. The Vedas, the oldest scriptures of Hinduism, were composed during this period, and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain. Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into the subcontinent. The caste system arose during this period, creating a hierarchy of priests, warriors, free peasants and traders, and lastly the indigenous peoples who were regarded as impure; and small tribal units gradually coalesced into monarchical, state-level polities. On the Deccan Plateau, archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation.  In southern India, a progression to sedentary life is indicated by the large number of megalithic monuments dating from this period, as well as by nearby traces of agriculture, irrigation tanks, and craft traditions.

In the late Vedic period, around the 6th century BCE, the small states and chiefdoms of the Ganges Plain and the north-western regions had consolidated into 16 major oligarchies and monarchies that were known as the mahajanapadas. The emerging urbanisation gave rise to non-Vedic religious movements, two of which became independent religions. Jainism came into prominence during the life of its exemplar, Mahavira. Buddhism, based on the teachings of Gautama Buddha attracted followers from all social classes excepting the middle class; chronicling the life of the Buddha was central to the beginnings of recorded history in India. In an age of increasing urban wealth, both religions held up renunciation as an ideal and both established long-lasting monastic traditions.

Politically, by the 3rd century BCE, the kingdom of Magadha had annexed or reduced other states to emerge as the Mauryan Empire. The empire was once thought to have controlled most of the subcontinent excepting the far south, but its core regions are now thought to have been separated by large autonomous areas. The Mauryan kings are known as much for their empire-building and determined management of public life as for Ashoka's renunciation of militarism and far-flung advocacy of the Buddhist dhamma.

The Sangam literature of the Tamil language reveals that, between 200 BCE and 200 CE, the southern peninsula was being ruled by the Cheras, the Cholas, and the Pandyas, dynasties that traded extensively with the Roman Empire and with West and South-East Asia. In North India, Hinduism asserted patriarchal control within the family, leading to increased subordination of women. By the 4th and 5th centuries, the Gupta Empire had created in the greater Ganges Plain a complex system of administration and taxation that became a model for later Indian kingdoms.

Under the Guptas, a renewed Hinduism based on devotion rather than the management of ritual began to assert itself. The renewal was reflected in a flowering of sculpture and architecture, which found patrons among an urban elite. Classical Sanskrit literature flowered as well, and Indian science, astronomy, medicine, and mathematics made significant advances.

>> The Sahara is the world's largest low-latitude hot desert " Temperature and Climate "

The Sahara is the world's largest low-latitude hot desert. The area is located in the horse latitudes under the subtropical ridge, a significant belt of semi-permanent subtropical warm-core high pressure where the air from upper levels of the troposphere tends to sink towards the ground. This steady descending airflow causes a warming and a drying effect in the upper troposphere. The sinking air prevents evaporating water from rising and, therefore, prevents the adiabatic cooling, which makes cloud formation extremely difficult to nearly impossible.

A geographical map of Africa, showing the ecological break that defines the Saharan area.

The permanent dissolution of clouds allows unhindered light and thermal radiation. The stability of the atmosphere above the desert prevents any convective overturning, thus making rainfall virtually non-existent. As a consequence, the weather tends to be sunny, dry and stable with a minimal risk of rainfall. Subsiding, diverging, dry air masses associated with subtropical high-pressure systems are extremely unfavorable for the development of convectional showers. The subtropical ridge is the predominate factor that explains the hot desert climate (Köppen climate classification BWh) of this vast region. The lowering of air is the strongest and the most effective over the eastern part of the Great Desert, in the Libyan Desert which is the sunniest, the driest and the most nearly rainless place on the planet rivaling the Atacama Desert, lying in Chile and Peru.

The rainfall inhibition and the dissipation of cloud cover are most accentuated over the eastern section of the Sahara rather than the western. The prevailing air mass lying above the Sahara is the continental tropical (cT) air mass which is hot and dry. Hot, dry air masses primarily form over the North-African desert from the heating of the vast continental land area, and it affects the whole desert during most of the year. Because of this extreme heating process, a thermal low is usually noticed near the surface, and is the strongest and the most developed during the summertime. The Sahara High represents the eastern continental extension of the Azores High, centered over the North Atlantic Ocean. The subsidence of the Sahara High nearly reaches the ground during the coolest part of the year while it limits to the upper troposphere during the hottest periods.

The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.

An oasis in the Ahaggar Mountains. Oases support some life forms in extremely arid deserts.

Condensation occurs on the windward side producing some cloudiness and rainfall while the leeward side stays sunny and dry due to the evaporation process. The leeward side is obviously the desert. This range prevents the unstable weather systems to penetrate further in the interior and to affect these arid regions. That's why there is a sharp decrease in rainfall between the adjacent Mediterranean climates and the desert climate of the Sahara.

The primary source of rain in the Sahara is the equatorial low a continuous belt of low-pressure systems near the equator which bring the brief, short and irregular rainy season to the Sahel and the southern Sahara. The Sahara doesn't lack precipitation because of a lack of moisture, but due to the lack of a precipitation-generating mechanism. Rainfall in this giant desert has to overcome the physical and atmospheric barriers that normally prevent the production of precipitation. The harsh climate of the Sahara is characterized by extremely low, unreliable, highly erratic rainfall; extremely high sunshine duration values; high temperatures year-round; negligible rates of relative humidity, a significant diurnal temperature variation and extremely high levels of potential evaporation which are the highest recorded worldwide.

The sky is usually clear above the desert and the sunshine duration is extremely high everywhere in the Sahara. Most of the desert enjoys more than 3,600 h of bright sunshine annually or over 82% of the time and a wide area in the eastern part experiences in excess of 4,000 h of bright sunshine a year or over 91% of the time, and the highest values are very close to the theoretical maximum value. A value of 4,300 h or 98% of the time would be recorded in Upper Egypt (Aswan, Luxor) and in the Nubian Desert (Wadi Halfa). The annual average direct solar irradiation is around 2,800 kWh/(m2 year) in the Great Desert. The Sahara has a huge potential for solar energy production. The constantly high position of the sun, the extremely low relative humidity, the lack of vegetation and rainfall make the Great Desert the hottest continuously large area worldwide and certainly the hottest place on Earth during summertime in some spots. The average high temperature exceeds 38 °C (100.4 °F) - 40 °C (104 °F) during the hottest month nearly everywhere in the desert except at very high mountainous areas. The highest officially recorded average high temperature was 47 °C (116.6 °F) in a remote desert town in the Algerian Desert called Bou Bernous with an elevation of 378 meters above sea level.

Rocky mountains naturally sculpted by the wind

It's the world's highest recorded average high temperature and only Death Valley, California rivals it. Other hot spots in Algeria such as Adrar, Timimoun, In Salah, Ouallene, Aoulef, Reggane with an elevation between 200 and 400 meters above sea level get slightly lower summer average highs around 46 °C (114.8 °F) during the hottest months of the year. Salah, well known in Algeria for its extreme heat, has an average high temperature of 43.8 °C (110.8 °F), 46.4 °C (115.5 °F), 45.5 (113.9 °F). Furthermore, 41.9 °C (107.4 °F) in June, July, August and September. In fact, there are even hotter spots in the Sahara, but they are located in extremely remote areas, especially in the Azalai, lying in northern Mali. The major part of the desert experiences around 3 – 5 months when the average high strictly exceeds 40 °C (104 °F). The southern central part of the desert experiences up to 6 – 7 months when the average high temperature strictly exceeds 40 °C (104 °F) which shows the constancy and the length of the really hot season in the Sahara. Some examples of this are Bilma, Niger and Faya-Largeau, Chad. The annual average daily temperature exceeds 20 °C (68 °F) everywhere and can approach 30 °C (86 °F) in the hottest regions year-round. However, most of the desert has a value in excess of 25 °C (77 °F). The sand and ground temperatures are even more extreme.

During daytime, the sand temperature is extremely high as it can easily reach 80 °C (176 °F) or more. A sand temperature of 83.5 °C (182.3 °F) has been recorded in Port Sudan. Ground temperatures of 72 °C (161.6 °F) have been recorded in the Adrar of Mauritania and a value of 75 °C (167 °F) has been measured in Borkou, northern Chad. Due to lack of cloud cover and very low humidity, the desert usually features high diurnal temperature variations between days and nights. However, it's a myth that the nights are cold after extremely hot days in the Sahara. The average diurnal temperature range is typically between 13 °C (55.4 °F) and 20 °C (68 °F). The lowest values are found along the coastal regions due to high humidity and are often even lower than 10 °C (50 °F), while the highest values are found in inland desert areas where the humidity is the lowest, mainly in the southern Sahara. Still, it's true that winter nights can be cold as it can drop to the freezing point and even below, especially in high-elevation areas.

>> The Sahara is the largest hot desert in the world

The Sahara is the largest hot desert in the world, and the world's third largest desert after Antarctica and the Arctic. Its surface area of 9,400,000 square kilometres (3,600,000 sq mi, including the Libyan Desert—is comparable to the respective land areas of China or the United States. The desert comprises much of the land found within North Africa, excluding the fertile coastal region situated against the Mediterranean Sea, the Atlas Mountains of the Maghreb, and the Nile Valley of Egypt and Sudan. The Sahara stretches from the Red Sea in the east and the Mediterranean in the north, to the Atlantic Ocean in the west, where the landscape gradually transitions to a coastal plain. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, and the Libyan Desert. Its name is derived from the plural Arabic language word for desert.

The Sahara covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia, extends over 9 million square kilometres (3,500,000 sq mi) and it covers about 1⁄4 of the African continent. If all areas with a mean annual precipitation of less than 250 mm were included, the Sahara would be over 11 million square kilometres (4,200,000 sq mi) in area. It is one of three distinct physiographic provinces of the African massive physiographic division.

Most of the Sahara consists of rocky hamada; ergs (large areas covered with sand dunes) form only a minor part. Many of its sand dunes reach over 180 metres (590 ft) in height. The desert landforms of the Sahara are shaped by wind or by extremely rare rainfall and include sand dunes and dune fields or sand seas (erg), stone plateaus (hamada), gravel plains (reg), dry valleys (wadi), dry lakes (oued) and salt flats (shatt or chott). Unusual landforms include the Richat Structure in Mauritania.

Several deeply dissected mountains and mountain ranges, many volcanic, rise from the desert, including the Aïr Mountains, Ahaggar Mountains, Saharan Atlas, Tibesti Mountains, Adrar des Iforas, and the Red Sea hills. The highest peak in the Sahara is Emi Koussi, a shield volcano in the Tibesti range of northern Chad.

Most of the rivers and streams in the Sahara are seasonal or intermittent, the chief exception being the Nile River, which crosses the desert from its origins in central Africa to empty into the Mediterranean. Underground aquifers sometimes reach the surface, forming oases, including the Bahariya, Ghardaïa, Timimoun, Kufra, and Siwa.

The central part of the Sahara is hyperarid, with little to no vegetation. The northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs in wadis where moisture collects. In the central, hyperarid part, there are many subdivisions of the great desert such as the Tanezrouft, the Ténéré, the Libyan Desert, the Eastern Desert, the Nubian Desert and others. These absolute desert regions are characterized by their extreme aridity, and some years can pass without any rainfall.

To the north, the Sahara skirts the Mediterranean Sea in Egypt and portions of Libya, but in Cyrenaica and the Maghreb, the Sahara borders the Mediterranean forest, woodland, and scrub ecoregions of northern Africa, all of which have a Mediterranean climate characterized by hot summers and cool and rainy winters. According to the botanical criteria of Frank White and geographer Robert Capot-Rey, the northern limit of the Sahara corresponds to the northern limit of date palm cultivation and the southern limit of the range of esparto, a grass typical of the Mediterranean climate portion of the Maghreb and Iberia. The northern limit also corresponds to the 100 mm (3.9 in) isohyet of annual precipitation.

To the south, the Sahara is bounded by the Sahel, a belt of dry tropical savanna with a summer rainy season that extends across Africa from east to west. The southern limit of the Sahara is indicated botanically by the southern limit of Cornulaca monacantha (a drought-tolerant member of the Chenopodiaceae), or northern limit of Cenchrus biflorus, a grass typical of the Sahel. According to climatic criteria, the southern limit of the Sahara corresponds to the 150 mm (5.9 in) isohyet of annual precipitation (this is a long-term average, since precipitation varies annually).

Important cities located in the Sahara include Nouakchott, the capital of Mauritania; Tamanrasset, Ouargla, Béchar, Hassi Messaoud, Ghardaïa, and El Oued in Algeria; Timbuktu in Mali; Agadez in Niger; Ghat in Libya; and Faya-Largeau in Chad.

Following the 2008 Sichuan earthquake, Chan donated RMB ¥10 million to help those in need. In addition, he is planning to make a film about the Chinese earthquake to raise money for survivors. In response to the 2011 Tōhoku earthquake and tsunami, Chan and fellow Hong Kong-based celebrities, including American rapper MC Jin, headlined a special three-hour charity concert, titled Artistes 311 Love Beyond Borders, on 1 April 2011 to help with Japan's disaster recovery effort. The 3-hour concert raised over $3.3 million.

Chan founded the Jackie Chan Charitable Foundation in 1988, to offers scholarship and active help to Hong Kong's young people and provide aid to victims of natural disaster or illness. In 2005 Chan created the Dragon's Heart Foundation to help children and the elderly in remote areas of China by building schools, providing books, fees, and uniforms for children; the organization expanded its reach to Europe in 2011. The foundation also provides for the elderly with donations of warm clothing, wheelchairs, and other items.

>> Jackie Chan filmography

Jackie Chan began his film career as a stuntman in the Bruce Lee films Fist of Fury (1972) and Enter the Dragon (1973, pictured). In 1976, Jackie Chan received a telegram from Willie Chan, a film producer in the Hong Kong film industry who had been impressed with Jackie's stunt work. Willie Chan offered him an acting role in a film directed by Lo Wei. Lo had seen Chan's performance in the John Woo film Hand of Death (1976) and planned to model him after Bruce Lee with the film New Fist of Fury. His stage name was changed to Sing Lung (Chinese: 成龍, also transcribed as Cheng Long, literally "become the dragon") to emphasise his similarity to Bruce Lee, whose stage name meant "Little Dragon" in Chinese. The film was unsuccessful because Chan was not accustomed to Lee's martial arts style. Despite the film's failure, Lo Wei continued producing films with similar themes, but with little improvement at the box office.

Chan's first major breakthrough was the 1978 film Snake in the Eagle's Shadow, shot while he was loaned to Seasonal Film Corporation under a two-picture deal. Director Yuen Woo-ping allowed Chan complete freedom over his stunt work. The film established the comedic kung fu genre, and proved refreshing to the Hong Kong audience. Chan then starred in Drunken Master, which finally propelled him to mainstream success.

Upon Chan's return to Lo Wei's studio, Lo tried to replicate the comedic approach of Drunken Master, producing Half a Loaf of Kung Fu and Spiritual Kung Fu. He also gave Chan the opportunity to co-direct The Fearless Hyena with Kenneth Tsang. When Willie Chan left the company, he advised Jackie to decide for himself whether or not to stay with Lo Wei. During the shooting of Fearless Hyena Part II, Chan broke his contract and joined Golden Harvest, prompting Lo to blackmail Chan with triads, blaming Willie for his star's departure. The dispute was resolved with the help of fellow actor and director Jimmy Wang Yu, allowing Chan to stay with Golden Harvest.

Success in the action comedy genre: 1980–1987
Willie Chan became Jackie's personal manager and firm friend, and has remained so for over 30 years. He was instrumental in launching Chan's international career, beginning with his first forays into the American film industry in the 1980s. His first Hollywood film was The Big Brawl in 1980. Chan then played a minor role in the 1981 film The Cannonball Run, which grossed $100 million worldwide. Despite being largely ignored by audiences in favour of established American actors such as Burt Reynolds, Chan was impressed by the outtakes shown at the closing credits, inspiring him to include the same device in his future films.

After the commercial failure of The Protector in 1985, Chan temporarily abandoned his attempts to break into the US market, returning his focus to Hong Kong films.

Back in Hong Kong, Chan's films began to reach a larger audience in East Asia, with early successes in the lucrative Japanese market including The Young Master (1980) and Dragon Lord (1982). The Young Master went on to beat previous box office records set by Bruce Lee and established Chan as Hong Kong cinema's top star. With Dragon Lord, he began experimenting with elaborate stunt action sequences, including the final fight scene where he performs various stunts, including one where he does a back flip off a loft and falls to the lower ground.

Chan produced a number of action comedy films with his opera school friends Sammo Hung and Yuen Biao. The three co-starred together for the first time in 1983 in Project A, which introduced a dangerous stunt-driven style of martial arts that won it the Best Action Design Award at the third annual Hong Kong Film Awards. Over the following two years, the "Three Brothers" appeared in Wheels on Meals and the original Lucky Stars trilogy. In 1985, Chan made the first Police Story film, a US-influenced action comedy in which Chan performed a number of dangerous stunts. It was named the "Best Film" at the 1986 Hong Kong Film Awards. In 1986, Chan played "Asian Hawk," an Indiana Jones-esque character, in the film Armour of God. The film was Chan's biggest domestic box office success up to that point, grossing over HK$35 million.

Acclaimed sequels and Hollywood breakthrough: 1988–1998
In 1988, Chan starred alongside Sammo Hung and Yuen Biao for the last time to date, in the film Dragons Forever. Hung co-directed with Corey Yuen, and the villain in the film was played by Yuen Wah, both of whom were fellow graduates of the China Drama Academy.

In the late 1980s and early 1990s, Chan starred in a number of successful sequels beginning with Project A Part II and Police Story 2, which won the award for Best Action Choreography at the 1989 Hong Kong Film Awards. This was followed by Armour of God II: Operation Condor, and Police Story 3: Super Cop, for which Chan won the Best Actor Award at the 1993 Golden Horse Film Festival. In 1994, Chan reprised his role as Wong Fei-hung in Drunken Master II, which was listed in Time Magazine's All-Time 100 Movies. Another sequel, Police Story 4: First Strike, brought more awards and domestic box office success for Chan, but did not fare as well in foreign markets.

Chan rekindled his Hollywood ambitions in the 1990s, but refused early offers to play villains in Hollywood films to avoid being typecast in future roles. For example, Sylvester Stallone offered him the role of Simon Phoenix, a criminal in the futuristic film Demolition Man. Chan declined and the role was taken by Wesley Snipes.

Chan finally succeeded in establishing a foothold in the North American market in 1995 with a worldwide release of Rumble in the Bronx, attaining a cult following in the United States that was rare for Hong Kong movie stars. The success of Rumble in the Bronx led to a 1996 release of Police Story 3: Super Cop in the United States under the title Supercop, which grossed a total of US$16,270,600. Chan's first huge blockbuster success came when he co-starred with Chris Tucker in the 1998 buddy cop action comedy Rush Hour, grossing US$130 million in the United States alone. This film made him a Hollywood star, after which he wrote his autobiography in collaboration with Jeff Yang entitled I Am Jackie Chan.

Fame in Hollywood and Dramatization: 1999–2007
In 1998, Chan released his final film for Golden Harvest, Who Am I?. After leaving Golden Harvest in 1999, he produced and starred alongside Shu Qi in Gorgeous a romantic comedy that focused on personal relationships and featured only a few martial arts sequences. Although Chan had left Golden Havest in 1999, the company continued to produce and distribute for two of his films, Gorgeous (1999) and The Accidental Spy (2001). Chan then helped create a PlayStation game in 2000 called Jackie Chan Stuntmaster, to which he lent his voice and performed the motion capture. He continued his Hollywood success in 2000 when he teamed up with Owen Wilson in the Western action comedy Shanghai Noon which spawned the sequel Shanghai Knights (2003). He reunited with Chris Tucker for Rush Hour 2 (2001) which was an even bigger success than the original grossing $347 million worldwide. He experimented with special effects with The Tuxedo (2002) and The Medallion (2003) which were not as successful critically or commercially. In 2004 he teamed up with Steve Coogan in the big-budget loose adaptation of Jules Verne's Around the World in 80 Days.

Despite the success of the Rush Hour and Shanghai Noon films, Chan became frustrated with Hollywood over the limited range of roles and lack of control over the filmmaking process. In response to Golden Harvest's withdrawal from the film industry in 2003, Chan started his own film production company, JCE Movies Limited (Jackie Chan Emperor Movies Limited) in association with Emperor Multimedia Group (EMG). His films have since featured an increasing number of dramatic scenes while continuing to succeed at the box office; examples include New Police Story (2004), The Myth (2005) and the hit film Rob-B-Hood (2006).

Chan's next release was the third installment in the Rush Hour series: Rush Hour 3 in August 2007. It grossed US$255 million.[44] However, it was a disappointment in Hong Kong, grossing only HK$3.5 million during its opening weekend.

New experiments and change in style: 2008–present
Filming of The Forbidden Kingdom (released in 2008), Chan's first onscreen collaboration with fellow Chinese actor Jet Li, was completed on 24 August 2007 and the movie was released in April 2008. The movie featured heavy use of effects and wires. Chan voiced Master Monkey in Kung Fu Panda (released in June 2008), appearing with Jack Black, Dustin Hoffman, and Angelina Jolie. In addition, he has assisted Anthony Szeto in an advisory capacity for the writer-director's film Wushu, released on 1 May 2008. The film stars Sammo Hung and Wang Wenjie as father and son.

In November 2007, Chan began filming Shinjuku Incident, a dramatic role featuring no martial arts sequences with director Derek Yee, which sees Chan take on the role of a Chinese immigrant in Japan. The film was released on 2 April 2009. According to his blog, Chan discussed his wishes to direct a film after completing Shinjuku Incident, something he has not done for a number of years. The film expected to be the third in the Armour of God series, and had a working title of Armour of God III: Chinese Zodiac. The film was released on 12 December 2012. Because the Screen Actors Guild did not go on strike, Chan started shooting his next Hollywood movie The Spy Next Door at the end of October in New Mexico.  In The Spy Next Door, Chan plays an undercover agent whose cover is blown when he looks after the children of his girlfriend. In Little Big Soldier, Chan stars, alongside Leehom Wang as a soldier in the Warring States period in China. He is the lone survivor of his army and must bring a captured enemy soldier Leehom Wang to the capital of his province.

In 2010 he starred with Jaden Smith in The Karate Kid, a remake of the 1984 original. This was Chan's first dramatic American film. He plays Mr. Han, a kung fu master and maintenance man who teaches Jaden Smith's character kung fu so he can defend himself from school bullies. His role in The Karate Kid Jackie Chan the Favorite Buttkicker award at the Nickelodeon Kids' Choice Awards in 2011.

In Chan's next movie, Shaolin, he plays the cook of the temple instead of one of the major characters.

His 100th movie, 1911, was released on September 26, 2011. Chan was the co-director, executive producer, and lead star of the movie. While Chan has directed over ten films over his career, this was his first directorial work since Who Am I? in 1998. 1911 premiered in North America on 14 October.

While at the 2012 Cannes Film Festival, Chan announced that he was retiring from action films citing that he was getting too old for the genre. He later clarified that he would not be completely retiring from action films, but would be performing fewer stunts and taking care of his body more.

In 2015, Chan was awarded the title of "Datuk" by Malaysia as he helped Malaysia to boost its tourism, especially in Kuala Lumpur where he previously shot his films. Upcoming films include the Indo-China project titled "Kung Fu Yoga" which also stars Sonu Sood and Amyra Dastur. The film also reunites Chan with director Stanley Tong, who directed a number of Chan's films in the 1990s.
