South Africa

South Africa, officially the Republic of South Africa, is the southernmost sovereign state in Africa. It is bounded on the south by 2,798 kilometers of coastline of southern Africa stretching along the South Atlantic and Indian Oceans, on the north by the neighbouring countries of Namibia, Botswana and Zimbabwe, and on the east by Mozambique and Swaziland, and surrounding the kingdom of Lesotho. South Africa is the 25th-largest country in the world by land area, and with close to 53 million people, is the world's 24th-most populous nation. It is the southernmost country on the mainland of the Old World or the Eastern Hemisphere.

South Africa is a multiethnic society encompassing a wide variety of cultures, languages, and religions. Its pluralistic makeup is reflected in the constitution's recognition of 11 official languages, which is among the highest number of any country in the world. Two of these languages are of European origin: Afrikaans developed from Dutch and serves as the first language of most white and coloured South Africans; English reflects the legacy of British colonialism, and is commonly used in public and commercial life, though it is fourth-ranked as a spoken first language.

Africa

Africa is the world's second-largest and second-most-populous continent. At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers six percent of Earth's total surface area and 20.4 percent of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two de facto independent states with limited or no recognition.

Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4.Algeria is Africa's largest country by area, and Nigeria by population. Africa, particularly central Eastern Africa, is widely accepted as the place of origin of humans and the Hominidae clade (great apes), as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago, including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens (modern human) found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones.

Flight

Flight is the process by which an object moves, through an atmosphere (the air in the case of earth) or beyond it (as in the case of spaceflight) without direct support from any surface. This can be achieved by generating aerodynamic lift, propulsive thrust, aerostatically using buoyancy, or by ballistic movement.

Many things fly, from natural aviators such as birds, bats and insects to human inventions such as missiles, aircraft such as airplanes, helicopters and balloons, to rockets such as spacecraft.

The engineering aspects of flight are studied in aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the air, and astronautics, the study of vehicles that travel through space, and in ballistics, the study of the flight of projectiles.

Types of flight

Buoyant flight

Humans have managed to construct lighter than air vehicles that raise off the ground and fly, due to their buoyancy in air.

An aerostat is a system that remains aloft primarily through the use of buoyancy to give an aircraft the same overall density as air. Aerostats include free balloons, airships, and moored balloons. An aerostat's main structural component is its envelope, a lightweight skin containing a lifting gas to provide buoyancy, to which other components are attached.

Cape Town

Cape Town (Afrikaans: Kaapstad [ˈkɑːpstɐt]; Xhosa: Ikapa) is a city in South Africa. It ranks third among the most populous urban areas in South Africa, after Johannesburg and Durban, and has roughly the same population as the Durban Metropolitan Area. It is also the provincial capital and primate city of the Western Cape. It is the southernmost city on the African continent.

As the seat of the National Parliament it is also the legislative capital of the country. It forms part of the City of Cape Town metropolitan municipality. The city is famous for its harbour, for its natural setting in the Cape Floristic Region, as well as for such well-known landmarks as Table Mountain and Cape Point. As of 2014, it is the 10th most populous city in Africa and home to 64% of the Western Cape's population. It is one of the most multicultural cities in the world, reflecting its role as a major destination for immigrants and expatriates to South Africa. The city was named the World Design Capital for 2014 by the International Council of Societies of Industrial Design. In 2014, Cape Town was named the best place in the world to visit by both The New York Times and The Telegraph.

South African Airways

South African Airways (SAA) is the national flag carrier and largest airline of South Africa, with headquarters in Airways Park on the grounds of OR Tambo International Airport in Kempton Park, Ekurhuleni, Gauteng. The airline flies to 38 destinations worldwide from its hub at OR Tambo International Airport, using a fleet of 54 aircraft. Thuli Mpshe was appointed as the acting CEO of SAA in August after Nico Bezuidenhout, the former acting CEO of SAA returned as CEO of Mango.

South African Airways was founded in 1934 after the acquisition of Union Airways by the South African government. The airline was initially overseen and controlled by South African Railways and Harbours Administration. Sanctions by African countries which would have otherwise provided stopover airports during apartheid forced it to adopt long-range aircraft and other measures to counter these restrictions. During this time, it was also known by its Afrikaans name, Suid-Afrikaanse Lugdiens (SAL), which has been dropped. In 1997 a major overhaul programme, which involved a change of name, image and aircraft livery, as well as the introduction of online ticketing services, was carried out by the company's board. In 2006, SAA split from Transnet, its parent company, to operate as an independent airline.
