Uruguayan Air Force Flight 571 was the chartered flight of a Fairchild FH-227D from Montevideo, Uruguay, to Santiago, Chile, that crashed in the Andes mountains in Argentina on 13 October 1972. The accident and subsequent survival became known as both the Andes flight disaster (, literally Tragedy of the Andes) and the Miracle of the Andes (). The inexperienced co-pilot, Lieutenant-Colonel Dante Héctor Lagurara, was piloting the aircraft at the time of the accident. He mistakenly believed the aircraft had overflown Curicó, the turning point to fly north, and began descending towards what he thought was the Pudahuel Airport in Santiago de Chile. He failed to notice that the instrument readings indicated that he was still east of Curicó. Lagurara, upon regaining visual flight conditions, saw the mountain and unsuccessfully tried to gain altitude. The aircraft struck a mountain ridge, shearing off both wings and the tail cone. The remaining portion of the fuselage slid down a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, fully under pilot control, is unintentionally flown into the ground, a body of water or other obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending collision until impact, or it is too late to avert. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are classified instead as uncontrolled flight into terrain, or UFIT. Incidents resulting from the deliberate action of the person at the controls, such as a forced landing, an act of terrorism, or suicide by pilot, are also excluded from the definition of CFIT. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircra ...

Chile
Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Pacific Ocean. Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of , sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández Islands, Juan Fernández, Isla Salas y Gómez, Desventuradas Islands, Desventuradas, and Easter Island, and claims about of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish language, Spanish. Conquest of Chile, Spain conquered and colonized the region in the mid-16th century, replacing Incas in Central Chile, Inca rule; however, they Arauco War ...

Avalanche
An avalanche is a rapid flow of snow down a Grade (slope), slope, such as a hill or mountain. Avalanches can be triggered spontaneously, by factors such as increased precipitation or snowpack weakening, or by external means such as humans, other animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, Mudflow, mudslides, Landslide#Debris landslide, rock slides, and serac collap ...

Starvation
Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage and eventually, death. The term ''inanition'' refers to the symptoms and effects of starvation. Starvation by outside forces is a crime according to international criminal law and may also be used as a means of torture or execution. According to the World Health Organization (WHO), hunger is the single gravest threat to the world's public health. The WHO also states that malnutrition is by far the biggest contributor to child mortality, present in half of all cases. Undernutrition is a contributory factor in the death of 3.1 million children under five every year. The results also demonstrates that as global hunger levels have stabilized, however, despite some progress in specific areas such as stunting and exclusive breastfeeding, an alarming number of ...

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs (such as K9 units); urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organisation that promotes the exchange of information between national urban search and rescue organisations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Armed Forces and Canadian Coast Guard: "Search and Rescue comprises the search for, and provision of ai ...

Rugby Union
Rugby union football, commonly known simply as rugby union in English-speaking countries and rugby 15/XV in non-English-speaking world, Anglophone Europe, or often just rugby, is a Contact sport#Terminology, close-contact team sport that originated at Rugby School in England in the first half of the 19th century. Rugby is based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an Rugby ball, oval-shaped ball on a rectangular field called a pitch. The field has H-shaped Goal (sports)#Structure, goalposts at both ends. Rugby union is a popular sport around the world, played by people regardless of gender, age or size. In 2023, there were more than 10 million people playing worldwide, of whom 8.4 million were registered players. World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, a ...

Old Christians Club
Old Christians Club, or simply Old Christians, is a Uruguayan sports club from the Carrasco neighbourhood of Montevideo. The club is known mostly for its rugby union team that became famous around the world due to the 1972 Uruguayan Air Force Flight 571 crash that involved the first division team of the club. Old Christians currently plays in Primera División, the top division of local rugby system. Apart from rugby union, the club also hosts football and field hockey branches. History Old Christians Club was founded in 1962 by alumni of the Christian Brothers, Stella Maris College, one of Montevideo's best high schools. The institution started as a rugby union club and, like most rugby clubs in Uruguay and Argentina, also developed a field hockey section for girls, thus becoming a multi-sports club. Flight 571 disaster On October 13, 1972, a plane carrying five crew members and 40 players and associates of Old Christians' rugby team crashed in the remote Andes, en r ...

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...

Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

Ridge
A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements. Classification As in the case of landforms in general, there is a lack of any commonly agreed clas ...

Visual Flight
Visual flight or visual attitude flying is the control of an aircraft via outside references (such as the sky or the runway in takeoff). For aircraft, the primary visual reference used is usually the relationship between the aircraft's "nose" or cowling against the natural horizon. Regulations for visual flights are under a separate set of visual flight rules. The pilot can maintain or change the airspeed, altitude, and direction of flight ( heading) as well as the rate of climb or rate of descent and rate of turn ( bank angle) through the use of the aircraft flight controls and aircraft engine controls to adjust the "sight picture". Some reference to flight instruments Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in f ... is usually necessary to determine exact airspeed, altitude, h ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for ...
