Chinook Helicopter Crash (1994)
On 2 June 1994, a Chinook helicopter of the Royal Air Force (RAF), serial number ''ZD576'', crashed on the Mull of Kintyre, Scotland, in foggy conditions. The crash resulted in the deaths of all twenty-five passengers and four crew on board. Among the passengers were almost all the United Kingdom's senior Northern Ireland intelligence experts. The accident is the RAF's fourth-worst peacetime disaster. In 1995, an RAF board of inquiry ruled that it was impossible to establish the exact cause of the accident. This ruling was subsequently overturned by two senior reviewing officers, who stated the pilots were guilty of gross negligence for flying too fast and too low in thick fog. This finding proved to be controversial, especially in light of irregularities and technical issues surrounding the then-new Chinook HC.2 variant which were uncovered. A Parliamentary inquiry conducted in 2001 found the previous verdict of gross negligence on the part of the crew to be 'unjustified'. In ...

Pilot Error
Pilot error generally refers to an Aviation accidents and incidents, accident in which an action or decision made by the Aircraft pilot#Airline, pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. Chicago Convention on International Civil Aviation, Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of the "pilot error" does not include deliberate crash (and such crash is not an accident). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs to teach crew members how t ...

Fort George, Scotland
Fort George is a large 18th-century fortress near Ardersier, to the north-east of Inverness in the Highland council area of Scotland. It was built to control the Scottish Highlands in the aftermath of the Jacobite rising of 1745, replacing a ''Fort George'' in Inverness constructed after the 1715 Jacobite rising to control the area. The current fortress has never been attacked and has remained in continuous use as a garrison. The fortification is based on a star design; it remains virtually unaltered and nowadays is open to visitors with exhibits and facsimiles showing the fort's use at different periods, while still serving as an army barracks. First Fort George The first Fort George was built in 1727 in Inverness; it was a large fortress capable of housing 400 troops on a hill beside the River Ness, on the site of (and incorporating portions of) the medieval castle that had been rebuilt as a citadel by Oliver Cromwell but later abandoned. The first commanding officer of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gross Negligence
Gross negligence is the "lack of slight diligence or care" or "a conscious, voluntary act or omission in reckless disregard of a legal duty and of the consequences to another party." In some jurisdictions a person injured as a result of gross negligence may be able to recover punitive damages from the person who caused the injury or loss. Negligence is the opposite of diligence, or being careful. The standard of ordinary negligence is what conduct deviates from the proverbial "reasonable person". By extension, if somebody has been grossly negligent, that means they have fallen so far below the ordinary standard of care that one can expect, to warrant the label of being "gross". Gross negligence may thus be described as reflecting "the want of even slight or scant care", falling below the level of care that even a careless person would be expected to follow. While some jurisdictions equate the culpability of gross negligence with that of recklessness, most differentiate it from sim ...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strela 2
The 9K32 Strela-2 (russian: Cтрела, "arrow"; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile (or MANPADS) system. It is designed to target aircraft at low altitudes with passive infrared homing guidance and destroy them with a high explosive warhead. Broadly comparable in performance with the US Army FIM-43 Redeye, the Strela-2 was the first Soviet man-portable SAM – full-scale production began in 1970. While the Redeye and 9K32 Strela-2 were similar, the missiles were not identical. The Strela-2 was a staple of the Cold War and was produced in huge numbers for the Soviet Union and their allies, as well as revolutionary movements. Though since surpassed by more modern systems, the Strela and its variants remain in service in many countries, and have seen widespread use in nearly every regional conflict since 1972. Development The end of World War II led to a major shift in Soviet defence policy. The advent of long range, hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurora (aircraft)
Aurora was a rumored mid-1980s American reconnaissance aircraft. There is no substantial evidence that it was ever built or flown and it has been termed a myth."Aurora, Strategic Reconnaissance." ''AerospaceWeb.org.'' Retrieved: 17 October 2010. The U.S. government has consistently denied such an aircraft was ever built. Aviation and space reference site ''Aerospaceweb.org'' concluded, "The evidence supporting the Aurora is circumstantial or pure conjecture, there is little reason to contradict the government's position."

Northern Ireland Peace Process
The Northern Ireland peace process includes the events leading up to the 1994 Provisional Irish Republican Army (IRA) ceasefire, the end of most of the violence of the Troubles, the Good Friday Agreement of 1998, and subsequent political developments. Timeline Towards a ceasefire In 1994, talks between the leaders of the two main Irish nationalist parties in Northern Ireland, John Hume of the Social Democratic and Labour Party (SDLP), and Gerry Adams of Sinn Féin (SF), continued. These talks led to a series of joint statements on how the violence might be brought to an end. The talks had been going on since the late 1980s and had secured the backing of the Irish Government through an intermediary, Father Alec Reid. In November it was revealed that the British government had also been in talks with the Provisional IRA, although they had long denied it. On Wednesday 15 December 1993, the ''Joint Declaration on Peace'' (more commonly known as the Downing Street Declaration) was ...

Hypersonic
In aerodynamics, a hypersonic speed is one that exceeds 5 times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5-10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wake Turbulence
Wake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air. It includes variety of elements, the most significant of which are wingtip vortices and jetwash. Jetwash refers to the rapidly moving gases expelled from a jet engine; it is extremely turbulent but of short duration. Wingtip vortices, however, are much more stable and can remain in the air for up to three minutes after the passage of an aircraft. It is therefore not true turbulence in the aerodynamic sense, as true turbulence would be chaotic. Instead, it refers to the similarity to atmospheric turbulence as experienced by an aircraft flying through this region of disturbed air. Wingtip vortices occur when a wing is generating lift. Air from below the wing is drawn around the wingtip into the region above the wing by the lesser amount of pressure above the wing, causing a vortex to trail from each wingtip. The strength of wingtip vortices is determined primarily by the we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cover-up
A cover-up is an attempt, whether successful or not, to conceal evidence of wrongdoing, error, incompetence, or other embarrassing information. Research has distinguished personal cover-ups (covering up one's own misdeeds) from relational cover-ups (covering up someone else's misdeeds). The expression is usually applied to people in positions of authority who abuse power to avoid or silence criticism or to deflect guilt of wrongdoing. Perpetrators of a cover-up (initiators or their allies) may be responsible for a misdeed, a breach of trust or duty, or a crime. While the terms are often used interchangeably, ''cover-up'' involves withholding incriminatory evidence, while ''whitewash'' involves releasing misleading evidence. See also Misprision. A cover-up involving multiple parties is a type of conspiracy. Modern usage When a scandal breaks, the discovery of an attempt to cover up the truth is often regarded as even more reprehensible than the original deeds. The mi ...

Conspiracy Theory
A conspiracy theory is an explanation for an event or situation that invokes a conspiracy by sinister and powerful groups, often political in motivation, when other explanations are more probable.Additional sources: * * * * The term has a negative connotation, implying that the appeal to a conspiracy is based on prejudice or insufficient evidence. A conspiracy theory is not the same as a conspiracy; instead, it refers to a hypothesized conspiracy with specific characteristics, such as an opposition to the mainstream consensus among those people (such as scientists or historians) who are qualified to evaluate its accuracy. Conspiracy theories resist falsification and are reinforced by circular reasoning: both evidence against the conspiracy and an absence of evidence for it are re-interpreted as evidence of its truth, whereby the conspiracy becomes a matter of faith rather than something that can be proven or disproven. Studies have linked belief in conspiracy theories to dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
