1961 Ndola Transair Sweden DC-6 Crash
On 18 September 1961, a DC-6 passenger aircraft of Transair Sweden Flight 001, operating for the United Nations, crashed near Ndola, Northern Rhodesia (present-day Zambia). The crash resulted in the deaths of all people on board, including Dag Hammarskjöld, the second secretary-general of the United Nations, and 15 others. Hammarskjöld had been ''en route'' to ceasefire negotiations with Moïse Tshombe during the Congo Crisis. Three official inquiries failed to conclusively determine the cause. Some historians and military experts like Susan Williams have criticized the official inquiries, pointing to evidence of foul play that had been omitted from the inquiries. Hammarskjöld's death caused a succession crisis at the United Nations when the Security Council was tasked with selecting his successor. Aircraft and crew The aircraft was a Douglas DC-6B, c/n 43559/251, registered in Sweden as SE-BDY, first flown in 1952 and powered by four Pratt & Whitney R-2800 18- ...

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 ...

Congo Crisis
The Congo Crisis (french: Crise congolaise, link=no) was a period of political upheaval and conflict between 1960 and 1965 in the Republic of the Congo (today the Democratic Republic of the Congo). The crisis began almost immediately after the Congo became independent from Belgium and ended, unofficially, with the entire country under the rule of Joseph-Désiré Mobutu. Constituting a series of civil wars, the Congo Crisis was also a proxy conflict in the Cold War, in which the Soviet Union and the United States supported opposing factions. Around 100,000 people are believed to have been killed during the crisis. A nationalist movement in the Belgian Congo demanded the end of colonial rule: this led to the country's independence on 30 June 1960. Minimal preparations had been made and many issues, such as federalism, tribalism, and ethnic nationalism, remained unresolved. In the first week of July, a mutiny broke out in the army and violence erupted between black and whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

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] |

Lieutenant Colonel
Lieutenant colonel ( , ) is a rank of commissioned officers in the armies, most marine forces and some air forces of the world, above a major and below a colonel. Several police forces in the United States use the rank of lieutenant colonel. The rank of lieutenant colonel is often shortened to simply "colonel" in conversation and in unofficial correspondence. Sometimes, the term 'half-colonel' is used in casual conversation in the British Army. In the United States Air Force, the term 'light bird' or 'light bird colonel' (as opposed to a 'full bird colonel') is an acceptable casual reference to the rank but is never used directly towards the rank holder. A lieutenant colonel is typically in charge of a battalion or regiment in the army. The following articles deal with the rank of lieutenant colonel: * Lieutenant-colonel (Canada) * Lieutenant colonel (Eastern Europe) * Lieutenant colonel (Turkey) * Lieutenant colonel (Sri Lanka) * Lieutenant colonel (United Kingdom) * L ...

Thomas Dunne Books
Thomas Dunne Books was an imprint of St. Martin's Press, which is a division of Macmillan Publishers. From 1986 until April 2020, it published popular trade fiction and nonfiction. History The imprint signed David Irving, a scholar, for a Joseph Goebbels biography in 1996 but had to drop the book when it was found out that Irving was a Holocaust denier for having links to Institute for Historical Review, "the literary center of the United States Holocaust-denial movement." In October 1999, St. Martin's Press recalled a Dunne book, ''Fortunate Son: George W. Bush and the Making of an American President'', and destroyed them after various incidents about the author, J. H. Hatfield, surfaced. The incidents were that he had served prison time for a car-bombing attempt on his former boss's life and that he included an anonymous accusation about Bush. A St. Martin's executive editor resigned in protest over the publication. In November, Dunne editors stopped attending St. Martin edito ...

Pratt & Whitney R-2800
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of , and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade the engine, including water injection for takeoff in cargo and passenger planes and to give emergency power in combat. Design and development First run in 1937, near the time that the larger competing 18-cylinder Wright Duplex-Cyclone's development had been started in May of that year, the displacement R-2800 was first-flown by 1940, one year before the Duplex-Cyclone. The Double Wasp was more powerful than the world's only other modern 18-cylinder engine, the Gnome-Rhône 18L of . The Double Wasp was much smaller in displacement than either of the other 18-cylinder designs, and heat dissipation was a gr ...
