The Battle of Palmdale was the attempted shoot-down of a runaway drone by United States Air Force interceptors in the skies over Southern California in mid-August 1956. The drone was launched from Point Mugu Naval Air Station and soon went out of control. Interceptor aircraft took off from Oxnard Air Force Base and caught up with the drone, but were ultimately unable to bring it down, in spite of expending all of their rockets. After it ran out of fuel, the unmanned aircraft crashed in a sparsely populated tract of desert.

During the incident over 1000 acres were scorched and a substantial amount of property was damaged or destroyed.

Henry Alfred Kissinger (; German: [ˈkΙͺsΙͺŋɐ]; born Heinz Alfred Kissinger, May 27, 1923) is an American diplomat, political theorist, geopolitical consultant, and politician who served as United States Secretary of State and National Security Advisor under the presidential administrations of Richard Nixon and Gerald Ford. For his actions negotiating a ceasefire in Vietnam, Kissinger received the 1973 Nobel Peace Prize under controversial circumstances.

Kissinger was a Jewish refugee who fled Nazi Germany with his family in 1938. Upon arriving in the United States, he excelled academically and graduated from Harvard College in 1950, where he studied under William Yandell Elliott. He earned his M.A. and Ph.D. degrees at Harvard University in 1951 and 1954, respectively.

A practitioner of Realpolitik, Kissinger played a prominent role in United States foreign policy between 1969 and 1977, pioneering the policy of dΓ©tente with the Soviet Union, orchestrating an opening of relations with the People's Republic of China, engaging in what became known as shuttle diplomacy in the Middle East to end the Yom Kippur War, and negotiating the Paris Peace Accords, which ended American involvement in the Vietnam War. Kissinger has also been associated with such controversial policies as the U.S. bombing of Cambodia during the Vietnam War, U.S. involvement in the 1973 Chilean military coup, a "green light" to Argentina's military junta for their Dirty War, and U.S. support for Pakistan during the Bangladesh Liberation War despite a genocide being perpetrated by Pakistan. After leaving government, he formed Kissinger Associates, an international geopolitical consulting firm. Kissinger has written over a dozen books on diplomatic history and international relations.

Kissinger remains a controversial and polarizing figure in U.S. politics, both venerated by some as a highly effective U.S. Secretary of State and condemned by others for allegedly tolerating or supporting war crimes committed by allied nation states during his tenure. A 2015 survey of top international relations scholars, conducted by College of William & Mary, ranked Kissinger as the most effective U.S. secretary of state in the 50 years to 2015. A centenarian, Kissinger is the oldest living former U.S. Cabinet member and the last surviving member of Nixon's Cabinet. The previous oldest cabinet member was George Shultz, who died at the age of 100 in February 2021.

πŸ”— McNamara Fallacy

πŸ”— United States πŸ”— Military history πŸ”— Philosophy πŸ”— Philosophy/Logic πŸ”— Military history/Military biography

The McNamara fallacy (also known as the quantitative fallacy), named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.

The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.

The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam Warβ€”specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.

Operation Epsilon was the codename of a program in which Allied forces near the end of World War II detained ten German scientists who were thought to have worked on Nazi Germany's nuclear program. The scientists were captured between May 1 and June 30, 1945, as part of the Allied Alsos Mission, mainly as part of its Operation Big sweep through southwestern Germany.

They were interned at Farm Hall, a bugged house in Godmanchester, near Cambridge, England, from July 3, 1945, to January 3, 1946. The primary goal of the program was to determine how close Nazi Germany had been to constructing an atomic bomb by listening to their conversations.

Tired mountain syndrome is a condition in which underground nuclear testing fractures and weakens rock, increasing permeability and the risk of release of radionuclides and radioactive contamination of the environment. Locations said to have undergone the syndrome include the French Polynesian island of Moruroa, Rainier Mesa in the United States, the Dnepr 1 nuclear test site on the Kola Peninsula in Russia, possibly Mount Lazarev in the Novaya Zemlya Test Site in Russia, and Mount Mantap in North Korea.

πŸ”— Defenestrations of Prague

The Defenestrations of Prague (Czech: PraΕΎskΓ‘ defenestrace, German: Prager Fenstersturz, Latin: Defenestratio Pragensis) were three incidents in the history of Bohemia in which people were defenestrated (thrown out of a window). Though already existing in Middle French, the word defenestrate ("out of the window") is believed to have first been used in English in reference to the episodes in Prague in 1618 when the disgruntled Protestant estates threw two royal governors and their secretary out of a window of the Hradčany Castle and wrote an extensive apologia explaining their action. In the Middle Ages and early modern times, defenestration was not uncommonβ€”the act carried elements of lynching and mob violence in the form of murder committed together.

The first governmental defenestration occurred in 1419, the second in 1483 and the third in 1618, although the term "Defenestration of Prague" more commonly refers to the third. Often, however, the 1483 event is not recognized as a "significant defenestration", which leads to some ambiguity when the 1618 defenestration is referred to as the "second Prague defenestration". The first and third defenestrations helped to trigger a prolonged religious conflict inside Bohemia (the Hussite Wars, 1st defenestration) or beyond (Thirty Years' War, 3rd defenestration), while the second helped establish a religious peace in the country for 31 years (Peace of KutnΓ‘ Hora, 2nd defenestration).

A synchronization gear, or a gun synchronizer, sometimes rather less accurately called an interrupter, is attached to the armament of a single-engine tractor-configuration aircraft so it can fire through the arc of its spinning propeller without bullets striking the blades. The idea presupposes a fixed armament directed by aiming the aircraft in which it is fitted at the target, rather than aiming the gun independently.

There are many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two has to operate.

Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 1910). However, the first practicalβ€”if far from reliableβ€”gear to enter operational service was that fitted to the Eindecker monoplane fighters, which entered squadron service with the German Air Service in mid-1915. The success of the Eindecker led to numerous gun synchronization devices, culminating in the reasonably reliable hydraulic British Constantinesco gear of 1917. By the end of the war German engineers were well on the way to perfecting a gear using an electrical rather than a mechanical or hydraulic link between the engine and the gun, with the gun being triggered by a solenoid rather than by a mechanical "trigger motor".

From 1918 to the mid-1930s the standard armament for a fighter aircraft remained two synchronized rifle-calibre machine guns, firing forward through the arc of the propeller. During the late 1930s, however, the main role of the fighter was increasingly seen as the destruction of large, all-metal bombers, for which the "traditional" light armament was inadequate.

Since it was impractical to try to fit more than one or two extra guns in the limited space available in the front of a single-engine aircraft's fuselage, this led to an increasing proportion of the armament being mounted in the wings, firing outside the arc of the propeller. There were in fact some advantages in dispensing with centrally mounted guns altogether. Nevertheless, the conclusive redundancy of synchronization gears did not finally come until the introduction of jet propulsion and the absence of a propeller for guns to be synchronized with.

The Aircraft Nuclear Propulsion (ANP) program and the preceding Nuclear Energy for the Propulsion of Aircraft (NEPA) project worked to develop a nuclear propulsion system for aircraft. The United States Army Air Forces initiated Project NEPA on May 28, 1946. NEPA operated until May 1951, when the project was transferred to the joint Atomic Energy Commission (AEC)/USAF ANP. The USAF pursued two different systems for nuclear-powered jet engines, the Direct Air Cycle concept, which was developed by General Electric, and Indirect Air Cycle, which was assigned to Pratt & Whitney. The program was intended to develop and test the Convair X-6, but was cancelled in 1961 before that aircraft was built. The total cost of the program from 1946 to 1961 was about $1 billion.

The Soviet RDS-202 hydrogen bomb (code name Ivan or Vanya), known by Western nations as Tsar Bomba (Russian: Π¦Π°Ρ€ΡŒ-бо́мба, tr. Tsar'-bΓ³mba, IPA:Β [tΝ‘sarΚ² ˈbombΙ™], lit. 'Tsar bomb'), was the most powerful nuclear weapon ever created. Tested on 30Β October 1961 as an experimental verification of calculation principles and multi-stage thermonuclear weapon designs, it also remains the most powerful human-made explosive ever detonated.

The bomb was detonated at the Sukhoy Nos ("Dry Nose") cape of Severny Island, Novaya Zemlya, 15Β km (9.3Β mi) from Mityushikha Bay, north of Matochkin Strait. The detonation was secret but was detected by US Intelligence agencies. The US apparently had an instrumented KC-135R aircraft (Operation SpeedLight) in the area of the test – close enough to have been scorched by the blast.

The bhangmeter results and other data suggested the bomb yielded about 58 megatons of TNT [Mt] (240Β PJ), and that was the accepted yield in technical literature until 1991 when Soviet scientists revealed that their instruments indicated a yield of 50Β Mt (210Β PJ). As they had the instrumental data and access to the test site, their yield figure has been accepted as more accurate. In theory, the bomb would have had a yield in excess of 100Β Mt (420Β PJ) if it had included a uranium-238 tamper but, because only one bomb was built, that capability has never been demonstrated.

The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Research Institute of Technical Physics, at Snezhinsk.
