Boricua Popular Army
The ("Puerto Rican people#Boricua, Boricua Popular/People's Army"), also known as ("The Machete Wielders"), is a clandestine operation, clandestine militant and insurgent organization based in Puerto Rico, with cells in the broader US and other nations. It campaigns for, and supports, the independence of Puerto Rico from the United States. During their first decade of existence, they had an average of two actions per year. The group claimed responsibility for the 1978 bombing of a small power station in the San Juan area, the 1979 retaliation attacks against the United States armed forces personnel, the Puerto Rico Air National Guard#1981 Muñiz Air National Guard Base attack, 1981 Muñiz Air National Guard Base attack, and a Águila Blanca (heist), 1983 Wells Fargo bank robbery. Boricua Popular Army was led primarily by former FBI Most Wanted Fugitives, FBI fugitive Filiberto Ojeda Ríos until he was killed by the FBI in 2005.

Soviet Navy
The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its Warsaw Pact, sphere of influence in eastern Europe.

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas Aircraft Company
The Douglas Aircraft Company was an American aerospace manufacturer, aerospace and military, defense company based in Southern California. Founded in 1921 by Donald Wills Douglas Sr., it merged with McDonnell Aircraft in 1967 to form McDonnell Douglas, where it operated as a division. History 1920s The company was founded as the Douglas Company by Donald Wills Douglas Sr. on July 22, 1921, in Santa Monica, California, following dissolution of the Davis-Douglas Company. An early claim to fame was the first aerial circumnavigation, first circumnavigation of the world by air in Douglas airplanes in 1924. In 1923, the U.S. Army Air Service was interested in carrying out a mission to circumnavigate the Earth for the first time by aircraft, a program called "World Flight". Donald Douglas proposed a modified Douglas DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been produced for the United States Navy, U.S. Navy.Rumerman, Judy. "The D ...

Donald Wills Douglas, Sr
Donald is a Scottish masculine given name. It is derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers. A short form of Donald is Don, and pet forms of Donald include Donnie and Donny. The feminine given name Donella is derived from Donald. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name '' Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.

Boeing 707
The Boeing 707 is an early American long-range Narrow-body aircraft, narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype, the initial first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 is a swept wing four-engined jet aircraft, quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later Boeing 720, 720, Boeing 727, 727, Boeing 737, 737, and Boeing 757, 757 models.

Pan American World Airways
Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as Wide-body aircraft, jumbo jets and computerized reservation systems, and introduced the Boeing 707, first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the le ...
