Identified Flying Object
Identifying unidentified flying objects (UFOs) is a difficult task due to the normally poor quality of the evidence provided by those who report sighting the unknown object. Observations and subsequent reporting are often made by those untrained in astronomy, atmospheric phenomena, aeronautics, physics, and perception. Nevertheless, most officially investigated UFO sightings, such as from the U.S. Air Force's Project Blue Book, have been identified as being due to honest misidentifications of natural phenomena, aircraft, or other prosaic explanations. In early U.S. Air Force attempts to explain UFO sightings, unexplained sightings routinely numbered over one in five reports. However, in early 1953, right after the CIA's Robertson Panel, percentages of unexplained sightings dropped precipitously, usually being only a few percent in any given year. When Project Blue Book closed down in 1970, only 6% of all cases were classified as being truly unidentified. UFOs that can be explained ...

Unidentified Flying Object
An unidentified flying object (UFO), more recently renamed by US officials as a UAP (unidentified aerial phenomenon), is any perceived aerial phenomenon that cannot be immediately identified or explained. On investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained. Scientists and skeptic organizations such as the Committee for Skeptical Inquiry have provided prosaic explanations for a large number of claimed UFOs being caused by natural phenomena, human technology, delusions, or hoaxes. Small but vocal groups of ufologists favour unconventional, pseudoscientific hypotheses, often claiming that UFOs are evidence of extraterrestrial intelligence. Beliefs surrounding UFOs have inspired parts of new religions. While unusual sightings have been reported in the sky throughout history, UFOs became culturally prominent after World War II, escalating during the Space Age. The 20th century saw studies and investiga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for ...

Artificial Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propuls ...

CUFOS
The Center for UFO Studies (CUFOS) is a privately funded UFO research group. The group was founded in 1973 by J. Allen Hynek, who at the time was chair of the Department of Astronomy at Northwestern University in Illinois.Franch John, ''The Secret Life of J. Allen Hynek''. Skeptical Inquirer Volume 37.1, January/February 2013 History Hynek was a scientific consultant for Project Blue Book, the United States Air Force official study of the UFO phenomenon from 1948 to 1969. Although Hynek started out as a skeptic and helped the Air Force to debunk most UFO reports, he gradually became convinced that a small number of UFO cases were not hoaxes or explainable as misidentifications of natural phenomena, and that these cases might represent something extraordinary — even alien visitation from other planets. When the Air Force shut down Project Blue Book in 1969, Hynek, in 1973, founded the Center for UFO Studies (CUFOS) to continue to collect and study UFO reports. Ufologist Jam ...

Allan Hendry
Allan Hendry (born 1950) is an American astronomer and ufologist. UFO historian Jerome Clark calls him "one of the most skilled investigators in the history of UFO research." ''page 481'' He was the main investigator for the Center for UFO Studies (CUFOS) in the 1970s. Education and career Hendry earned a B.A. in astronomy from the University of Michigan in 1972. UFO research Hendry was hired for CUFOS by the organization's founder, J. Allen Hynek, who was seeking a full-time investigator with scientific expertise and an open-minded attitude, and who was neither a debunker nor a "UFO believer". As the chief investigator for CUFOS during most of the 1970s, Hendry personally investigated over 1000 UFO reports. He was able to find mundane explanations for the vast majority of UFO cases, but he also judged a small percentage of cases to be unexplained. One of the most famous "unexplained" cases he investigated was the Val Johnson Incident in 1979, in which a deputy sheriff in M ...

Office Of The Director Of National Intelligence
The director of national intelligence (DNI) is a senior, cabinet-level United States government official, required by the Intelligence Reform and Terrorism Prevention Act of 2004 to serve as executive head of the United States Intelligence Community (IC) and to direct and oversee the National Intelligence Program (NIP). All IC agencies report directly to the DNI. The DNI also serves, upon invitation, as an advisor to the president of the United States, the National Security Council and the Homeland Security Council on all intelligence matters. The DNI, supported by the Office of the Director of National Intelligence (ODNI), produces the President's Daily Brief (PDB), a top-secret document including intelligence from all IC agencies, handed each morning to the president of the United States. President George W. Bush strengthened the role of the DNI on July 30, 2008, with Executive Order 13470, which, among other things, solidified the DNI's authority to set goals for intel ...

NICAP
The National Investigations Committee On Aerial Phenomena (NICAP) is an unidentified flying object (UFO) research group most active in the United States from the 1950s to the 1980s. It remains active primarily as an informational depository on the UFO phenomenon. Overview NICAP was a non-profit organization and faced financial collapse many times in its existence, due in no small part to business ineptitude among the group's directors. Following a wave of nationally publicized UFO incidents in the mid-1960s, NICAP's membership spiked dramatically and only then did the organization become financially stable. However, following publication of the Condon Report in 1968, NICAP's membership declined sharply, and the organization again fell into long-term financial decline and disarray. Despite these internal troubles, NICAP probably had the most visibility of any civilian American UFO group, and arguably had the most mainstream respectability; Jerome Clark writes that "for many middle ...

American Institute Of Aeronautics And Astronautics
The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of the Aeronautical Sciences. In 2015, it had more than 30,000 members among aerospace professionals worldwide (a majority are American and/or live in the United States). History The AIAA was founded in 1963 from the merger of two earlier societies: the American Rocket Society (ARS), founded in 1930 as the American Interplanetary Society (AIS), and the Institute of the Aerospace Sciences (IAS), founded in 1932 as the Institute of the Aeronautical Sciences. Paul Johnston was the first executive director of the organization. Jim Harford took his seat after 18 months. The newly-formed structure gathered 47 technical committees and one broad technical publication, the ''AIAA Journal''. The ''AIAA Student Journal'' was also launched in 1963. T ...

Condon Committee
The Condon Committee was the informal name of the University of Colorado UFO Project, a group funded by the United States Air Force from 1966 to 1968 at the University of Colorado to study unidentified flying objects under the direction of physicist Edward Condon. The result of its work, formally titled Scientific Study of Unidentified Flying Objects, and known as the Condon Report, appeared in 1968. After examining hundreds of UFO files from the Air Force's Project Blue Book and from the civilian UFO groups National Investigations Committee On Aerial Phenomena (NICAP) and Aerial Phenomena Research Organization (APRO), and investigating sightings reported during the life of the Project, the Committee produced a ''Final Report'' that said the study of UFOs was unlikely to yield major scientific discoveries. The Report's conclusions received a mixed reception from scientists and academic journals. The report has been cited as a decisive factor in the generally low level of interes ...
