William A. Cassidy
William A. Cassidy (3 January 1928 – 22 March 2020) was an American geologist and professor emeritus of Geology and Planetary Science at the University of Pittsburgh. Cassidy was responsible for recognizing that Antarctica represented the greatest repository of meteorites on earth. Starting in the early 1970s, Cassidy led most major meteorite expeditions to the south polar region, and in 1979, he was awarded the Antarctica Service Medal. Bill Cassidy founded and led ANSMET from 1976 to 1993. The Cassidy Glacier in Antarctica is named for him, the mineral Cassidyite, and the asteroid 3382 Cassidy. Cassidy assisted the NTSB with the investigation into TWA flight 800. Cassidy estimated that a meteor strike that could damage an aircraft would occur over the US only once every 59,000 to 77,000 years.

Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

3382 Cassidy
__NOTOC__ Year 338 ( CCCXXXVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Ursus and Polemius (or, less frequently, year 1091 ''Ab urbe condita''). The denomination 338 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Allan Hills
The Allan Hills are a group of hills at the end of the Transantarctic Mountains System, located in Oates Land and Victoria Land regions of Antarctica. They are mainly ice free and about long, lying just north-west of the Coombs Hills near the heads of Mawson Glacier and Mackay Glacier. They were mapped by the New Zealand party (1957–58) of the Commonwealth Trans-Antarctic Expedition and named for Professor R. S. Allan of the University of Canterbury, New Zealand. Allan Hills is referred to as the ''Allan Nunatak'', and mapped north of Carapace Nunatak, in the memoirs of the Scott Base Leader Adrian Hayter. Both names are in the USGS listing. Meteorites According to William A. Cassidy, describing the 1976–1977 ANSMET meteorite collecting season, "Looking across the Mackay Glacier at the great sky-blue patches of ice beyond Mount Brooke, we were looking for the first time at ice that had a tremendous upstream collecting area. We were looking at Meteorite Heaven... Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TWA Flight 800
Trans World Airlines Flight 800 (TWA800) was a Boeing 747-100 that exploded and crashed into the Atlantic Ocean near East Moriches, New York, on July 17, 1996, at about 8:31pm.

All 230 people on board died in the crash; it is the third-deadliest Aviation accidents and incidents, aviation accident in U.S. history. Accident investigators from the National Transportation Safety Board (NTSB) traveled to the scene, arriving the following morning amid speculation that a terrorist attack was the cause of the crash. Consequently, the Federal Bureau of Investigation (FBI) and New York City Police Department, New York Police Department Joint Terrorism Task Force (JTTF) initiated a parallel criminal investigation. Sixteen months later, the JTTF announced that no evidence of a criminal act had been found and closed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Cassidy Glacier
__NOTOC__ The Taylor Glacier is an Antarctic glacier about long, flowing from the plateau of Victoria Land into the western end of Taylor Valley, north of the Kukri Hills, south of the Asgard Range. The middle part of the glacier is bounded on the north by the Inland Forts and on the south by Beacon Valley. History The glacier was discovered by the British National Antarctic Expedition (1901–04) and at that time thought to be a part of Ferrar Glacier. The Western Journey Party of the British Antarctic Expedition of 1910 determined that the upper and lower portions of what was then known as Ferrar Glacier are apposed, i.e., joined in Siamese-twin fashion north of Knobhead. With this discovery Robert Falcon Scott named the upper portion for Thomas Griffith Taylor, geologist and leader of the Western Journey Party. Glaciology Research The Taylor Glacier has been the focus of a measurement and modeling effort carried out by researchers from the University of Calif ...
