United Airlines Flight 826
On December 28, 1997, United Airlines Flight 826 was operated by a Boeing 747-100 flying from New Tokyo Airport (which changed its name to Narita International Airport in 2004), Japan to Honolulu International Airport, Hawaii. Two hours into the flight, at an altitude of , the plane received reports of severe clear-air turbulence in the area and the seat belt sign was turned on. Moments later, the aircraft suddenly dropped around , seriously injuring 15 passengers and 3 crew members. The plane turned around and landed safely back in Tokyo, but one passenger, a 32-year-old Japanese woman, died. " |
Clear-air Turbulence
In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet. The atmospheric region most susceptible to CAT is the high troposphere at altitudes of around as it meets the tropopause. Here CAT is most frequently encountered in the regions of jet streams. At lower altitudes it may also occur near mountain ranges. Thin cirrus clouds can also indicate high probability of CAT. CAT can be hazardous to the comfort, and occasionally the safety, of air travelers. CAT in the jet stream is expected to become stronger and more frequent because of climate change, with transatlantic wintertime CAT increasing by 59% (light), 94% (moderate), and 149% (severe) by the time of doubling. Detection Clear-air turbulence is usually impossible to detect with the naked eye and very difficult to detect with a conventional radar, with the result that ...

Accidents And Incidents Involving The Boeing 747
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into some ...

Aviation Accidents And Incidents In 1997
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Data Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to as a "black box", an outdated name which has become a misnomer—they are now required to be painted bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the International Civil Aviation Organiza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midway Atoll
Midway Atoll (colloquial: Midway Islands; haw, Kauihelani, translation=the backbone of heaven; haw, Pihemanu, translation=the loud din of birds, label=none) is a atoll in the North Pacific Ocean. Midway Atoll is an insular area of the United States and is an unorganized and unincorporated territory. The largest island is Sand Island, which has housing and an airstrip. Immediately to the east of Sand Island across the narrow Brooks Channel is Eastern Island, which is uninhabited and no longer has any facilities. Forming a rough, incomplete circle around the two main islands and creating Midway Lagoon is Spit Island, a narrow reef. Roughly equidistant between North America and Asia, Midway is the only island in the Hawaiian Archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time ( UTC−11:00, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the Hawaii–Aleutian Time Zone ...

Henderson Field (Midway Atoll)
Henderson Field is a public airport located on Sand Island in Midway Atoll, an unincorporated territory of the United States. The airport is used as an emergency diversion point for ETOPS operations. It is one of three airfields named after Major Lofton R. Henderson (killed in the Battle of Midway during WWII), together with Henderson Field on Midway's Eastern Island, and Henderson Field in the Solomon Islands. The airfield now provides access to Midway Atoll National Wildlife Refuge. The airfield operated until 1993 as Naval Air Facility Midway. Its construction was begun by Seabees of the 1st Naval Construction Battalion in July 1942 as a bomber strip. After transition from the U.S. Navy to the Department of the Interior, the airport was subsidized by Boeing until 2004. Since 2004, the U.S. Fish and Wildlife Service has fully supported airport operations and maintenance with some assistance from the Federal Aviation Administration. Henderson Field has no control tower. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purser
A purser is the person on a ship principally responsible for the handling of money on board. On modern merchant ships, the purser is the officer responsible for all administration (including the ship's cargo and passenger manifests) and supply. Frequently, the cooks and stewards answer to the purser as well. They were also called a pusser in British naval slang.From which the Pusser's brand of rum takes its name. History The purser joined the warrant officer ranks of the Royal Navy in the early 14th century and existed as a naval rank until 1852. The development of the warrant officer system began in 1040, when five English ports began furnishing warships to King Edward the Confessor in exchange for certain privileges. They also furnished crews whose officers were the Master, Boatswain, Carpenter and Cook. Later these officers were "warranted" by the British Admiralty. Pursers received no pay but were entitled to profits made through their business activities. In the 18th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
