TWA Flight 800
Trans World Airlines Flight 800 (known as TW800 or TWA800) was a regularly scheduled international passenger flight from John F. Kennedy International Airport in New York City, United States, to Fiumicino Airport in Rome, Italy, with a stopover at Charles de Gaulle Airport in Paris, France. On July 17, 1996, at approximately 8:31p.m. EDT, twelve minutes after takeoff, the Boeing 747-100 exploded and crashed into the Atlantic Ocean near East Moriches, New York, United States. All 230 people on board died in the crash; it is the third-deadliest 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. The Federal Bureau of Investigation (FBI) and New York Police Department Joint Terrorism Task Force (JTTF) initiated a parallel criminal investigation. Sixteen months later, the JTTF announced that no ev ... [...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 three regional offices, located in Anchorage, Alaska; Aurora, Colorado; and Federal Way, Washington. The agency also operated 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 time the CAA/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ellinikon International Airport
Ellinikon International Airport , sometimes spelled ''Hellinikon'', was an international airport that served Athens, Greece, for 63 years. Following its closure on 28 March 2001, it was replaced by the new Athens International Airport, Athens International Airport ''Eleftherios Venizelos''. The airport was located south of Athens, and just west of Glyfada. It was named after the village of Elliniko, now a suburb of Athens. The airport had an official capacity of 11 million passengers per year, but served 13.5 million passengers during its last year of operations. A large portion of the site was converted into a stadium and sports facilities for the 2004 Summer Olympics, 2004 Olympic Games. The former airport is now the site of a major development for coastal Athens, which came under criticism because well-preserved historic buildings (from the 1930s) were demolished. In 2020, construction began on the Hellenikon Metropolitan Park, a complex consisting of luxury homes, hotels, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inerting System
An inerting system decreases the probability of combustion of flammable materials stored in a confined space. The most common such system is a fuel tank containing a combustible liquid, such as gasoline, diesel fuel, aviation fuel, jet fuel, or rocket propellant. After being fully filled, and during use, there is a space above the fuel, called the ullage, that contains evaporated fuel mixed with air, which contains the oxygen necessary for combustion. Under the right conditions this mixture can ignite. An inerting system replaces the air with a gas that cannot support combustion, such as nitrogen. Principle of operation Three elements are required to initiate and sustain combustion in the ullage: an ignition source (heat), fuel, and oxygen. Combustion may be prevented by reducing any one of these three elements. In many cases there is no ignition source, e.g. storage tanks. If the presence of an ignition source can not be prevented, as is the case with most tanks that feed fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arcing
An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field emission. After initiation, the arc relies on thermionic emission of electrons from the electrodes supporting the arc. An arc discharge is characterized by a lower voltage than a glow discharge. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp". Techniques for arc suppression can be used to reduce the duration or likelihood of arc formation. In the late 19th century, electric arc lighting was in wide use for public lighting. Some low-pressure electric arcs are used in many applications. For example, fluorescent tubes, mercury, sodium, and metal-halide lamps are used for lighting; xenon arc lamps have been used for movie projectors. Electric ar ...

Aircraft Fuel Tanks
Aircraft fuel tanks are a major component of aircraft fuel systems. They can be classified into internal or external fuel tanks and can be further classified by method of construction or intended use. Safety aspects of aircraft fuel tanks were examined during the investigation of the 1996 TWA Flight 800 in-flight explosion accident. Internal tanks Integral tanks Integral tanks are areas inside the aircraft structure that have been sealed to allow fuel storage. An example of this type is the "wet wing", commonly used in larger aircraft. Since these tanks are part of the aircraft structure, they cannot be removed for service or inspection. Inspection panels must be provided to allow internal inspection, repair, and overall servicing of the tank. Most large transport aircraft use this system to store fuel in the wings, fuselage and empennage of the aircraft.Whitford 2004, p. 153. Rigid removable tanks Rigid removable tanks are installed in a compartment designed to accommodate the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Terrorism Task Force
A Joint Terrorism Task Force (JTTF) is an American locally-based multi-agency partnership between various federal, state, and local law enforcement agencies tasked with investigating terrorism and terrorism-related crimes, led by the Federal Bureau of Investigation and U.S. Department of Justice.Jerome P. BjeloperaThe Federal Bureau of Investigation and Terrorism Investigations Congressional Research Service (April 24, 2013). The first JTTFs were established in the 1980s and 1990s, with their numbers increasing dramatically after the September 11 attacks. History and organization The first JTTF was established in 1980 in New York City, with ten FBI special agents and ten New York City Police Department (NYPD) detectives. In 1999, the United States had 26 JTTFs; shortly after the attacks, FBI director Robert Mueller instructed all FBI field offices to establish formal terrorism task forces. By December 2011, there were more than 100 Joint Terrorism Task Forces nationwide, the va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
