Eastern Daylight Time, EDT, 12 minutes after takeoff from John F. Kennedy International Airport, on a scheduled international passenger flight to Rome, with a stopover in Paris. 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] |

Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Air Lines
Eastern Air Lines, also colloquially known as Eastern, was a major United States airline from 1926 to 1991. Before its dissolution, it was headquartered at Miami International Airport in an unincorporated area of Miami-Dade County, Florida. Eastern was one of the " Big Four" domestic airlines created by the Spoils Conferences of 1930, and was headed by World War I flying ace Eddie Rickenbacker in its early years. It had a near monopoly in air travel between New York (state), New York and Florida from the 1930s until the 1950s and dominated this market for decades afterward. During airline deregulation in the late 1970s and early 1980s, labor disputes and high debt loads strained the company under the leadership of former astronaut Frank Borman. Frank Lorenzo acquired Eastern in 1985 and moved many of its assets to his other airlines, including Continental Airlines and Texas Air. After continued labor disputes and a crippling strike in 1989, Eastern ran out of money and was liq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time ... [...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 to ... [...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 electric current, current through a normally Electrical conductance, nonconductive medium such as air produces a plasma (physics), plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc. 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, Arc lamp, electric arc lighting was in wide use for Street light#Arc lamps, public lighting. Some low-pressure electric arcs are used in many applications. For example, fluorescent lamp, fluorescent tubes, mercury, sodium, and metal-halide lamps are used for lighting; xenon arc lamps have been used for movie projectors. Electric a ...

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Intelligence Agency
The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and performing covert actions. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. President Harry S. Truman had created the Central Intelligence Group under the direction of a Director of Central Intelligence by presidential directive on January 22, 1946, and this group was transformed into the Central Intelligence Agency by implementation of the National Security Act of 1947.

Joint Terrorism Task Force
In the United States, the Joint Terrorism Task Forces (JTTF) are locally-based multi-agency partnerships 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). Although JTTFs were established before the September 11, 2001 attacks, their numbers dramatically increased after the 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, prior to the attacks of September 11, 2001, 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. As of the end of December 2011, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
