Delta Air Lines Flight 89
Delta Air Lines Flight 89 was a scheduled flight from Los Angeles International Airport (LAX) to Shanghai Pudong International Airport (PVG). On January 14, 2020, the Boeing 777-200ER conducting the flight had engine problems shortly after takeoff; while returning to the origin airport for an emergency landing, it dumped fuel over populated areas adjacent to the city of Los Angeles, resulting in skin and lung irritation in at least 56 people on the ground and triggering a Federal Aviation Administration (FAA) investigation. The aircraft landed safely with no injuries to passengers or crew. Background Flight 89 was a regularly scheduled Delta Air Lines flight from LAX to Shanghai Pudong International Airport. On January 14, 2020, the Boeing 777-200ER widebody jet aircraft operating as Flight 89 departed from LAX at 11:32a.m. The aircraft had 149 passengers and 16 crew members on board. To reach Shanghai, the aircraft would be carrying enough fuel to exceed its certified max ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressor Stall
A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop barely registered by the engine instruments to a complete loss of compression in case of a surge, requiring adjustments in the fuel flow to recover normal operation. Compressor stall was a common problem on early jet engines with simple aerodynamics and manual or mechanical fuel control units, but has been virtually eliminated by better design and the use of hydromechanical and electronic control systems such as Full Authority Digital Engine Control. Modern compressors are carefully designed and controlled to avoid or limit stall within an engine's operating range. Types There are two types of compressor stall: Rotating stall Rotating stall is a local disruption of airflow within the com ...

The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergate scandal ...

The Bakersfield Californian
''The Bakersfield Californian'' is a daily newspaper serving Bakersfield, California and surrounding Kern County in the state's San Joaquin Valley. History ''The Bakersfield Californian'' is the direct descendant of Kern County's first newspaper, ''The Weekly Courier'', which was first published on Aug. 18, 1866, in Havilah, California. At that time, Havilah, a small mining town about 50 miles northeast of the present site of Bakersfield, was the center of the 1864 gold rush, which brought the first major population influx to Kern County. The newspaper's name was later changed to ''The Havilah Weekly Courier''. As the mineral wealth of the area became depleted and the population moved southward toward Bakersfield, the newspaper also moved to Bakersfield in 1872, becoming ''The Kern County Weekly Courier''. In 1876, the ''Courier'' merged with another Bakersfield newspaper, ''The Southern Californian'', to form ''The Kern County Californian''. Its name was changed to ''The Daily ...

Physical Education
Physical education, often abbreviated to Phys Ed. or P.E., is a subject taught in schools around the world. It is usually taught during primary and secondary education, and encourages psychomotor learning by using a play and movement exploration setting to promote health and physical fitness. Activities in P.E. include football, netball, hockey, rounders, cricket, four square, racing, and numerous other children's games. Physical education also teaches nutrition, healthy habits, and individuality of needs. Physical education programs vary all over the world. When taught correctly, P.E. class can produce positive effects on students' health, behavior, and academic performance. As part of this, health education is the teaching of information on the prevention, control, and treatment of diseases. It is taught with physical education, or P.H.E. for short.

Jet Fuel
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point. Kerosene-type jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
