United Airlines Flight 175 was a domestic passenger flight from Logan International Airport in Boston to Los Angeles International Airport in California that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The aircraft involved, a Boeing 767-200 carrying 65 passengers and crew, was deliberately crashed into the South Tower of the World Trade Center in New York City, killing everyone aboard and causing the deaths of more than 600 people in the South Tower's upper levels in addition to an unknown number of civilians and emergency personnel on floors beneath the impact zone. Flight 175 is the second-deadliest plane crash in aviation history, surpassed only by American Airlines Flight 11.
Philippine Airlines Flight 434, sometimes referred to as PAL434 or PR434, was a scheduled flight on December 11, 1994, from Manila to Tokyo with a quick stopover in Cebu on a Boeing 747-283B that was seriously damaged by a bomb, killing one passenger and damaging vital control systems, although the plane was in a repairable state. The incident was a test run of the unsuccessful Bojinka terrorist attacks. The Boeing 747 was flying the second leg of a route from Mactan–Cebu International Airport in Cebu, Philippines to Narita International Airport, in Tokyo, Japan. After the bomb detonated, 58-year-old veteran pilot Captain Eduardo "Ed" Reyes was able to land the aircraft, saving it and the remaining passengers and crew.
A jet bridge is an enclosed, movable connector which most commonly extends from an airport terminal gate to an airplane, and in some instances from a port to a boat or ship, allowing passengers to board and disembark without heading outside and being exposed to harsh weather. Depending on building design, sill heights, fueling positions, and operational requirements, a jet bridge may be fixed or movable, swinging radially, or extending in length. The jetway was invented by Frank Der Yuen.
Air rage is aggressive or violent behavior on the part of passengers and crew of aircraft, especially during flight. Air rage generally covers both behavior of a passenger or crew member that is likely caused by physiological or psychological stresses associated with air travel, and when a passenger or crew member becomes unruly, angry, or violent on an aircraft during a flight. Excessive consumption of alcohol is often a cause.
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all.
Business class is a travel class available on many commercial airlines and rail lines, known by brand names which vary, by airline or rail company. In the airline industry, it was originally intended as an intermediate level of service between economy class and first class, but many airlines now offer business class as the highest level of service, having eliminated first class seating. Business class is distinguished from other travel classes by the quality of seating, food, drinks, ground service and other amenities. In commercial aviation, full business class is usually denoted 'J' or 'C' with schedule flexibility, but can be many other letters depending on circumstances.
In the U.S., Federal Communications Commission (FCC) regulations prohibit the use of mobile phones aboard aircraft in flight. Contrary to popular misconception, the Federal Aviation Administration (FAA) does not actually prohibit the use of personal electronic devices on aircraft. Paragraph (b)(5) of 14 CFR 91.21 permits airlines to determine if devices can be used in flight, allowing use of "any other portable electronic device that the operator of the aircraft has determined will not cause interference with the navigation or communication system of the aircraft on which it is to be used."
Rigoberto Alpizar was a Costa Rican-born United States citizen who was fatally shot at Miami International Airport by two United States Federal Air Marshals.
A pre-flight safety briefing is a detailed explanation given before take-off to airline passengers about the safety features of the aircraft they are aboard.
Cutting in line is the act of entering a queue or line at any position other than the end. The act is frowned upon in most human cultures and stands in stark contrast to the normal policy of first come, first served that governs most queue areas.
Overselling or overbooking is sale of a volatile good or service in excess of actual supply. Overselling is a common practice in the travel and hospitality sectors, in which it is expected that some people will cancel. The practice occurs as an intentional business strategy in which sellers expect that some buyers will not consume all of the resources they are entitled to, or that some buyers will cancel. The practice of overselling aims to ensure that 100% of available supply will be used, resulting in the maximum return on investment. If more customers than the seller expects do wish to purchase or use the sold commodity, it may leave some customers lacking a service they expected to receive.
Ground support equipment (GSE) is the support equipment found at an airport, usually on the apron, the servicing area by the terminal. This equipment is used to service the aircraft between flights. As the name suggests, ground support equipment is there to support the operations of aircraft whilst on the ground. The role of this equipment generally involves ground power operations, aircraft mobility, and cargo/passenger loading operations.
An airline seat is a seat on an airliner in which passengers are accommodated for the duration of the journey. Such seats are usually arranged in rows running across the airplane's fuselage. A diagram of such seats in an aircraft is called an aircraft seat map.
Boarding is the entry of passengers onto a vehicle, usually in public transportation. Boarding starts with entering the vehicle and ends with the seating of each passenger and closing the doors. The term is used in road, rail, water and air transport.
Airport check-in is the process whereby an airline approves airplane passengers to board an airplane for a flight. Airlines typically use service counters found at airports for this process, and the check-in is normally handled by an airline itself or a handling agent working on behalf of an airline. Passengers usually hand over any baggage that they do not wish or are not allowed to carry in the aircraft's cabin and receive a boarding pass before they can proceed to board their aircraft.
An airline ticket is a document or electronic record, issued by an airline or a travel agency, that confirms that an individual is entitled to a seat on a flight on an aircraft. The airline ticket may be one of two types: a paper ticket, which comprises coupons or vouchers; and an electronic ticket.
On July 10, 1991, a L'Express Airlines Beechcraft C99, flying as Flight 508 originating in New Orleans, and in transit from Mobile to Birmingham, crashed while attempting to make an ILS approach to Runway 5 at Birmingham Municipal Airport in Birmingham, Alabama. The plane crashed in the Fairview area near Five Points West in the Ensley neighborhood and subsequently injured four persons on the ground, as well as destroying two homes. Of the 15 occupants on board, there were 13 fatalities. The cause of the crash was attributed to the captain's decision to attempt an instrument approach into severe thunderstorms resulting in a loss of control of the airplane. To date it is the deadliest commercial aviation accident in Alabama history.
American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the North Tower of the World Trade Center complex in New York City, killing everyone still alive aboard the flight and resulting in the deaths of more than one thousand people in the top 18 stories of the skyscraper in addition to causing the demise of numerous others below the trapped floors, making it not only the deadliest of the four suicide attacks executed that morning in terms of both plane and ground fatalities, but also the single deadliest act of terrorism in human history and the deadliest plane crash of all time. The aircraft involved, a Boeing 767-200(ER) with 92 passengers and crew, was flying American Airlines' daily scheduled morning transcontinental service from Boston Logan International Airport in Massachusetts to Los Angeles International Airport in California.
Jason Hyrum Steffen is an American astrophysicist and assistant professor of physics and astronomy at the University of Nevada, Las Vegas (UNLV). He is also a member of the science team for NASA's Kepler mission. He worked at Fermilab and Northwestern University for a decade before joining the UNLV faculty. He is known for his work on the discoveries of several exoplanets. He has also developed an alternative method for boarding passengers onto commercial aircraft, known as the Steffen Boarding Method. It has been found to be significantly faster than the "back-to-front" method used by most commercial airlines. He was inspired to begin research on the topic after waiting in an exceptionally long line to board a plane at an airport.
Boarding stairs, sometimes called boarding ramp or gangway in the case of ships, are devices designed to safety standards, which facilitate the access of passengers and crew to ships or on aircraft when no built-in stairs are available. Larger aircraft may use one or more fingers attached to the terminal building for passenger boarding, but boarding stairs are used when these are not available or it is impractical or too expensive to use them.
