The Boeing 707 is an early American long-range narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype first flown in 1954, the initial 707-120 first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 is a swept wing quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models.
Alaska Airlines Flight 261 was an Alaska Airlines flight of a McDonnell Douglas MD-80 series aircraft that crashed into the Pacific Ocean on January 31, 2000, roughly 2.7 miles north of Anacapa Island, California, following a catastrophic loss of pitch control, killing all 88 on board: two pilots, three flight attendants, and 83 passengers. The flight was a scheduled international passenger flight from Licenciado Gustavo Díaz Ordaz International Airport in Puerto Vallarta, Jalisco, Mexico, to Seattle–Tacoma International Airport near Seattle, Washington, United States, with an intermediate stop at San Francisco International Airport near San Francisco, California.
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw. It is part of the aircraft empennage, specifically of its stabilizers.
Aircraft upset is an unacceptable condition, in aircraft operations, in which the aircraft flight attitude or airspeed is outside the normally intended limits. This may result in the loss of control (LOC) of the aircraft, and sometimes the total loss of the aircraft itself. Loss of control may be due to excessive altitude for the airplane's weight, turbulent weather, pilot disorientation, or a system failure.
The 1977 Dan-Air/IAS Cargo Boeing 707 crash was a fatal accident involving a Boeing 707-321C cargo aircraft operated by Dan Air Services Limited on behalf of International Aviation Services Limited, which had been sub-contracted by Zambia Airways Corporation to operate a weekly scheduled all-cargo service between London Heathrow and the Zambian capital Lusaka via Athens and Nairobi. The aircraft crashed during approach to Lusaka Airport, Zambia, on 14 May 1977. All six crew members of the aircraft were killed.
China Eastern Airlines Flight 583 was a commercial passenger flight from Shanghai, China, to Los Angeles, United States, operated by China Eastern Airlines.
The 1965 Carmel mid-air collision occurred on December 4, 1965, when Eastern Air Lines Flight 853 (N6218C), a Lockheed Super Constellation en route from Boston Logan International Airport to Newark International Airport, collided in mid-air with Trans World Airlines Flight 42 (N748TW), a Boeing 707-131B en route from San Francisco International Airport to John F. Kennedy International Airport, over Carmel, New York, United States.
TWA Flight 529 was a Lockheed Constellation L-049 propliner, registration N86511, operating as a scheduled passenger service from Boston, Massachusetts to San Francisco, California. On September 1, 1961, at 02:05 CDT, the flight crashed shortly after takeoff from Midway Airport in Chicago, killing all 73 passengers and five crew on board; it was at the time the deadliest single plane disaster in U.S. history.
Northwest Orient Airlines Flight 705 was a scheduled passenger flight operated on February 12, 1963, that broke up in midair and crashed into the Florida Everglades shortly after takeoff from Miami International Airport in a severe thunderstorm. The plane was destined for Portland, Oregon, via Chicago, Spokane, and Seattle.
Provincetown-Boston Airlines Flight 1039 was a scheduled passenger flight from Jacksonville International Airport in Jacksonville, Florida, to Tampa International Airport, Florida. On December 6, 1984, the plane crashed upon takeoff at Jacksonville, killing all 13 passengers and crew.
Throughout a normal flight, a pilot controls an aircraft through the use of flight controls including maintaining straight and level flight, as well as turns, climbing, and descending. Some controls, such as a "yoke" or "stick" move and adjust the control surfaces which affects the aircraft's attitude in the three axes of pitch, roll, and yaw. Other controls include those for adjusting wing characteristics and those that control the power or thrust of the propulsion systems. The loss of primary control systems in any phase of flight is an emergency. Aircraft are not designed to be flown under such circumstances; however, some pilots faced with such an emergency have had limited success flying and landing aircraft with disabled controls.
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses.
Delta Air Lines Flight 1080 was a scheduled flight from San Diego, California to Atlanta, Georgia, notable for the incident that occurred on April 12, 1977 during the San Diego to Los Angeles leg of the flight. Unknown to the crew, the Lockheed L-1011's left elevator had become stuck in a fully upwards position. This led to the aircraft pitching up aggressively and causing the aircraft to lose speed and nearly stall. The pitching force, unable to be overcome by fully pushing the control column down, was counteracted by reducing the thrust on the L-1011's wing engines but not the tail engine. The differential thrust, along with moving all the passengers as far forwards as possible in the cabin, pitched down the nose of the airliner and allowed the pilots to land the aircraft.
Ethiopian Airlines Flight 302 was a scheduled international passenger flight from Bole International Airport in Addis Ababa, Ethiopia, to Jomo Kenyatta International Airport in Nairobi, Kenya. On 10 March 2019, the Boeing 737 MAX 8 aircraft which operated the flight crashed near the town of Bishoftu six minutes after takeoff. All 149 passengers and 8 crew members on board died.
The Maneuvering Characteristics Augmentation System (MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX in 2018 and 2019, which killed all 346 passengers and crew among both flights.
IRS Aero Flight 9601/02 was a charter flight operated by an Il-18V aircraft of the airline "IRS Aero" on the route Moscow—Khatanga—Krasnoyarsk—Khatanga—Novosibirsk—Khatanga—Moscow. On November 19, 2001, during the last leg of the route (Khatanga—Moscow), the aircraft suddenly went into a dive and crashed into the ground near Kalyazin. All 27 people on board were killed, including 18 passengers and 9 crew members.
