Indian Airlines Flight 423 was hijacked by five Sikh militants of the Dal Khalsa organization while en route from Delhi to Amritsar. The hijackers, armed with daggers and a hand grenade, forced the Boeing 737 to land at Lahore Airport in Pakistan. They demanded the release of militant leader Jarnail Singh Bhindranwale and 500,000 USD in cash. Following a request from the Indian government, Pakistani Special Service Group (SSG) commandos stormed the aircraft on September 30, 1981, successfully apprehending the hijackers and releasing all 111 passengers and 6 crew members without fatalities.

Security / Sabotage

Eastern Air Lines Flight 935 suffered a catastrophic uncontained failure of its number 2 (tail-mounted) engine while climbing through 10,000 feet. The failure severed three of the aircraft's four independent hydraulic systems, leaving the crew with severely degraded flight controls. Despite the loss of systems A, B, and D, the pilots successfully performed an emergency landing at John F. Kennedy International Airport using the remaining hydraulic system, differential engine thrust, and limited flight control surfaces. All 201 occupants survived without injury.

Engine Failure

Aeropesca Colombia Flight 221, operated by a Vickers Viscount 745D, crashed into Mount Matiqui while en route from Florencia to Neiva. The aircraft struck the mountain at an elevation of approximately 9,000 feet, resulting in the deaths of all 50 people on board. The investigation determined that the flight crew continued to operate under Visual Flight Rules (VFR) despite encountering meteorological conditions that were below the legal minimums for the route.

Controlled Flight Into Terrain (CFIT)

Aeroflot Flight 811, an Antonov An-24RV, collided mid-air with a Soviet Air Force Tupolev Tu-16K strategic bomber at an altitude of 5,220 meters. The collision occurred due to poor coordination between military and civilian air traffic controllers and a failure by the military flight director to use radar to track the bombers. Both aircraft disintegrated, but one passenger, Larisa Savitskaya, survived a 5.2-kilometer fall inside a fragment of the An-24's fuselage that glided into a swampy glade. The Soviet government suppressed news of the accident for two decades, initially claiming Savitskaya had crashed in a homemade glider.

Mid-air Collision · Multi-aircraft

A Westland Wessex 60 helicopter plunged into the North Sea after the pilot reported an engine failure while returning from the Leman gas field. The aircraft was operating a routine passenger and freight flight that served the Leman and Indefatigable gas fields. At 15:41, while en route to the Bacton gas terminal, the commander transmitted a distress message stating he was ditching due to engine failure, and radar contact was lost three seconds later. Search and rescue teams located floating wreckage within 16 minutes, but there were no survivors among the 11 passengers and 2 crew members. Due to delays in salvage operations, the wreckage became unrecoverable, leaving investigators with insufficient evidence to determine the exact cause of the power loss or subsequent loss of control.

Unknown

A Panamanian Air Force DHC-6 Twin Otter carrying General Omar Torrijos, the military leader of Panama, crashed into Marta Hill during a flight to Coclesito. The aircraft struck the mountain at approximately 3,100 feet above sea level while the pilots were attempting to navigate through heavy fog and low visibility. All seven occupants were killed. The accident occurred in a region with limited radar coverage, and the wreckage was not located for nearly 24 hours, eventually being discovered with assistance from the United States military.

Controlled Flight Into Terrain (CFIT)

Aeroméxico Flight 230 crashed during a landing attempt in severe weather at Chihuahua International Airport, resulting in 32 fatalities. The aircraft encountered isolated cumulonimbus clouds, strong squalls, and heavy showers that significantly reduced visibility during the final approach. Upon touchdown, the DC-9 bounced and struck the ground with sufficient force to cause a structural failure, leading to a runway excursion and a subsequent intense fire. While 34 occupants managed to escape the wreckage, those remaining trapped succumbed to smoke inhalation and fire.

Weather

Somali Airlines Flight 40 crashed shortly after takeoff from Mogadishu when it encountered severe turbulence and heavy rain. The aircraft entered a high-speed spiral dive that generated aerodynamic loads far exceeding its design limits, resulting in the structural failure and separation of the right wing.

Weather

A Canadair CL-44 cargo aircraft operated by Transporte Aéreo Rioplatense was intercepted and downed by a Soviet Sukhoi Su-15 fighter after straying into Soviet airspace. The aircraft was returning to Cyprus from Tehran as part of a secret arms airlift between Israel and Iran; the flight path via Larnaca was intended to disguise the Israeli arms cargo as civilian goods like fruit or pharmaceuticals. Soviet authorities claimed the crew ignored radio calls and visual signals, leading the Su-15 pilot to perform a deliberate ramming maneuver (taran) to stop the intrusion. All four occupants of the CL-44 were killed, while the Soviet pilot successfully ejected.

Mid-air Collision

A Hawker Siddeley HS 748-108 series 2A cargo aircraft, operating a mail flight, suffered a catastrophic in-flight structural failure after the rear baggage door opened and detached during descent. The door became lodged on the leading edge of the right horizontal tailplane, causing severe aerodynamic instability and pitch oscillations. The resulting aerodynamic loads exceeded the aircraft's structural limits, causing both wings and the tailplane to separate from the fuselage. All three people on board—two pilots and one cabin attendant serving as a postal assistant—were killed.

Mechanical Failure

Aeroflot Flight 498 crashed into a mountain on the Holy Nose Peninsula while attempting to divert to Ust-Barguzin due to poor weather at its scheduled stopover. The crew, navigating with unstable direction-finding equipment, became significantly off-course and falsely reported having the airfield in sight to the Ulan-Ude controller, whom they had contacted in violation of procedures instead of maintaining contact with the Ust-Barguzin tower. Mistaking the peninsula's terrain for the airfield's location in low visibility, the pilots descended into the mountainside, killing all 48 people on board.

Controlled Flight Into Terrain (CFIT)

Austral Líneas Aéreas Flight 901 crashed into the Río de la Plata after the crew lost control while attempting to navigate through an extremely violent thunderstorm. Following a missed approach at Aeroparque Jorge Newbery due to poor visibility and heavy rain, the aircraft was directed to a holding pattern. While attempting to return for a second approach, the pilot flew directly into a cumulonimbus cell. The investigation, hampered by the failure to recover the flight recorders, attributed the crash to the pilot's error in evaluating the severity of the meteorological conditions.

Pilot Error

Aer Lingus Flight 164, carrying 103 passengers and 5 crew, was hijacked by Laurence James Downey, a former Trappist monk, during its approach to London Heathrow. Downey doused himself in petrol and demanded to be flown to Tehran, Iran, to deliver a new constitution. Due to fuel limitations, the aircraft diverted to Le Touquet, France, where an eight-hour standoff ensued. The hijacker eventually demanded the publication of a nine-page manifesto regarding the Third Secret of Fatima. French special forces (GIGN) stormed the aircraft and apprehended Downey without injury to any passengers or crew.

Security / Sabotage

An Ilyushin Il-14 crashed during a landing attempt at the Ernst Krenkel Observatory on Heiss Island after the pilot failed to abort the approach despite losing visual contact with the runway lights. The aircraft was operating a special flight carrying meteorological scientists and equipment from Moscow. During the final approach in polar twilight and poor visibility, the aircraft touched down in deep, unpacked snow 32 meters to the left of the runway. The resulting collapse of the nose gear and impact caused cargo and a fuel tank to shift forward into the cabin, killing two passengers.

Pilot Error

A Soviet Navy Tupolev Tu-104A crashed seconds after takeoff from Pushkin Airport, killing all 50 people on board, including 16 high-ranking admirals and generals of the Pacific Fleet. The accident was caused by a massive shift in the center of gravity due to improperly secured cargo and passengers sitting in unassigned areas, leading to an unrecoverable pitch-up and stall.

Human Factors (Operational)

A Lockheed L-1011 TriStar suffered an explosive decompression at 29,000 feet after a main landing gear wheel flange failed, causing a tire to burst. The resulting explosion tore a hole in the fuselage and cabin floor, through which two children were ejected and killed. The flight crew successfully performed an emergency descent and landed the aircraft in Doha, Qatar.

Mechanical Failure

A Cessna 421A carrying Portuguese Prime Minister Francisco de Sá Carneiro, his partner Snu Abecassis, Defense Minister Adelino Amaro da Costa, and his wife Maria Manuel Pires crashed into a residential neighborhood in Camarate shortly after takeoff from Lisbon. The aircraft struck high-voltage power lines and erupted in a fireball, killing all seven people on board, including Chief of Cabinet Patrício Gouveia and two pilots. While the initial official investigation and a 2002 commission attributed the crash to an accident involving fuel exhaustion, weight issues, and pilot error, a 2004 parliamentary inquiry concluded that an explosive device had been placed on the aircraft. The case remains a major political controversy, characterized by a long-standing dispute between judicial findings of an accident and parliamentary conclusions of an assassination.

Other

Air Micronesia Flight 614, operated by Continental Airlines, crashed short of the runway at Yap Airport during a landing attempt. The aircraft touched down 13 feet short of the threshold on upward-sloping terrain, causing the right main landing gear to separate. The Boeing 727 veered off the runway and came to rest in the jungle, where a severe fire destroyed the airframe. Despite the destruction of the aircraft, all 73 occupants successfully evacuated within one minute, with only three individuals sustaining serious injuries.

Pilot Error

A Latin Carga Convair CV-880 cargo jet crashed during takeoff from Caracas-Simón Bolívar International Airport during a crew training flight. All four occupants on board were killed when the aircraft was destroyed upon impact. The flight was intended as a local training sortie, but the aircraft failed to maintain flight shortly after lifting off, coming to rest near the airport perimeter.

Unknown

A Douglas A-26 Invader warbird, nicknamed Double Trouble, crashed during the Battle of Britain airshow at Biggin Hill while performing an aerobatic maneuver. The aircraft was conducting a fast run along the crowd line at 150 feet before attempting a barrel roll or wingover. During the maneuver, the aircraft became inverted, the roll rate increased, and the bomber dived into a valley at the end of the runway. All seven occupants, including six passengers, were killed. At the time, regulations did not strictly prohibit carrying passengers during air displays, a fact that changed as a direct result of this accident.

Pilot Error

Florida Commuter Airlines Flight 65, a Douglas DC-3A, crashed into the Atlantic Ocean during a night approach to Freeport, Bahamas, in heavy thunderstorm activity. All 34 people on board were killed. The investigation was severely hampered by the inability to recover the wreckage from the deep ocean floor and the lack of flight recorders. While the NTSB could not determine a definitive cause, they highlighted improper maintenance of the pitot-static system, flight into known severe weather, and poor operational management as significant contributing factors.
