Mayday

On June 1, 1999, American Airlines Flight 1420 tries to land at the Little Rock National Airport during a storm, but overruns the runway, killing eleven people.

On June 10, 1990, the cockpit window blows out on British Airways Flight 5390, partially ejecting and injuring the captain through the hole. A member of the cabin crew clings to his legs as the co-pilot completes an emergency landing without any fatality. The captain is found to be still alive after being outside the cockpit for 21 minutes.

On 28 April 1988, Aloha Airlines Flight 243 is en route from Hilo to Honolulu in Hawaii, when the upper half of the front fuselage is torn off, blowing out a flight attendant. The aircraft subsequently lands safely at Kahului, Maui. The fuselage failed from corrosion damage and metal fatigue.

On 2 August 2005, Air France Flight 358 overruns the runway while attempting to land in a storm. The Airbus A340 travels through the airport perimeter fence into a small ravine and catches fire. The causes of the crash were the aircraft deviating above the required approach path for its landing, touching down too far along the runway and the crew deploying the thrust reversers too slowly. All 309 passengers and crew survived. Alternate title: "Desperate Escape"

On 23 June 1985, Air India Flight 182 explodes in mid-air and disintegrates over the coast of Ireland, killing all 329 passengers and crew members on board. Investigators discovered that a bomb from Sikh militant group Babbar Khalsa caused the explosion.

BOAC Flight 781 ,South African Airways Flight 201, Aloha Airlines Flight 243, British Airways Flight 5390, United Airlines Flight 811, Helios Airways Flight 522. This special looks at accidents and incidents where pressurization failure or explosive decompression played a part. Episodes re-visited: Hanging by a Thread, Blow Out, Unlocking Disaster, Ghost Plane.

Shortly after leaving London Heathrow airport in December 1988, Pan Am flight 103 exploded above Lockerbie , Scotland killing 270 people. Investigators soon discovered that a bomb in the forward cargo compartment had taken down the plane.

1956 Grand Canyon mid-air collision, 1986 Cerritos mid-air collision, Avianca Flight 52, Gol Transportes Aéreos Flight 1907, Überlingen mid-air collision. This special looked at the role of air traffic controllers in the airline industry, and took a look at the Next Generation Air Transportation System, a new technology meant to eliminate mid-air collisions by reducing overall dependence on radar and radio, as well as delegating some of the air traffic controllers' tasks to computers on board each plane.

On 22 August 1985, an engine of British Airtours Flight 28M fails during takeoff, puncturing a hole in the wing fuel tank and starting a fire. The crew successfully abandons the takeoff and stops the aircraft on the runway, but the fire spreads to the cabin. 55 people die before they can evacuate, mainly due to inhaling toxic smoke. The investigation found that fatigue of a part in the engine caused it to fail.

On 25 February 2009, Turkish Airlines Flight 1951 is on approach to land at Schiphol in Amsterdam, when it stalls and crashes 1.5 kilometres from the runway. Nine people, including the three cockpit crew members, are killed. A faulty radar altimeter caused the aircraft's flight control computer to automatically reduce engine thrust prematurely, and the flight crew failed to notice the resulting drop in airspeed until it was too late.

On 17 July 2007, TAM Airlines Flight 3054 careens off runway 35L at Brazil's Congonhas Airport, crashes at high speed into a warehouse adjacent to a filling station and explodes. A total of 199 people on board the aircraft and on the ground are killed. Incorrect engine throttle settings upon landing caused one engine to reverse thrust while the other increased power, resulting in the loss of control.

On 8 June 1983, Reeve Aleutian Airways Flight 8's propeller separates from the aircraft over Cold Bay, Alaska, causing an explosive decompression and loss of control. The pilots manage to land the aircraft safely at Anchorage, Alaska. The propeller fell into the sea, and the cause of the separation is undetermined.

On 18 June 1972, British European Airways Flight 548 stalls and crashes in a field near Staines-upon-Thames shortly after takeoff from London Heathrow Airport, killing all 118 people on board. The crash was attributed to the pilot retracting the aircraft's droops at too low an airspeed and failing to recognise the stall warnings.

On 8 January 1989, British Midland Flight 92 crashes onto the embankment of the M1 motorway near Kegworth, Leicestershire, UK. The aircraft was attempting to conduct an emergency landing at East Midlands Airport. Of the 126 people aboard, 47 died and 74, including seven members of the flight crew, sustained serious injuries.

On 19 November 1996, United Express Flight 5925, operating for Great Lakes Airlines, lands at Quincy Regional Airport and collides with a light aircraft taking off from an intersecting runway. All 14 occupants on both aircraft were killed in a subsequent fire.

On 25 October 1999, a chartered Learjet 35 operated by Sunjet Aviation, carrying golfer Payne Stewart and his agents, runs out of fuel and crashes into a field in South Dakota after flying off course, killing all 6 occupants on board.

After a routine one-hour flight from Minneapolis, Northwest Airlink Flight 5719 crashes in northern Minnesota, killing everyone on board. Investigators face intense pressure to find the cause. The cockpit voice recorder raises disturbing questions about an inexperienced pilot. But as investigators dig deeper, they uncover a troubling pattern of abuse that led to a breakdown in human cooperation.

On 16 February 2000, Emery Worldwide Flight 17 crashes into an automobile salvage yard shortly after taking off from Sacramento Mather Airport on a flight to Dayton, Ohio, killing all 3 crew members on board.

En route to Hong Kong, Cathay Pacific Flight 780 is high over the South China Sea when both of the plane's engines fail, turning the Airbus A-330 into a 200-ton glider; the captain takes over manual control and manages to power up one engine.

(Uni Air Flight 873) Experts fail to find a bomb when a Taiwanese plane explodes. But as they examine the wreckage, they uncover something shocking in the overhead lockers.

On 15 December 2014, Loganair Flight 6780 starts an uncontrolled descent while on approach to Sumburgh Airport in Scotland. The pilots regain control and make an emergency landing at Aberdeen, with no fatalities. A lightning strike had disabled the aircraft's elevator controls.

When Alaska Airlines Flight 261 suddenly nosedives into the Pacific, investigators uncover a critical maintenance issue with deadly implications.

Corporate Airlines Flight 5966 appears out of the clouds and crashes into trees on approach to Kirksville, Missouri. The twin-engine turboprop plane catches fire just over a kilometer from the runway. The charred wreckage offers clues as to what happened. The researchers conclude that it was not a mechanical failure. They hear a recording from the cockpit that may reveal the whole beginning of the accident.

A massive explosion tears a hole in a 747 over Hawaii, and the trail of clues ultimately leads investigators to a catastrophic short circuit.

The pilots of a crashed cargo jet believe they lost both engines. But when the wreckage emerges from the Pacific, the evidence tells another story.
