Five hundred and … The investigation concluded that the fundamental cause of the accident was that captain Veldhuyzen van Zanten attempted to take off without clearance. However, a terrorist bombing there earlier in the day caused the planes to be diverted to the small Los Rodeos Airport on the island of Tenerife. [20], The angle of the third taxiway would have required the plane to perform a 148-degree turn, which would lead back toward the still-crowded main apron. [44] By March 30, a small plane shuttle service was approved, but large jets still could not land. [15] The airport had only one runway and one major taxiway running parallel to it, with four short taxiways connecting the two. This message was also blocked by the interference and inaudible to the KLM crew. According to the cockpit voice recorder (CVR), the Pan Am captain said, "There he is!" This article was most recently revised and updated by,, Smithsonian Channel - Air Disasters: Disaster at Tenerife. The KLM crew then received instructions that specified the route that the aircraft was to follow after takeoff. On March 27, 1977, shortly after 5 p.m. local time, Pan Am 1736 and KLM 4805 collided on the runway of Los Rodeos Airport in the Canary Islands. [24], Meanwhile, the KLM plane was still in good visibility, but with clouds blowing down the runway towards them.

On March 27, 1977, two Boeing 747 passenger jets, operating KLM Flight 4805 and Pan Am Flight 1736, collided on the runway at Los Rodeos Airport[1] (now Tenerife North Airport) on the Spanish island of Tenerife. About two months before the accident, he had conducted the Boeing 747 qualification check on the co-pilot of Flight 4805. After the aircraft landed at Tenerife, the passengers were transported to the airport terminal. While waiting for Gran Canaria airport to reopen, the diverted airplanes took up so much space that they were having to park on the long taxiway, making it unavailable for the purpose of taxiing. [33], A simultaneous radio call from the Pan Am crew caused mutual interference on the radio frequency, which was audible in the KLM cockpit as a 3-second-long shrill sound (or heterodyne). [6], The disaster had a lasting influence on the industry, highlighting in particular the vital importance of using standardized phraseology in radio communications. Meurs had 9,200 flight hours, of which 95 hours were on the 747. Most of the KLM passengers were Dutch; also on board were 4 Germans, 2 Austrians and 2 Americans. There were 380 passengers and crew members on board. KLM paid the victims' families compensation ranging between $58,000 and $600,000 (or $245,000 to $2.5 million today, adjusted for inflation). A tour guide had chosen not to reboard for the flight to Las Palmas, because she lived on Tenerife and thought it impractical to fly to Gran Canaria only to return to Tenerife the next day. Slaton was dispatched from Torrejon Air Base just outside of Madrid, Spain. [6] The sum of settlements for property and damages was $110 million (or $464 million today),[51] an average of $189,000 (or $797,000 today) per victim, due to limitations imposed by European Compensation Conventions in effect at the time.

[13] There had been a phone call warning of the bomb, and another call received soon afterwards made claims of a second bomb at the airport. The control tower and the crews of both planes were unable to see one another. Shortly after they turned onto the runway it decreased to less than 100 m (330 ft). 27, 1977. The Pan Am crew appeared to remain unsure of their position on the runway until the collision, which occurred near the intersection with the fourth taxiway (C-4). Had the plane turned at the third exit as instructed, the collision would not have occurred. 27 mars 1977 : Une collision aérienne à Ténérife (Espagne, îles Canaries) entre deux Boeing 747, cause 583 morts. "[21] The official report from the Spanish authorities explains that the controller instructed the Pan Am aircraft to use the third taxiway because this was the earliest exit that they could take to reach the unobstructed section of the parallel taxiway. The transmission from the tower in which the controller passed KLM their ATC clearance was ambiguous and could have been interpreted as also giving take-off clearance. The accident was investigated by Spain's Comisión de Investigación de Accidentes e Incidentes de Aviación Civil (CIAIAC). Get off!" In desperation, the pilots prematurely rotated the aircraft and attempted to clear the Pan Am by lifting off, causing a 22 m (72 ft) tailstrike. [52] These included: The extra fuel taken on by the KLM added several factors: As a consequence of the accident, sweeping changes were made to international airline regulations and to aircraft. Both islands are part of the Canary Islands, an autonomous community of Spain located in the Atlantic Ocean off the southwest coast of Morocco. Crash at Tenerife, Canary Islands. Two jumbo jets collide in the Tenerife airport disaster, killing at least 560 people. In 1977, a cross in Rancho Bernardo was dedicated to nineteen area residents who died during the disaster. The plane immediately went into a stall, rolled sharply, and hit the ground approximately 150 m (500 ft) past the collision, sliding down the runway for a further 300 m (1,000 ft). J'ai fait un petit montage sur les 9 causes qui ont provoqué le crash à Ténérife le 27 mars 1977. Both planes involved in the crash had been scheduled to depart from Las Palmas on the island of Gran Canaria. indicated that captain Grubbs and first officer Bragg had recognized the ambiguity (this message was not audible to the control tower or KLM crew due to simultaneous cross-communication); The Pan Am had taxied beyond the third exit. Just 61 people survived, all from the Pan Am jumbo jet. The International Tenerife Memorial March 27, 1977, was inaugurated at the Mesa Mota on March 27, 2007. Crash-aerien 27 MAR 1977 d'un Boeing 747-121 N736PA - Tenerife-Los Rodeos International Airport (TCI) A Boeing 747-121 passenger plane, registered N736PA, was destroyed in an accident at Tenerife-Los Rodeos International Airport (TCI), Spain. Warns had 15,210 flight hours, of which 559 hours were on the 747. The first crash investigators to arrive at Tenerife the day after the crash travelled there by way of a three-hour boat ride from Las Palmas. The ALPA study group concluded that the KLM crew did not realize that the transmission "Papa Alpha one seven three six, report when runway clear" was directed at the Pan Am, because this was the first and only time the Pan Am was referred to by that name. When it became clear that the KLM aircraft was approaching at takeoff speed, Captain Grubbs exclaimed, "Goddamn, that son-of-a-bitch is coming! The Pan Am crew's transmission was "We're still taxiing down the runway, the Clipper 1736!" The impact and resulting fire killed everyone on board KLM 4805 and most of the occupants of Pan Am 1736, with only 61 survivors in the front section of the aircraft. ): Type: Collision (Une collision est un choc direct entre deux objets.

[66][67], In 2007, the 30th anniversary marked the first time that Dutch and American next-of-kin and aid helpers from Tenerife joined an international commemoration service, held at the Auditorio de Tenerife in Santa Cruz. The controller's response of "OK" to the co-pilot's nonstandard statement that they were "now at takeoff" was likely due to his misinterpretation that they were in takeoff position and ready to begin the roll when takeoff clearance was received, but not in the process of taking off. Many survivors escaped from a hole near the plane’s left wing. 17 :06 :47 (commandant KLM) – Oh merde [12], Both flights had been routine until they approached the islands. [4] About 70 personnel were involved in the investigation, including representatives from the United States, the Netherlands[46] and the two airline companies. It remains the worlds deadliest air disaster. The tower instructed the KLM to taxi down the entire length of the runway and then make a 180-degree turn to get into takeoff position. Its nose landing gear cleared the Pan Am, but its left-side engines, lower fuselage, and main landing gear struck the upper right side of the Pan Am's fuselage,[10] ripping apart the center of the Pan Am jet almost directly above the wing. The aircraft was a Boeing 747-121, registration N736PA, named Clipper Victor. 583 personnes ont péri dans la collision la plus meurtrière de l’aviation civile, le 27 mars 1977, entre deux Boeing 747 sur l’aéroport de Tenerife aux Canaries.

This particular aircraft had operated the inaugural 747 commercial flight on January 22, 1970. [41] The first aircraft that was able to land was a United States Air Force C-130 transport, which landed on the airport's main taxiway at 12:50 on March 29. [18], The crew successfully identified the first two taxiways (C-1 and C-2), but their discussion in the cockpit never indicated that they had sighted the third taxiway (C-3), which they had been instructed to use. At the end of C-3, the Pan Am would have to make another 148-degree turn, in order to continue taxiing towards the start of the runway, similar to a mirrored letter "Z". 27 mars 1977 - L'accident le plus dramatique de l'histoire de l'aviation.

This caused the KLM crew to miss the crucial latter portion of the tower's response. The Pan Am plane was ready to depart from Tenerife, but access to the runway was being obstructed by the KLM plane and a refueling vehicle; the KLM captain had decided to fully refuel at Los Rodeos instead of Las Palmas, apparently to save time. Collision on Tenerife is many things: a detailed post-mortem of what, exactly, went wrong; an agonizing narrative of how hundreds of people managed to survive the terrible ordeal; and a striking lesson in what to do, and not do, in the event of a disaster. Hierarchical relations among crew members were played down, and greater emphasis was placed on team decision-making by mutual agreement. Le 27 mars 1977, une catastrophe aérienne avait causé la mort de 583 personnes sur l'aéroport de Los Rodeos, au nord de l'île de Tenerife, aux Canaries. Instead, departing aircraft needed to taxi along the runway to position themselves for takeoff, a procedure known as a backtaxi or backtrack.[4]. The KLM plane remained briefly airborne, but the impact had sheared off the outer left engine, caused significant amounts of shredded materials to be ingested by the inner left engine, and damaged the wings. [23], The Pan Am crew found themselves in poor and rapidly deteriorating visibility almost as soon as they entered the runway. (Originally published by the Daily News on March 28, 1977.) All passengers and crew members aboard the KLM plane were killed. and "We are still taxiing down the runway, the Clipper 1736!" [19] There were no markings or signs to identify the runway exits and they were in conditions of poor visibility. [44] Los Rodeos was fully reopened on April 3, after wreckage had been fully removed and engineers had repaired the airport's runway.[45]. Pour l’anecdote ma novia (fiancée ou « petite-amie » en français) habitait et habite toujours à Los Rodeos, un faubourg de San Cristobal de la Laguna. L’accident eut lieu il y a 40 ans, au milieu du calme après-midi de ce dimanche 27 mars 1977. Resulting in 583 fatalities, this accident is the deadliest in aviation history. She was therefore not on the KLM plane when the accident happened, and she would be the only survivor of those who flew from Amsterdam to Tenerife on Flight 4805. Patches of thick fog were drifting across the airfield, hence visibility was greatly reduced for pilots and the control tower. Omissions? A study carried out by the Air Line Pilots Association (ALPA) after the accident concluded that making the second 148-degree turn at the end of taxiway C-3 would have been "a practical impossibility. The collision took place in a high-density cloud. [2][3] Resulting in 583 fatalities, this accident is the deadliest in aviation history. "The magnitude of the accident speaks for itself, but what makes it particularly unforgettable is the startling set of ironies and coincidences that preceded it. "Collision on Tenerife: The How and Why of the World's Worst Aviation Disaster," by Jon Ziomek (Post Hill Press, 2018).

There is also a memorial at the Westminster Memorial Park and Mortuary in Westminster, California. Taxiway C-4 would have required two 35-degree-turns. Drifting clouds of different densities cause wildly varying visibilities, from unhindered at one moment to below the minimums the next. The controller then immediately added "stand by for takeoff, I will call you",[4] indicating that he had not intended the instruction to be interpreted as a takeoff clearance. [2][3], The collision occurred when the KLM airliner initiated its takeoff run while the Pan Am airliner, shrouded in fog, was still on the runway and about to turn off onto the taxiway. [48] The Netherlands Department of Civil Aviation published a response that, while accepting that the KLM captain had taken off "prematurely", argued that he alone should not be blamed for the "mutual misunderstanding" that occurred between the controller and the KLM crew, and that limitations of using radio as a means of communication should have been given greater consideration. 1977: Two Boeing 747s collide on a fog-shrouded runway at Tenerife in the Canary Islands, killing 583 people in the worst accident in aviation history. According to the ALPA report, as the Pan Am aircraft taxied to the runway, the visibility was about 500 m (1,600 ft). By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Interference from simultaneous radio transmissions, with the result that it was difficult to hear the message. The apparent hesitation of the flight engineer and the first officer to challenge Veldhuyzen van Zanten further. The KLM 747 was within 100 m (330 ft) of the Pan Am and moving at approximately 140 knots (260 km/h; 160 mph) when it left the ground. [42][43], Spanish Army soldiers were tasked with clearing crash wreckage from the runways and taxiways. Most of the survivors on the Pan Am walked out onto the intact left wing, the side away from the collision, through holes in the fuselage structure. The crew asked for clarification and the controller responded emphatically by replying: "The third one, sir; one, two, three; third, third one." Less experienced flight crew members were encouraged to challenge their captains when they believed something to be incorrect, and captains were instructed to listen to their crew and evaluate all decisions in light of crew concerns. [citation needed] Facts showed that there had been misinterpretations and false assumptions before the accident. Other major factors contributing to the accident were: The following factors were considered contributing but not critical: The Dutch authorities were reluctant to accept the Spanish report blaming the KLM captain for the accident. The word "takeoff" is now spoken only when the actual takeoff clearance is given, or when cancelling that same clearance (i.e. Let us know if you have suggestions to improve this article (requires login). Los Rodeos, renamed Tenerife North Airport (TFN), was then used only for domestic and inter-island flights until 2002, when a new terminal was opened and Tenerife North began to carry international traffic again. The force from the crash tore through the fuselage of the Pan Am plane, and both aircraft exploded into flames. aviation disaster, Tenerife, Canary Islands [1977]. Up until that point, aircrew and controllers should use the word "departure" in its place (e.g. These include the Survival in the Sky episode "Blaming the Pilot", the Seconds From Disaster episode "Collision on the Runway", PBS's NOVA episode "The Deadliest Plane Crash" in 2006, the PBS special Surviving Disaster: How the Brain Works Under Extreme Duress (based on Amanda Ripley's book The Unthinkable: Who Survives When Disaster Strikes - and Why) in 2011, Destroyed in Seconds and an episode of the Canadian TV series Mayday (known by different names in different countries), namely the season 16 standard length episode "Disaster at Tenerife" with the earlier more in-depth 90-minute "Crash of the Century" being a spin-off. Veldhuyzen van Zanten emphatically replied "Oh, yes" and continued with the takeoff.[35]. [8] Its cockpit crew consisted of Captain Jacob Veldhuyzen van Zanten (age 50),[9] First Officer Klaas Meurs (42), and Flight Engineer Willem Schreuder (48). On hearing this, the KLM flight engineer expressed his concern about the Pan Am not being clear of the runway by asking the pilots in his own cockpit, "Is he not clear, that Pan American?" The Pan Am aircraft had not left the runway at the third intersection. The official investigation suggested that this might have been due not only to the captain's seniority in rank, but also to his being one of the most respected pilots working for the airline. "ready for departure"). 27 mars 1977 : terrible collision à Tenerife. The KLM jet was carrying 14 crew members and 235 passengers, including 52 children. The aircraft completed its 180-degree turn in relatively clear weather and lined up on Runway 30. Additionally, an ATC clearance given to an aircraft already lined-up on the runway must be prefixed with the instruction "hold position". [40], Los Rodeos Airport, the only operating airport on Tenerife in 1977, was closed to all fixed-wing traffic for two days. It was the worst crash in aviation history. A Dutch national memorial and final resting place for the victims of the KLM plane is located in Amsterdam, at Westgaarde cemetery. The authorities reopened Gran Canaria airport once the bomb threat had been contained. [16] While the KLM was backtaxiing on the runway, the controller asked the flight crew to report when it was ready to copy the ATC clearance. At least 330 people on the Pan Am plane died, but more than 60, including the pilot, survived the impact and fire. Meurs then radioed the tower that they were "ready for takeoff" and "waiting for our ATC clearance". The Tenerife Airport Disaster occurred at just before 5:07pm on 27 March 1977. [8] On August 2, 1970, in its first year of service, it also became the first 747 to be hijacked: en route between JFK and Luis Muñoz Marín International Airport in San Juan, Puerto Rico, it was diverted to José Martí International Airport in Havana, Cuba. Dans les années 1970, le transport aérien se démocratise et les avions deviennent de plus en plus gros. In March 1977, two jumbo jets collided at Tenerife Airport killing 583 people. La catastrophe de Ténérife - 27 mars 1977. This course of action was later expanded into what is known today as crew resource management (CRM), training which is now mandatory for all airline pilots.[63][64]. "[4], The controller, who could not see the runway due to the fog, initially responded with "OK" (terminology that is nonstandard), which reinforced the KLM captain's misinterpretation that they had takeoff clearance. "[4] Captain Veldhuyzen van Zanten interrupted the co-pilot's read-back with the comment, "We're going. The full load of fuel, which had caused the earlier delay, ignited immediately into a fireball that could not be subdued for several hours. The crowded airport had placed additional pressure on all parties, including the KLM cockpit crew, the Pan Am cockpit crew, and the controller; Sounds on the CVR suggested that during the accident the Spanish control tower crew had been listening to a. [62], Cockpit procedures were also changed after the accident. A terrorist incident at Gran Canaria Airport had caused many flights to be diverted to Los Rodeos, including the two aircraft involved in the accident. At the time of the accident, Veldhuyzen van Zanten was KLM's chief flight instructor, with 11,700 flight hours, of which 1,545 hours were on the 747. 583 died, the worst commercial aviation disaster in history. Alors que l' aéroport est plongé dans le brouillard, un 747-200 de la KLM entame son décollage et percute un 747-100 de la Pan Am qui est en train de remonter la piste . L’un de KLM, l’autre de la Pan Am s’apprêtent à rejoindre l'aéroport espagnol de Las Palmas.

On March 27, 1977, two 747 jumbo jets crash into each other on the runway at an airport in the Canary Islands, killing 582 passengers and crew members. DANS LE RETRO – Il y a 42 ans, le 27 mars 1977, deux Boeing 747 entraient en collision sur l’aéroport de Tenerife-Nord aux Canaries. In particular, the Dutch response pointed out that: Although the Dutch authorities were initially reluctant to blame captain Veldhuyzen van Zanten and his crew,[5][50] the airline ultimately accepted responsibility for the accident. The right-side engines crashed through the Pan Am's upper deck immediately behind the cockpit. Tenerife airline disaster, runway collision of two Boeing 747 passenger airplanes in the Canary Islands on March 27, 1977, that killed more than 580 people. [4] Dutch investigators placed a greater emphasis on mutual misunderstanding in radio communications between the KLM crew and ATC,[5] but ultimately KLM admitted that their crew was responsible for the accident and the airline agreed to financially compensate the relatives of all of the victims. Survivors waited for rescue, but it did not come promptly, as the firefighters were initially unaware that there were two aircraft involved and were concentrating on the KLM wreck hundreds of meters away in the thick fog and smoke.
