[22], Los Rodeos airport is at 633 meters (2,077 ft) above sea level, which gives rise to cloud behavior that differs from that at many other airports. Either message, if heard in the KLM cockpit, would have alerted the crew to the situation and given them time to abort the takeoff attempt. Please Support us by turning off your adblocker. Van Zanten sees the Pan Am 747 before him, but he can do nothing other than try and get the plane airborne by pulling back on the elevators. On the Pan Am flight were a group of mostly Americans going to Gran Canaria to join a cruise. The flight engineer was the only member of the KLM's flight crew to react to the control tower's instruction to "report when runway clear"; this might have been due to him having completed his pre-flight checks, whereas his colleagues were experiencing an increased workload, just as the visibility worsened. Usually, this would be no big deal as they would continue until they saw the next turnoff. After the aircraft landed at Tenerife, the passengers were transported to the airport terminal. [4], After the KLM plane had started its takeoff roll, the tower instructed the Pan Am crew to "report when runway clear."

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. 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 Tenerife air disaster, in which a KLM 747 and a Pan Am 747 collided with a loss of 583 lives, is examined as a prototype of system vulnerability to crisis.

Exactly 40 years ago, at Tenerife-North Airport (formerly Los Rodeos), two Boeing 747s - one belonging to KLM, the other to Pan Am - collided on a foggy runway. The Pan Am aircraft had not left the runway at the third intersection. Warns had 15,210 flight hours, of which 559 hours were on the 747. Veldhuyzen van Zanten emphatically replied "Oh, yes" and continued with the takeoff.[35]. Pan Am Flight 1736 had originated at Los Angeles International Airport, with an intermediate stop at New York's John F. Kennedy International Airport (JFK). The monument was designed by Dutch sculptor Rudi van de Wint.[68]. Despite being in a hurry to leave Tenerife and get his passengers unloaded on Cran Canaria before hightailing it back to Schiphol, he had to wait for the fuel truck to finish loading the jet fuel. While waiting for the go-ahead, the flight deck can be heard fretting about strict government overtime rules and what it would mean if they were late arriving back in Amsterdam. Meanwhile, the KLM flight from Amsterdam was full of tourists planning to holiday in Gran Canaria. The Pan Am's engines were still running for a few minutes after the accident despite first officer Bragg's intention to turn them off. The true story behind the deadliest air disaster of all time ... “Report when runway clear,” the tower says to Pan Am. Let us know what you think in the comment section. It is a cyclical and logical process that lies at the base of all decision-making process, but is particularly critical when pilots make critical decisions in critical situations. The airplane operated on a flight from Tenerife-Los Rodeos International Airport (TCI) to Las Palmas-Airport de Gran Canaria (LPA). Shortly after they turned onto the runway it decreased to less than 100 m (330 ft). KLM paid the victims' families compensation ranging between $58,000 and $600,000 (or $245,000 to $2.5 million today, adjusted for inflation). 17 :06 :25 (Tenerife control tower to the PanAm 747) - Roger alpha one seven three six report when runway clear. The co-pilot who survived the Tenerife aircraft disaster Close In March 1977, two jumbo jets collided at Tenerife Airport killing 583 people. [40], Los Rodeos Airport, the only operating airport on Tenerife in 1977, was closed to all fixed-wing traffic for two days. 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. Because of that, parking area in Los Rodeos was filled with other planes, diverted from Las Palmas. Mechanistic groups typically perform very well as long as the tasks are fairly predictable and routine. She was therefore not on the KLM plane when the accident happened, and would be the only survivor of those who flew from Amsterdam to Tenerife on Flight 4805. "[36], Both airplanes were destroyed in the collision. With the fuel’s addition, the KLM jumbo was now much heavier and would need to use more of the runway to get airborne. The KLM crew then received instructions that specified the route that the aircraft was to follow after takeoff. The Pan Am crew replied: "OK, will report when we're clear." "cleared for takeoff" or "cancel takeoff clearance"). The airport was forced to accommodate a great number of large aircraft due to rerouting from the terrorist incident, resulting in disruption of the normal use of taxiways. All 248 passengers and crew aboard the KLM plane died, as did 335 passengers and crew aboard the Pan Am plane,[37] primarily due to the fire and explosions resulting from the fuel spilled and ignited in the impact.

TODAY, March 27, marks the 42nd anniversary of the deadliest incident in aviation history, also known as the Tenerife Airport Disaster. Up until that point, aircrew and controllers should use the word "departure" in its place (e.g. "[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. Eh?" [4] About 70 personnel were involved in the investigation, including representatives from the United States, the Netherlands[46] and the two airline companies. The increased severity of the fire caused by the crash led ultimately to the deaths of all those on board.
