The Tenerife Airport Accident ( LOS RODEOS AIRPORT INCIDENT)

Instructions

(this has sound effects in it. but they are not real.) they are ported from other planes taking off / taxing. the plane crash sound is not real. The Tenerife airport disaster occurred on March 27, 1977, when two Boeing 747 passenger jets collided on the runway at Los Rodeos Airport[1] (now Tenerife North Airport) on the Spanish island of Tenerife.[2][3] The collision occurred when KLM Flight 4805 initiated its takeoff run while Pan Am Flight 1736 was still on the runway. 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.[2][3] With 583 fatalities, the disaster is the deadliest accident in aviation history. A bomb set off by the Canary Islands Independence Movement at Gran Canaria Airport had caused many flights to be diverted to Los Rodeos, including the two aircraft involved in the accident. The airport quickly became congested with parked airplanes blocking the only taxiway and forcing departing aircraft to taxi on the runway instead. Patches of thick fog were drifting across the airfield, so visibility was greatly reduced for pilots and the control tower, which caused confusion. Immediately after lining up, the KLM captain advanced the throttles and the aircraft started to move forward.[31] Meurs advised him that ATC clearance had not yet been given and van Zanten responded: "No, I know that. Go ahead, ask." Meurs then radioed the tower that they were "ready for takeoff" and "waiting for our ATC clearance". The KLM crew then received instructions that specified the route that the aircraft was to follow after takeoff. The instructions used the word "takeoff," but did not include an explicit statement that they were cleared for takeoff. Meurs read the flight clearance back to the controller, completing the readback with the statement: "We are now at takeoff."[4] Van Zanten interrupted the co-pilot's readback with the comment, "We're going."[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. 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. 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.[32] 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 three-second-long shrill sound (or heterodyne). This caused the KLM crew to miss the crucial latter portion of the tower's response. The Pan Am crew's transmission was "We're still taxiing down the runway, the Clipper 1736!" This message was also blocked by the interference and inaudible to the KLM crew. 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.[33] Due to the fog, neither crew was able to see the other plane on the runway ahead of them. In addition, neither of the aircraft could be seen from the control tower, and the airport was not equipped with ground radar.[4] After the KLM plane had started its takeoff roll, the tower instructed the Pan Am crew to "report when runway clear." The Pan Am crew replied: "OK, will report when we're clear." 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?" Van Zanten emphatically replied "Oh, yes" and continued with the takeoff.[29]
