Tenerife airport disaster
For just those reasons, it was hard not to imagine what a story it would be - and how much carnage might result - should two of these behemoths ever hit each other. A few moments later, the lights of the KLM emerge out of the grayness, dead ahead, 2, feet away and closing fast.
The KLM aircraft's undercarriage and engines hit the top of the Pan Am plane at speed, resulting in a catastrophic crash. 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.

The controller then immediately added "stand by for takeoff, I will call you",  indicating that he had not intended the clearance to be interpreted as a takeoff clearance. The first officer had intervened when Veldhuyzen van Zanten first opened the throttles, but had then failed to do so on the second occasion. The instructions used the word "takeoff," but did not include an explicit statement that they were cleared for takeoff. 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. Immediately after lining up, the KLM captain advanced the throttles and the aircraft started to move forward. 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. It differs from using a telephone, for example, as only one party can speak at a time, and has no idea what his message actually sounds like over the air. The KLM crew then received instructions that specified the route that the aircraft was to follow after takeoff. At the same time, having wheeled into position at the end, Van Zanten comes to a stop. If two or more microphones are clicked at the same instant, the transmissions cancel each other out, delivering a noisy occlusion of static or a high-pitched squeal called a heterodyne. The accident, the worst of its kind in history, now forms an essential part of a pilot's training. Despite bleeding from his head, Warren jumped from the plane, severing two tendons in his foot, while Caroline also jumped and broke the bones in her shoulder. The KLM , also blue and white, is named the Rhine. Another complication was congestion at the airport, which had cut off the usual access to runway 30, which the planes were using to depart. But what exactly is turbulence and how does it happen?
Just thinking about it gives me the chills. The controller then immediately added "stand by for takeoff, I will call you",  indicating that he had not intended the clearance to be interpreted as a takeoff clearance.
Source:YouTube It was an unfortunate series of very unfortunate events that led to the deadliest aviation disaster of all time. 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.
The control tower and the crews of both planes were unable to see one another. The collision of the two planes was attributed to a number of issues.
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. 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,  ripping apart the center of the Pan Am jet almost directly above the wing.

It differs from using a telephone, for example, as only one party can speak at a time, and has no idea what his message actually sounds like over the air. The word "takeoff" is now spoken only when the actual takeoff clearance is given, or when cancelling that same clearance i. Had the plane turned at the third exit as instructed, the collision would not have occurred. 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 moment of impact. Picture: Wikimedia CommonsSource:Supplied The refuelling of KLM, which made the plane heavier and less capable of clearing Pan Am as they were heading for collision — and the fact it fuelled the fire — has also been noted. He lives in Virginia with his wife, Dorothy. Get off! The Pan Am crew's transmission was "We're still taxiing down the runway, the Clipper ! Up until that point, aircrew and controllers should use the word "departure" in its place e. Meanwhile, the pilots in KLM got a route clearance from air traffic control. Pilots and controllers communicate via two-way VHF radios. Probable cause[ edit ] The investigation concluded that the fundamental cause of the accident was that captain Veldhuyzen van Zanten attempted to take off without clearance. As Smith explained, communication was via two-way VHF radios, and on these radios, if two transmissions were sent simultaneously, they cancelled each other out — leading to words being missed and messages misunderstood.
