The Tenerife disaster, which occurred on 27 March 1977, remains the accident with the highest number of airliner passenger fatalities, as well as the most recent fatal and notable incident involving a KLM aircraft. 583 people died when a KLM [[Boeing 747-200B]] attempted to take off without clearance and collided with a taxiing [[Pan American World Airways|Pan Am]] [[Boeing 747-100]] at [[Los Rodeos Airport]] on the [[Canary Island]] of [[Tenerife]], [[Spain]]. No one on the KLM 747 survived (14 crew, 234 passengers were killed) while 61 of the 396 passengers and crew on the Pan Am aircraft survived. Pilot error from the KLM aircraft was the primary cause. Owing to a communication misunderstanding, the KLM captain thought he had clearance for takeoff.<ref name="Tonyleather">{{cite web |last=Hamilton |first=Sophia |date=2023-09-29 |title=Top 10 Reasons for Plane Crashes |url=https://airlinespolicy.com/blog/top-10-reasons-for-plane-crashes/ |access-date=2023-11-25 |archive-date=25 November 2023 |archive-url=https://web.archive.org/web/20231125120308/https://airlinespolicy.com/blog/top-10-reasons-for-plane-crashes/ |url-status=live }}</ref><ref>{{cite web|last=Sebastien Freissinet|title=The Tenerife crash-March 27th, 1977|url=http://www.1001crash.com/index-page-tenerife-lg-2.html|access-date=7 May 2012|archive-date=11 April 2022|archive-url=https://web.archive.org/web/20220411111436/https://www.1001crash.com/index-page-tenerife-lg-2.html|url-status=live}}</ref> Another cause was dense fog, meaning the KLM flight crew was unable to see the Pan Am aircraft on the runway until immediately before the collision.<ref name=ASN>{{cite web|title=ASN Accident Description|url=https://asn.flightsafety.org/asndb/329179|website=Aviation Safety Network|access-date=26 November 2015|archive-date=2 April 2011|archive-url=https://web.archive.org/web/20110402172426/http://aviation-safety.net/database/record.php?id=19770327-0|url-status=live}}</ref> The accident had a lasting influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in air traffic control (ATC) communication by both controllers and pilots alike, thereby reducing the chance for misunderstandings. As part of these changes, the word "takeoff" was removed from general usage, and is only spoken by ATC when clearing an aircraft to take off.<ref>{{cite web|url=http://www.tenerife-information-centre.com/tenerife-airport-disaster.html|title=The Tenerife Airport Disaster – the worst in aviation history|work=The Tenerife Information Centre|access-date=29 October 2014|archive-date=11 April 2022|archive-url=https://web.archive.org/web/20220411111410/https://www.tenerife-information-centre.com/tenerife-airport-disaster.html|url-status=live}}</ref>
