On March 27, 1977, two Boeing 747 passenger jets collided on the runway at Tenerife airport in the Canary Islands, resulting in the deadliest aviation accident in history. The collision killed 583 people and left only 61 survivors, most of whom sustained serious injuries.
The two aircraft involved in the collision were a KLM Boeing 747 and a Pan Am Boeing 747. The KLM flight was scheduled to depart for Amsterdam, while the Pan Am flight was waiting to take off for Los Angeles. However, due to a bomb threat at the nearby Gran Canaria airport, both flights were diverted to Tenerife, causing the airport to become overcrowded with parked planes and stranded passengers.
As the two aircraft taxied on the runway, the KLM captain attempted to take off without clearance from air traffic control, mistaking the controller's response as permission to depart. The Pan Am crew, meanwhile, was instructed to exit the runway at the third taxiway, but missed it due to poor visibility caused by heavy fog. This resulted in the KLM aircraft colliding with the Pan Am aircraft as it was still on the runway.
The collision caused a massive explosion and fire, killing everyone on board the Pan Am flight and most of those on board the KLM flight. The crash investigation revealed that the KLM captain's decision to take off without clearance was the primary cause of the accident, although other contributing factors were also identified, including miscommunication between the air traffic controllers and the pilots, as well as the crowded and chaotic airport conditions.
The Tenerife airport disaster was a tragic event that had a profound impact on the aviation industry. As a result of the crash, new safety regulations were implemented, such as the standardization of international aviation phraseology and the requirement for crew resource management training for all pilots. These changes have helped to prevent similar accidents from occurring in the future.
Today, we remember the victims of the Tenerife airport disaster and honor the brave first responders who risked their lives to save those who survived. We also recognize the ongoing efforts of the aviation industry to improve safety and prevent accidents, so that tragedies like this one may never happen again.
