Tenerife Disaster
The March 27, 1977 runway collision at Los Rodeos Airport that killed 583 people — the canonical case study through which Weick diagnosed organizational sensemaking failure.
On March 27, 1977, two Boeing 747 aircraft collided on the runway at Los Rodeos Airport on the island of Tenerife, killing 583 people. It remains the deadliest accident in aviation history. The KLM captain, one of the most experienced pilots in the airline's fleet, began his takeoff roll without clearance. He did not lack information. The co-pilot had expressed hesitation. The tower's communications contained cues that the runway was not clear. Fog prevented visual confirmation. Every piece of evidence necessary to avert the disaster was available inside the cockpit. None of it penetrated the interpretation the captain had already committed to: the runway is clear, we are cleared for takeoff, the sequence is proceeding as expected. Weick's 1990 analysis, "The Vulnerable System," transformed Tenerife from an aviation accident into the canonical case study of organizational sensemaking failure — not a story about a bad decision, but a story about an interpretation that committed too early to coherence and then filtered every contradictory cue through its own assumptions.
