Tiny Details Led to Horrific Crash of Dan-Air 1008

On the 25th of April 1980, a Boeing 727 carrying British tourists to Tenerife in the Canary Islands flew off course in fog and slammed into the side of La Esperanza, killing all 146 passengers and crew. The setting for the disaster was familiar for all the wrong reasons: just three years earlier, the very same airport on this tiny Atlantic island had played host to the deadliest aircraft accident in history. The curse of Tenerife, which had already claimed so many lives, had struck again. But in trying to piece together why the crew of Dan-Air flight 1008 found themselves on a collision course with a mountain, facing dire warnings but unsure which way to turn, Spanish and British investigators came to a deadlock. Was the air traffic controller’s imprecise language the cause, or did ultimate responsibility for avoiding terrain still lie with the pilots? The arguments hinged on a single letter in a single word — one word that changed absolutely everything about the situation. But this confusion, much like Tenerife’s infamous fog, obscured the real problem: a system which was so deficient that the absence of a single letter could lead to disaster.
