On a frigid February morning in 1985, a Boeing 727 belonging to Iberia Airlines was destined for a routine flight. Carrying 148 passengers and crew, Flight 610 departed from Madrid for the short journey to Bilbao. However, unbeknownst to those on board, the flight was about to descend into tragedy due to a series of critical misjudgments by the flight crew.
The Crew and Context
At the helm of the aircraft was Captain Jose Luis Patino, a seasoned pilot with 19 years of experience and over 13,000 flying hours. Notably, Patino had recently been reinstated after a strike that had led to the dismissal of several Iberia pilots, raising concerns about his emotional state.
First Officer Emilio Lopez Pena, who had over 5000 flying hours, was tasked with flying the plane, while Flight Engineer Gregorio Arrobo Martin, the least experienced of the crew, assisted in the cockpit. As the aircraft pushed back from the gate around 8:40 AM, alarms would soon ring, not only in the cockpit but across the airline landscape.
The Flight Takes Off
Flight 610 lifted off effortlessly and reached its cruising altitude of 26,000 feet. Initial reports indicated that the flight was proceeding normally, with the pilots discussing routine matters. However, a stark shift in Captain Patino's demeanor occurred after a brief conversation; he became noticeably silent.
Despite this unusual behavior, the plan seemed in good shape as the flight neared its approach to the fog-laden Bilbao Airport surrounded by mountains. As the pilots prepared for their descent, they received weather updates and began their approach procedures, not realizing that crucial information was missing from their approach charts.
Errors in Approach
At approximately 9:07 AM, the first officer reported to air traffic control that they were descending through 13,000 feet towards 10,000. However, an air traffic controller offered them a shortcut to the runway based on light traffic, which the first officer initially considered before looking to Patino for guidance. Patino's silent gesture revealed his intentions to follow the standard procedure instead.
This decision was, in part, driven by recent tensions surrounding Patino’s reinstatement and salary issues with the airline, leading to a somewhat passive approach that would ultimately ruin their flight.
Descent into Confusion
As they began their descent, an unexpected series of mistakes unfolded. The first officer selected a descent rate of 1500 feet per minute—noticing a higher altitude descent rate than required for the standard procedure as they approached the approach fix. The captain failed to select the altitude properly on the autopilot, which meant the plane continued to descend unchecked—drawing closer to the mountains lurking below.
An altitude alert system announced to the pilots that they were descending below their selected altitude, but both pilots misinterpreted the alarms due to their operational mindsets, leading them to dismiss these critical warnings.
The Final Moments
At 9:27 AM, as the aircraft skimmed below the minimum safe altitude veiled in fog, disaster struck. A television mast—a structure not indicated on their charts—appeared directly in their path. In mere seconds, the left wing collided with the mast, ripping off the aircraft and sending the plane into an uncontrollable spiral.
Within moments, the Boeing 727 crashed into the valley of Mount OES, tragically taking the lives of all 148 passengers and crew members aboard.
Following the disaster, investigations revealed a multitude of safety oversights, including the need for enhanced cockpit communication protocols and recommendations to modernize outdated altimeter systems. Crucially omitted from the report was the absence of a ground proximity warning system, a technology that could have provided critical alerts to the crew.
While such equipment had been mandated for aircraft in the United States for a decade, Spain lagged behind in making it compulsory. The introduction of this vital technology in subsequent years markedly reduced the frequency of similar tragedies worldwide.
The heartbreaking story of Iberia Flight 610 serves as a harrowing reminder of the vital importance of clear communication, situational awareness, and adherence to safety protocols in aviation. The consequences of misjudgment and outdated technology echoed beyond this tragedy, marking a pivotal moment in aviation safety reforms that would ultimately save lives in the years to come.
