Part 5/7:
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.
