Iran says misaligned radar led to Ukrainian jet downing
Iran said that the misalignment of an air defence unit's radar system was the key "human error" that led to the accidental downing of a Ukrainian passenger plane in January. "A failure occurred due to a human error in following the procedure" for aligning the radar, causing a "107-degree error" in the system, the Iranian Civil Aviation Organisation (CAO) said in a report late Saturday. This error "initiated a hazard chain" that saw further errors committed in the minutes before the plane was shot down, said the CAO document, presented as a "factual report" and not as the final report on the accident investigation. Flight 752, a Ukraine International Airlines jetliner, was struck by two missiles and crashed shortly after taking off from Tehran's main airport on January 8, killing all 176 people on board.
