On 21 January 1980 Iran Air Flight 291, a Boeing 727 (EP-IRD) on a scheduled flight from Mashhad, struck a mountain in the Alborz range while descending toward Tehran-Mehrabad in night, snow and fog. The aircraft disintegrated on impact and all 128 occupants were killed. Air traffic controllers had returned to work that day after a strike.
