Viz reported as 3000m. Given the proximity of Fath to Karaj (5nms) and that Fath sits more or less on the final approach to Karah, is this a case of during a non precision approach aiming for the first runway that they saw? The far smaller runway at Fath perhaps giving the illusion that it was farther away than it really was? Very sad, and given that something similar happened almost happened in November, surely avoidable.
