A number of reports here. The UN remains open minded as to cause, but I concur that CFIT as a result of black hole approach being the cause. Significant that the airport is not visible from the crash site and the visibility was reported as 5-10 miles in smoke haze. Distance from crash site to runway threshold is 7.8NM. Highly significant too I think that both the co-pilot and flight engineer had flown 17 hours in the previous 24. Tired??
