No Warning

S15, E8: On approach to a remote town in Indonesia’s Papua province, Trigana Air Service Flight 267 vanishes. A treacherous search on Tanggo Mountain leads to the worst possible news: the plane is demolished and there are no survivors. Local investigators face intense pressure to determine why the turboprop crashed, but without recorded flight data, the plane’s cockpit voice recorder becomes their last hope. What they discover is a series of deadly factors—chief among them two overconfident pilots who thought they knew the route better than they had.
