Rough terrain and rainfall were hampering the search Wednesday for clues into why a China Eastern plane inexplicably fell from the sky and crashed into a wooded mountainside earlier this week, presumably killing all 132 people on board.
Under rainy conditions, searchers using hand tools, drones and sniffer dogs were combing the crash site and a debris field spread across steep, heavily forested slopes in southern China for the black boxes containing the flight data and cockpit voice recorders, a well as any human remains.
