In March, Indonesian officials and local fishermen rescued 75 people from atop the overturned hull of a boat off the coast of Indonesia’s northern province of Aceh. Another 67 passengers, including at least 28 children, had been killed when the boat capsized, according to the United Nations High Commissioner for Refugees. Until now, little was known about how the boat capsized, or why. (AP Video/Edna Tarigan)
