DHAKA, Bangladesh — Day after day, the grim drudgery of digging for bodies had progressed at Rana Plaza. Talk of rescuing survivors had faded. This was the recovery phase, and what was being recovered were corpses, the numbers spinning remorselessly forward: 700 dead became 800, then 900, with no end in sight.

By Friday morning, the number had pushed above 1,000. And then, late in the afternoon, a soldier from the Bangladeshi Army, standing atop the rubble of the wrecked building, noticed an iron rod that seemed to be moving. There was a noise, a voice. Rescuers hurriedly carved a hole through a concrete pillar. Television stations in Bangladesh cut to the scene: a woman, gasping, was alive in the wreckage, nearly 17 full days after Rana Plaza had collapsed.

A new number was announced: One. A female garment worker named Reshma. A survivor. A miracle.

“Save me!” rescuers heard her shout, before they pulled her into the afternoon light, her face powdered in dust as she was placed on a stretcher.

The Rana Plaza collapse is now considered the deadliest disaster in the history of the garment industry. Five factories were operating inside the building when the structure pancaked downward. The carnage was horrific and has focused global attention on unsafe conditions in Bangladeshi garment factories that make clothing for North American and European consumers — especially since there were advance warnings that the structure was unsafe.
