Major iceberg forming in Antarctica: scientists

NASA's DC-8 flies across a crack, 18 miles (29 km) in length, forming across the Pine Island Glacier ice shelf in this October 26, 2011 handout photograph. Scientists expect the crack to propagate and the ice shelf to calve an iceberg of more than 300 square miles (483 square km) in the coming months. [Photo/Agencies]
