NASA's DC-8 flew over the Pine Island Glacier Ice Shelf on Oct. 14, 2011, as part of Operation IceBridge. A large, long-running crack was plainly visible across the ice shelf. The DC-8 took off on Oct. 26, 2011, to collect more data on the ice shelf and the crack. The area beyond the crack that could calve in the coming months covers about 310 square miles (800 sq. km).

The 3D flythough of the rift in the Pine Island Glacier on Oct. 26, 2011, created entirely through photogrammetric processing.of Digital Mapping System imagery taken from NASA's DC-8 aircraft during an Operation IceBridge field campaign.
