An expedition team of U.S. Coast Guard service members and North South Polar, Inc. scientists and explorers transport an ice melting machine over a crevasse near Koge Bay, Greenland, Aug. 29, 2012. The team used the machine to melt through the ice to locate the possible crash site of a WWII Coast Guard Grumman Duck rescue aircraft missing for 70 years with three men aboard, beneath the surface of a glacier.
