Joint POW/MIA Personnel Accounting Command forensic anthropologists Mindy Simonson, left, and Laurel Freas compare notes regarding the placement of marking flags on the excavation site where a series of bore holes will be melted on a glacier near Koge Bay, Greenland, Aug. 13, 2013. Once the flags are set with two meter spacing, the team can begin melting bore holes to lower a subsurface camera to look for a U.S. Coast Guard World War II-era J2F-4 Grumman Duck aircraft that reportedly crashed at that site on Nov. 29, 1942.
