Wreckage found in Greenland of 1942 Coast Guard rescue plane WASHINGTON, Jan. 14 (UPI) -- A Coast Guard rescue aircraft missing for 70 years with three men aboard has been found beneath the ice in Greenland, Coast Guard officials announced Monday. The wreck of the J2F-4 Grumman Duck, which crashed Nov. 29, 1942, was found 38 feet below the surface of the ice near Koge Bay, the Coast Guard said in a statement. Coast Guard Lt. John Pritchard and Petty Officer 1st Class Benjamin Bottoms had landed on the Greenland Ice Cap to retrieve U.S. Army Air Force Cpl. Loren Howarth, one of seven crew members of a B-17 crew that had crashed. While flying back to the Coast Guard Cutter Northland, the plane encountered whiteout conditions and crashed. A U.S. Army aircrew spotted the wrecked Duck a week later and reported no signs of life. The crewmen who remained at the site of the crashed B-17 were airdropped supplies until they were rescued about six months later. A team from the U.S. Coast Guard and North South Polar Inc. used historical information, ground penetrating radar, a magnetometer and metal detection equipment to isolate the location of the crash, the statement said. A specially designed camera scope lowered through holes melted in the ice found black cables consistent with wiring using in the amphibious aircraft.
