Ex US Army U-1A 55-3288. To N1457H in 1973 and used as an instructional airframe at Merril Field, Anchorage. Later civilianized by Western World Retrievals who used it on a 1985-86 expedition to Greenland (note the "Western World Retrievals Inc - Greenland Expedition 85-86" logo), in an attempt to find and retrieve six P-38 Lightnings which, having made a forced landing there in 1942, became buried under the icecap. In 1988 the aircraft was damaged near Wrangell AK, while registered to Diamond Aviation, when it hit a snow-bank in poor visibility. While attempting to salvage the damaged Otter, a Bell 205 dropped it from 1,500ft resulting in a total write off!
