80-G-465397:  MacMillan Arctic Expedition, 1925. The ship’s boom was used to unload the planes at Etah.  This did not give a very good purchase and made the task of taking the planes off the ship a very difficult one.  NA-3 is being unloaded, September 1925.   This expedition was noted for the first productive use of aircraft in an Arctic exploration by Americans.  The three aircraft were NA-1, NA-2, and NA-3.  (2015/10/27).
