80-G-465379:  MacMillan Arctic Expedition, 1925.  Lieutenant Commander E. F. MacDonald trying out an Eskimo kayak.  These are very “tippy”.  The sudden twisting of one’s head being sufficient at times to precipitate the experienced paddler into the water. 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).
