The DC-3 on Floats in Greenville, Maine has been the subject of widespread interest and mystique within the flying community for decades. Many a pilot or aviation enthusiast was able to witness the world's largest floatplane in action, knew someone who saw it, or saw a picture over the years. However, few have known the story behind the unusual seaplane, how it came to be, or what became of it. Now for the first time, readers can learn the fascinating and untold history of C-47/DC-3 Aircraft on Amphibious Floats. From the little known project undertaken by the Army Air Corps and EDO Floats during the Second World War to convert Douglas C-47s into amphibious seaplanes, to the similarly ambitious effort by HBF Inc. and Folsom's Flying Service decades later that led to the first and only civilian conversion of this type.
