The US Navy acquired five COA-1 amphibians from the US Army. Receiving the OL-2 designation, they were intended for the 1925 MacMillan Arctic Expedition, with Richard Byrd leading an aviation element of three Loenings: NA-1, NA-2 and NA-3. NA-3 arrived at Squantum on 11 June 1925 and the photo is assumed taken that day. The pilot was Floyd Bennett. Byrd liked Bennett and put him in NA-1. The following year they headed for the North Pole together in a civilian Fokker F.VIIa-3m, Josephine Ford, which Byrd had coded BA-1. Photo by: Leslie Jones / Boston Public Library
