Elements of this last flight most likely followed the Ryukyu flyway southwest to the many small islands north of Okinawa, where U.S. forces were still on alert at the potential end of hostilities. Endo served as radioman during the mission, sending Ugaki's final messages, the last of which at 19:24 reported that the plane had begun its dive onto an American vessel. However, U.S. Navy records do not indicate any successful "kamikaze" attack on that day, and it is likely that all aircraft on the mission (with the exception of three that returned due to engine problems) crashed into the ocean, struck down by American anti-aircraft fire. Although there are no precise accounts of an intercept made by Navy or Marine fighters or Pacific Fleet surface units against enemy aircraft in this vicinity at the time of surrender, it is possible further research may reveal more detail as to which ships (if any) were attacked.
