From newspapers of Sept. 17, 1945: The U.S. Navy plans to tow the Japanese battleship Nagato hundreds of miles out into the Pacific and drop an atomic bomb on it to gauge the effects. The Navy wants to see if the 32,700-ton ship will be destroyed and what effect the bomb will have on the water. An American B-29 was shot down by Soviet fighter planes over Korea on Aug. 29, it is disclosed in Tokyo. The B-29 was carrying supplies to an Allied prison camp inside the Soviet-occupied portion of Korea. None of the 13 crewmen was injured; Moscow has apologized for the incident. Japanese military commanders formally surrender their forces in Hong Kong. The surrender had been delayed many times since British forces entered Hong Kong on Aug. 30. The trial of the "Beast of Belsen" will begin in Lueneburg, Germany, today. Josef Kramer, director of the Belsen concentration camp, and 44 of his SS aides face death or imprisonment if convicted by the military tribunal. Among the evidence to be presented are films of the degradation suffered by inmates of Belsen and Auschwitz, where Kramer also served. The accused, 21 of whom are women, will be defended by British officers who are lawyers.
