WOW: Sub That 80 Americans Died on Found After 75 Years. “Tim Taylor, who runs a project dedicated to finding the 52 US submarines lost in action during World War II, says his team has found the USS Grayback off Okinawa, the New York Times reports. The sub, which sank more than a dozen Japanese ships and rescued a group of downed American airmen, left Pearl Harbor on Jan. 28, 1944, for its 10th combat mission and never returned. Japanese records translated after the war said a plane had hit the sub with a 500-pound bomb and gave the latitude and longitude. But last year, Yutaka Iwasaki, a Japanese researcher who works with Taylor’s team, discovered that one digit had been mistranslated.”
