Finding The Fault
So Iwasaki started to work, and it wasn’t long before he discovered the critical single-digit inaccuracy. Apparently, a transcription error had occurred in a report that had been radioed into Sasebo from Naha on February 27, 1944 — just a couple of days after the Grayback had returned to base for the final time during World War II. A Nakajima B5N bomber that had taken off from an aircraft carrier launched an attack on the target, according to the relevant Japanese statement.
100-Mile Error
In an interview with The New York Times published in November of this year, Iwasaki stated that in that radio recording, there was a longitude and a latitude of the assault, both of which are rather well documented. According to the Navy, these coordinates pointed to a position that was more than 100 miles away from the one that the United States Navy had believed to be the accurate location since 1949, which was unexpected.
