Continuity mistake: When Thunderfish engages the Japanese I-boat, the first range and bearing indicates that the sub is some 6000 yards distant. Less than a minute later, the range has dropped to 900 yards. That would mean that even if both vessels were on directly opposite courses, their combined closing speed would have to be in excess of 250 nautical miles per hour, impossibly.
