There is little effort made to examine other possible causes of the phenomenas noted. A cup full of sand is carefully removed from the seafloor, beneath the sealed control room of the midget sub, and given to Admiral Ueda to take home.

The next three mini-submarines were either found with their torpedoes still on-board or fired them long after the attack began, so they cannot have been the alleged intruder. Within 75 yards the submarine turned sharply toward our bow and released a torpedo. American historians generally conclude that it was Itou , Japanese historians and veterans believe it was Itou.
That evening they boarded the midget submarines through the lower hatches and went through the intricate procedures for underwater launch. A wrecked mini-sub minus its torpedoes was found in the dump. The warheads on the mini-submarine's torpedoes were moderate in terms of explosive power. If significant portions of the mini-submarine broached between the concussion waves, why then was there no sighting by the many eyes anxiously brought to that area of the harbor in anticipation of the next torpedo to strike? The Pisces V moves in for a closer look. My gyrocompass was out of commission.
