 Absorbed in trying to get a clearer picture on S-14's location, Seacrest failed to report the bearing and range of S-13 ("Ehime Maru") to Waddle during Waddle's periscope search, which Seacrest's monitors now showed was about away and closing.During Waddle's periscope search, Seacrest was busy operating other control room instruments and did not actively monitor his fire control displays.After the periscope search was over, and hearing Waddle's report of no visual contacts, Seacrest decided that his information for S-13 was incorrect and manually respotted the S-13 contact on his screen to a distance of away.
