A few folks on duty Sunday morning & other sundry witnesses swear they saw a Japanese reconnaissance plane snooping Oahu a few minutes after dawn 7 Dec. Off shore the destroyer Ward sends a report of spotting and attacking a submarine. A radar station sends a report of a mass of aircraft to the north. Shortly after 08:00 a navy Lt Commander returns from breakfast to his duty as officer of the day at Pacific Fleet HQ. He sees all these messages which have collected while he was away. Another report of a snooper sight comes in & the OD sounds a alarm. Then a explosion holes the Oklahoma causing serious flooding on its port side. Tens of thousands soldiers and Navy men mill about in disgruntled confusion for the remainder of the day.
Meanwhile 280 nm to the North Nagumo listens to his staff argue over who is to blame for sending two full strikes off on a fruitless search at sea based on a garbled report of sighting the US fleet at sea west of Oahu.
