Interesting info. I still believe that FDR and some of the brass had many warnings of the impending attack. The American people did not want us involved in the European war and Roosevelt did while feigning the opposite. He cut off oil and metal supplies to Japan to start the inevitable ball rolling. By allowing the Japanese attack, our entering both the European and Pacific theaters was ensured and a nation was galvanized. FDR was a socialist snake in oh so many ways.
None of the Marines onboard were surprised about the attack as the Japs had been over-flying the the Phillipines for several days.
