During the peak production periods of WWII, the Doulglas Aircraft Company rolled a completed, ready-for-service DC-3 off the end of their assembly line every 33 minutes. Rosie the Riveter and her fellow workers at Douglas did this 24 hours a day, seven days a week, 52 weeks out of the year, producing 10,147 airplanes by war's end. For this reason alone we can appreciate why when asked by one of his fellow flag rank officers after the Japanese attack on Pearl Harbor why he seemed a bit pensive rather than elated, Admiral Yamamoto is reported to have sighed: "I feel we have only wakened a sleeping giant and filled him with a terrible resolve."
