After encountering the Japanese "0" reconnaissance plane and finding that Pearl Harbor was full of pre-World War II warships, the officers and men on board realized that their aircraft carrier had gone through the time tunnel and returned to Pearl Harbor on the eve of World War II. The officers and men on board further discovered that the Japanese aircraft carrier fleet, which was about to attack Pearl Harbor and inspired the war, either launched a preemptive attack on the Japanese fleet with its own advanced fighters and missiles.
