Pearl Harbour: Mystery of the Killer Subs (2010x7)

Air date: Apr 10, 2010

For decades it has been thought that a bomb dropped by a Japanese aircraft sank the USS Arizona during World War II. However, the recent discovery of a group of small Japanese submarines in and around Pearl Harbour has raised questions about the battleship's final hours. This film follows a team of expert investigators, who journey to the seafloor to explore the wreckage of a newly discovered sub, and questions whether this mini-sub, and its two-person crew, made it into Pearl Harbour to fire torpedoes at the Arizona. With unprecedented access to the remains of the Arizona and other unique evidence, including aerial photos taken by Japanese aircraft and testimonials from US and Japanese veterans, Pearl Harbour: Mystery of the Killer Subs investigates the possibility that these tiny but lethal mini-subs may have played a crucial and previously unsuspected part in the tragic events of that 'Day of Infamy'.
