On the morning of 7 December 1941, did the USS Arizona (BB-39) succumb to a torpedo attack, or did she fall victim to precision horizontal bombing? From the same team who concluded in the December 1999 issue of Naval History that a second Imperial Japanese Navy submarine had entered Pearl Harbor comes this analysis of motion-picture photography showing the destruction of the Arizona . The image above is purported to be a frame from the original color film. A special featuring this analysis premieres 2 December on The Discovery Channel.
