This week on World of Aviation, Al Malmberg commemorates the 84th anniversary of the attack on Pearl Harbor, which occurred on December 7, 1941. To help mark the occasion, he welcomes back Karl Zingheim, the official historian of the USS Midway. Together they explore why the United States was caught so flat-footed that morning, despite clear signs that Japan was preparing for an attack. They examine the decisions that led to the battleships being grouped together in the harbor and discuss whether there were answers—or missed opportunities—that might have changed history. Join us for a compelling and thoughtful look back at one of aviation’s most pivotal moments.
