"Oh the humanity!" were the famous words spoken by news reporter Herb Morrison when on May 6, 1937, the Nazi-funded airship Hindenburg burst into flames and crashed into a New Jersey airfield. My guest is best-selling author Michael McCarthy, and his new book is called "The Hidden Hindenburg: The Untold Story of the Tragedy, the Nazi Secrets, and the Quest to Rule the Skies." He tells the fascinating story of the development of Germany's zeppelin program, headed by the colorful Hugo Eckener, shares details of the terrible disaster, and reveals the truth about what really caused the Hindenburg to catch on fire. Become a Most Notorious patron at: www.patreon.com/mostnotoriousLearn more about your ad choices.
