On this bonus true crime companion episode, Bryce travels to Denver, Colorado, where the crash of another airplane, along the same route as flight 409, raises suspicions about what really happened. The case would go on to live in infamy as the second of its kind to ever occur in the United States, and the first in which cameras would be allowed into a court of law. Audiences should listen to Episode 9: Mystery on Medicine Bow before diving in.
