The 20 year anniversary of one of the strangest tales in modern American religious history is quickly approaching. On March 26th, March 26, 1997 Marshall Herff Applewhite led a group of 39 devoted followers to their final destination. In their minds they were headed to a spaceship following the Hale-Bopp Comet where they would be taken and transformed into perfect angelic alien beings, a state in which they would live forever. We're joined by Benjamin E. Zeller, Religious Historian and Author of the book "Heaven's Gate: America's UFO Religion."
