Published on 26 Mar 2017. 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."
