8. Majestic Twelve UFO Cover-Up

In an investigation of some of the most puzzling UFO sightings in Soviet history, we uncover the work of an underground network of believers and reveal a clandestine 13-year government investigation of UFOs. Many Russian UFO enthusiasts believe that proof of alien encounters exists--but it's being hidden from them! We also meet George Knapp, an American broadcast journalist who traveled to Russia in the early 1990s and believes there's a treasure trove of KGB UFO files that remain top-secret.
