Keyhoe, Scully, and UFOs on CBS in 1958
Those who saw that show, then, or in a more recent UFO documentary, would see a conspiracy of silence in the sound black out.
I looked, on YouTube, for a clip of the show but could find none.
However, I did find a Mike Wallace interview with Donald Keyhoe, which is interesting I think:
And one with Major Keyhoe and Frank Scully, the author of Behind the Flying Saucers about the alleged 1948 Aztec crash:
Both "interview" segments provide the UFO mind-set in the late 1950s, but little more actually.
If anyone can find the "sound black out show," let me know. I'd like to put it online for the edification of conspiracy theorists or those who need to see why some UFO buffs are conspiracy theorists.
