Recent claims by astrophysicist Dr. Beatrice Villoriau suggest Menzel ordered the destruction of Harvard's astronomical photographic plates taken during the 1952 Washington DC UFO flap.
I find it really interesting that you have some of the most prominent debunkers, guys like Menzel, guys like Condon, HP Robertson, who were kinda big shots, who also worked on the Manhattan Project. Condon was involved.
