Another connection to the hidden UFO history was Harvard's top astronomer, Dr. Donald Menzel, a leading UFO debunker in the 1950s.
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.
Adding to the mystery, Menzel was named in the MJ-12 documents as part of Truman's top secret UFO research panel in the late 1940s.
It included top scientists, military leaders, and government officials, figures like Vannevar Bush, Gordon Gray, Donald Menzel, and even Eisenhower.
