Sgt Maj Robert O Dean, "I Held One Of The Highest Clearances In the U S Army" "Cosmic Top Secret"

Robert Orel Dean (March 2, 1929 – October 11, 2018) was an American ufologist from Tucson, Arizona.

Dean retired from the U.S. Army as a Command Sergeant Major after a 28-year career. He appeared on radio programs, TV documentaries and at conferences discussing the subject of UFOs and a government cover up of alien visitations to Earth.[1] Dean claimed to have viewed a classified government document called "The Assessment" that allegedly discussed threats posed by alien activity on Earth, and concluded that no such threats existed.[2] Dean said he considers himself a professional UFO researcher and had "Cosmic Top Secret" clearance while in the military.
