Quote from the article:
“In 1966 the Minuteman II ICBM was deployed to 5 SAC bases, Malmstrom Air Force Base, Ellsworth Air Force Base, Minot Air Force Base, F.E. Warren Air Force Base, and Whiteman Air Force Base. Malmstrom Air Force Base was also selected as the location for an additional Minuteman squadron, and LFs and LCFs were consequently constructed at this base. The first Minuteman II was deployed at Grand Forks Air Force Base, North Dakota, in August 1965.
In early 1966 UFOs were being reported at these same SAC bases.”
