1967 Malmstrom AFB Incident: A Retired Officer's Claim That UFOs Disabled 10 Minuteman ICBMs
To the point
Former US Air Force launch officer Robert Salas claims that in 1967 UFOs disrupted launch controls at Malmstrom Air Force Base, causing 10 Minuteman missiles with warheads to fail after strange overhead lights were seen and an apparent intrusion was reported, and although a Boeing investigation could not explain how the warning signal was injected or the missiles disabled, Salas has since spoken publicly proposing that intelligent non‑human civilizations may have visited Earth to prevent nuclear war.
