The 1967 Malmstrom Incident: UFO Sightings and Unexplained Minuteman Missile Shutdowns
In March 1967 at Malmstrom AFB, security personnel and launch crews reported unidentified flying objects near Minuteman missiles, including one hovering above a launch facility, after which the Echo-Flight missiles shifted from alert to No-Go and could not be brought back online, while DMCCC Robert Salas recalls a red-glow UFO outside the front gate and a guard being injured before evacuation, communications with patrols were lost and further UFOs were sighted near other launch facilities as the missiles remained shut down; a Boeing-led investigation found no conventional cause and showed similar effects could be produced only by injecting a 10-volt pulse onto a data line, implying an electromagnetic pulse from an unknown source; the episode was treated as a national-security incident with simultaneous outages across flights, though the Air Force publicly maintained UFOs did not affect national security, while declassified documents from the 341st Strategic Missile Wing and SAC communications corroborate the sightings and shutdowns and call for further examination and declassification, leaving the overall picture unsettled.
