Malmstrom Air Force Base Missile Shutdown (1967)

The shutdown

On 16 March 1967, the ten Minuteman I intercontinental ballistic missiles on Echo Flight, an underground launch complex between Hilger and Winifred in central Montana, dropped out of alert status. A 341st Strategic Missile Wing history from the period records that the sites "shut-down with No-Go indications" at 0845 that morning. The missiles were restored within about a day. The Air Force's internal account treats the event as an equipment problem, not an anomaly.

The technical explanation that emerged from the records is an electrical one. A transformer short at the Fergus Electric Winifred Substation briefly cut power to Echo Flight and set off the launch facilities' diesel generators. Boeing, which investigated the event, linked the outage to electrical noise on a control line that could have reached all ten missiles through the Sensitive Information Network. The missiles rebooted automatically after roughly 10 to 40 seconds. Boeing's electromagnetic pulse tests were negative, and the Air Force concluded only that Echo Flight had suffered "some type of adverse power effect."

Salas's account

Lt. Robert Salas, then 26, was the missile crew commander underground that night. In his telling, security guards topside reported unexplained lights, then a glowing red object hovering near the front gate, with extreme speeds, abrupt stops and right-angle turns. Minutes later all ten missile warning lights came on at once. Crews ran every check and found no cause. Salas says he was made to sign a nondisclosure statement the following day and kept quiet for roughly 27 years.

He went public in a 1996 Great Falls Tribune interview, which denied any suggestion that he was a "UFO junkie." His fuller account appeared in Faded Giant (2005, co-written with James Klotz), and Robert Hastings's UFOs and Nukes (2008) brought the case to a wider audience. By 2005 Salas was speculating that the government was hiding alien technology, a claim that goes well beyond his 1996 statements.

Investigation and disputes

The central dispute is about a second event. Salas places a parallel incident at Oscar Flight on or around 24 March 1967 and links it to a UFO. The Air Force records he obtained under FOIA describe only Echo Flight, and a Mobile Strike Team that checked nearby flights reported nothing unusual. Fellow officers Eric Carlson and Walter Figel later said Oscar Flight never had such a problem and that there were no UFO reports at Malmstrom. Skeptics note that the Belt, Montana sightings that fit the period were eight days later and about 50 km away, so they cannot explain the shutdown.

Skeptical writers, including Brian Dunning on Skeptoid and Mick West, judge Salas honestly mistaken rather than deceptive. Robert Sheaffer suggested the object was probably the planet Mars. The sources also disagree on timing: Salas remembers a night event, while the Air Force logs give 0845 in the morning.

Current status

In June 2025 the Wall Street Journal reported that the Pentagon had attributed the 1967 event to a classified test of a nuclear electromagnetic pulse device. That is an official explanation for the shutdown, not for any UFO, and it has been reported secondhand; the primary documents should be read before relying on it.

The case is contested. The missile shutdown is documented; the UFO link rests almost entirely on Salas's later testimony and on Oscar Flight, which the surviving records do not support. It is nonetheless one of the few UFO claims tied directly to nuclear weapons, and it remains a staple of the genre.
