Malmstrom AFB Nuclear Missile Shutdown

Malmstrom Air Force Base, Montana, USA | March 1967

On the morning of 16 March 1967, all ten Minuteman I ICBMs at Malmstrom Air Force Base's Echo Flight launch facility went offline simultaneously. A guard above ground reported a large round object hovering over the site. Eight days later, the same thing happened at Oscar Flight: a glowing red oval at the front gate, frightened guards, and ten more missiles dropping into "no-go" status one by one. Boeing engineers who flew in from Seattle could not explain the failures. The Air Force classified the incidents and told the crew commanders to keep quiet. The missiles sat offline for most of a day while the United States' nuclear deterrent was, in that small patch of Montana, effectively nullified.

Echo Flight: 16 March 1967

Ten missiles go offline in seconds. Boeing cannot explain it.

At 08:30, at the Echo Flight missile launch facility between Winfred and Hilger, Montana, First Lieutenant Walter Figel, deputy crew commander, watched one Minuteman go "no-go" on his console. He called the topside guard. The guard reported a large, round object hovering over the site. Within seconds, all nine remaining missiles shut down. Ten Minuteman I ICBMs, each carrying a nuclear warhead, simultaneously offline.

Strike teams were dispatched. Boeing engineers flew in from Seattle. They tested the missiles, the guidance systems, the control equipment. They found nothing wrong. The simultaneous failure of multiply-redundant systems across ten separate launch facilities had no technical explanation. The crew commanders, Figel and his commanding officer First Lieutenant Eric Carlson, were debriefed and told to keep quiet.


Oscar Flight: 24 March 1967

Eight days later, the same thing happens. This time there is a red oval at the gate.

Late in the evening of 24 March, at the Oscar Flight Launch Control Centre south of Roy, Montana, an airman saw a star-like object zigzagging above. A larger light appeared. He and his NCO watched the lights manoeuvre before calling their underground commander, First Lieutenant Robert Salas. Salas told them to keep watching. Minutes later, the NCO called back: a glowing red oval object was hovering outside the front gate. The guards were frightened. One was reportedly injured.

Almost immediately, Salas's missiles began dropping into "no-go" status, one by one, until all ten were offline. His commander, Captain Frederick Meiwald, woke from a rest period to find the flight gone. The security guard report was never formally included in the incident documentation.

Are you telling me they don't care about UFOs in general, whether they're from another planet or not? They do care; they care about anything in our airspace.
Robert Salas, MUFON Minnesota Newsletter

The Broader Pattern

Malmstrom was not isolated. UFOs and nuclear weapons share a documented history.

The archive contains direct sighting records for parallel incidents at nuclear facilities. In October 1968, sixteen military personnel at Minot AFB observed UFOs over the Minuteman complex, with radar contact confirmed. In November 1975, Malmstrom experienced a second wave: remote sensors triggered alarms at missile sites, a 300-foot saucer was tracked on radar, targeting systems were reportedly tampered with, and F-106 interceptors were scrambled. NORAD logged the event. Loring AFB and Wurtsmith AFB experienced similar incursions the same month.

In October 2010, at Francis E. Warren AFB in Wyoming, Air Force personnel reported an enormous cigar-shaped craft manoeuvring over the base while 50 Minuteman III missiles went offline for 45 minutes. The direct parallel to Malmstrom 1967, separated by 43 years, is the pattern that Robert Hastings spent four decades documenting.

Project Blue Book

Oscar Flight carries a "BBU" (Blue Book Unknown) designation. The archive holds Blue Book downloads in the NARA collection. Echo Flight was classified separately as an equipment failure. Neither investigation was conducted publicly.


The Evidence

Sworn testimony, NICAP ratings, and a trail that took 30 years to surface.

Robert Salas spent 22 years with the FAA after leaving the Air Force in 1971. He went public in the mid-1990s and co-authored "Faded Giant" with James Klotz in 1998, the first detailed account of Oscar Flight. He has since given sworn testimony at the National Press Club (2010) and submitted written testimony to congressional hearings.

Walter Figel confirmed the core facts of Echo Flight in recorded interviews with Robert Hastings. He initially disputed whether the UFO report was directly connected to the shutdown, but later confirmed that the guard's call came immediately before the missiles failed. Eric Carlson confirmed the basic facts. Frederick Meiwald provided corroborating testimony on Oscar Flight.

Both Echo and Oscar carry a NICAP credibility rating of 5 out of 5 as electromagnetic effect cases. The Eberhart chronology contains seven separate dated entries covering the 1966 to 1967 Malmstrom events. The Hatch *U* Database rates the case 9 out of 10 for credibility.

From the Archive

Nine newsletter articles document Malmstrom across MUFON Minnesota, UFO Newsclipping Service, and Saucer Smear. Key sighting records include S-114024 (Echo Flight), S-114029 (Oscar Flight), S-104369, and S-104383, all with NICAP ratings of 5. Government programme cross-references include Military Investigation and Project Blue Book. See also United States sightings.


Investigation Timeline

From the 16 March shutdown to the 2010 National Press Club testimony.

16 March 1967
Echo Flight ten-missile shutdown
Between 08:30 and 08:45 Mountain Time, all ten Echo Flight Minuteman I ICBMs go from "alert" to "no-go" within seconds. A topside guard reports a large round object hovering over the launch facility. Deputy commander Walter Figel and commander Eric Carlson receive the guard report by phone just before the missile failures.
16 March 1967, afternoon
Strike teams and Boeing engineers respond
Air Force strike teams deploy to the affected launch facilities. Boeing engineers, contracted as the prime Minuteman manufacturer, fly in from Seattle to assess the systems. Their testing of the guidance systems, control equipment, and missile electronics finds nothing wrong.
24 March 1967, late evening
Oscar Flight ten-missile shutdown
A topside airman watches a star-like object zigzagging above. He calls Robert Salas in the Launch Control Centre. Minutes later a larger glowing red oval object hovers outside the front gate. Almost immediately, ten Oscar Flight missiles begin dropping into "no-go" status one by one until the entire flight is offline.
25 March 1967
Crew debriefing and classification
Salas, Meiwald, Figel, and Carlson are debriefed by USAF Office of Special Investigations personnel. The incident is classified. The crew members are told not to discuss the events. The official Air Force record characterises the incidents as "equipment malfunction."
October 1968
Parallel incident at Minot AFB
Sixteen military personnel at Minot AFB, North Dakota, observe unidentified objects over the Minuteman missile complex with radar contact confirmed. The Minot incident establishes that the Malmstrom shutdowns were not isolated occurrences.
November 1975
Second Malmstrom wave
Remote sensors at Malmstrom missile sites trigger alarms over multiple nights. A 300-foot saucer is tracked on radar. Targeting systems are reportedly affected. F-106 interceptors are scrambled. Similar incursions occur at Loring AFB and Wurtsmith AFB the same month.
1971
Salas leaves the Air Force
Robert Salas resigns his commission and joins the Federal Aviation Administration. He spends 22 years with the FAA. The Oscar Flight incident is not publicly discussed during his FAA career.
Mid-1990s
Salas goes public
Robert Salas publishes the first detailed public account of the Oscar Flight incident. The account triggers other former Malmstrom personnel to come forward, including James Klotz, who co-authors "Faded Giant" with Salas.
1998
"Faded Giant" published
Salas and Klotz publish the first book-length account of both Echo and Oscar Flight incidents. The book draws on extensive interviews with former Malmstrom personnel and on the limited declassified Air Force documentation.
October 2010
Francis E. Warren AFB shutdown
Fifty Minuteman III missiles at F. E. Warren AFB in Wyoming go offline for approximately 45 minutes while Air Force personnel report an enormous cigar-shaped craft manoeuvring over the base. The direct parallel to Malmstrom 1967, 43 years later.
27 September 2010
National Press Club testimony
Robert Hastings organises a press conference at the National Press Club in Washington DC at which seven former US Air Force nuclear weapons personnel, including Salas, provide sworn testimony about UFO incidents at nuclear facilities. The conference is the public culmination of Hastings's four-decade documentation effort.
2017 to 2023
Hastings publishes additional testimony
Robert Hastings expands the witness record to over 150 former US nuclear weapons personnel. His ongoing book updates and his website maintain the standing institutional record of UFO incidents at US nuclear facilities from the 1940s onwards.

The Technical Question

Why redundant systems on ten separated missiles failed simultaneously.

The technical detail that gives the Malmstrom incidents their analytical weight is the redundant architecture of the Minuteman I system. Each launch facility was a separate hardened underground silo. Each silo had its own power supply, its own guidance computer, its own communications link to the Launch Control Centre, and its own backup systems for each. The failure of a single missile through electrical or electronic fault was a routine occurrence in the Minuteman force and was handled by the standard maintenance procedures. The simultaneous failure of ten missiles across ten separated launch facilities, all going from alert to no-go within seconds, was not a routine occurrence and had no precedent in the Minuteman operational record.

The Boeing engineering team that flew in from Seattle conducted what is described in the declassified record as a comprehensive systems check. They tested the guidance computers, the launch sequencing electronics, the communications equipment, the power supplies, the backup systems, and the analytical software. They could not identify a single common-mode failure that would have produced the observed pattern. The official explanation that eventually emerged, that "noise" on the data buses produced a logic-glitch shutdown, was contested at the time by the engineering team itself and has been disputed in the subsequent literature.

The institutional response to the Malmstrom incidents was unusual. The Air Force's standard procedure for unexplained equipment failures of this magnitude would have been an extensive investigation, a corrective engineering programme, and broad dissemination of lessons learned. The Echo and Oscar Flight incidents were instead classified, the crew members were instructed not to discuss the events, and no public engineering report was produced. The pattern of institutional suppression, rather than the technical detail of the failure itself, is what gives the Malmstrom case its standing position in the UFO-nuclear literature.

The Hastings Record

Robert Hastings's documentation programme, running from the early 1980s to the present, has produced sworn or recorded testimony from over 150 former US Air Force, Army, and Navy nuclear weapons personnel describing UFO incidents at nuclear facilities. The record spans nuclear weapons storage depots, missile silos, submarine bases, bomber wings, and the Nevada Test Site. Hastings's archive is the single most comprehensive private documentation of military UFO incidents at US nuclear facilities in the public record.
