Malmstrom / Echo Flight shutdown
Minuteman missiles at Malmstrom AFB's Echo Flight went offline in March 1967; former officers later linked this to a UFO over the site.
1967 CE · 47.48, -109.35 · status: disputed
The account
In 1996 retired personnel, notably Robert Salas, said a glowing object hovered over a launch facility as missiles became unlaunchable. The claim became a pillar of the 'UFOs and nukes' argument.
The sceptical view
A contemporary Air Force investigation found an electronic fault and no link to any UFO; skeptic Robert Sheaffer argues the Oscar Flight UFO was probably Mars and that no missiles failed there. In 2025 the Pentagon was reported to have attributed the outage to a classified electromagnetic-pulse test; Salas disputes this.
The researched reading
The missile outage is real and documented; the UFO above the silos comes from testimony decades later. An internal test or fault is more plausible than an outside intelligence.
| Explanation | Weight | Why |
|---|---|---|
| Secret human technology | 32% | The 1967 unit history noted the Echo Flight fault looked "EMP or electrostatic" in nature, and 2025 reporting said AARO attributed it to an unannounced electromagnetic-pulse test; critics dispute the timing and the lack of damage. |
| Perception, memory or mind | 24% | The UFO link appeared nearly 30 years later; Robert Salas first placed it at Echo Flight, then at Oscar Flight, and recollections were shaped by retelling. |
| Something known, misidentified | 18% | Robert Sheaffer argues the glowing object at Oscar Flight was probably Mars, bright in March 1967; guards seeing lights over the site are common. |
| Genuinely anomalous | 12% | A real shutdown of ten missiles with no confirmed cause keeps some room open, but the UFO connection lacks contemporaneous evidence. |
| A known natural phenomenon | 8% | Investigators considered power transients and a storm; such faults can trip the safety logic of the missiles. |
| A hoax or fabrication | 4% | The officers appear sincere; deliberate invention is unlikely. |
| A poorly understood natural phenomenon | 2% | No unusual atmospheric phenomenon was reported. |
Official position: The Air Force’s 1967 investigation found an electronic fault and no UFO connection; 2025 reporting attributed it to a classified EMP test.
