Malmstrom AFB Missile Shutdown 1967

On March 16, 1967, Launch Control Officer Captain Robert Salas was on duty at Echo Flight's underground launch control capsule at Malmstrom AFB when security sentries reported a glowing red-orange orb hovering above the front gate. Minutes later, one after another, all ten Minuteman I ICBMs in Echo Flight went offline — their launch enabling switch status indicators changing from 'ready' to 'no-go.' The sudden simultaneous shutdown of ten independently-powered missiles is considered technically impossible under normal circumstances, as each missile has separate power and guidance systems. Boeing engineers sent to investigate could not replicate or explain the shutdowns. The same phenomenon occurred at Oscar Flight days earlier. Captain Salas has spent decades testifying publicly about the incident, including before Congressional staff in 2021. The event has been verified by multiple declassified documents and former colleague Captain Fred Wahler. The strategic implications — that an unidentified craft could neutralize an entire ICBM flight — represent perhaps the most significant single UAP incident in American nuclear history.
