Close Encounter II at Echo Flight: The Unresolved 1967 Malmstrom Missile No-Go

To the point

March 1967 at Malmstrom AFB, guards and missile crews reported a saucer-shaped UFO near Echo Flight as ten Minuteman missiles went from Alert to No-Go, with witnesses like Robert Salas describing a craft hovering over the gate and jerky 90-degree maneuvers and one guard being injured; no official explanation was released at the time, FOIA inquiries later noted a loss of strategic alert and concern at SAC, corroborated by Jim Klotz and others, while Boeing engineers found no definitive cause, leaving the episode unresolved and suggesting secrecy around possible national-security implications despite the Air Force's denial.
