This Black Vault release contains the Air Force's 2001 response from the 341st Space Wing FOIA office at Malmstrom AFB, Montana, to a request about the 16 March 1967 Echo Flight missile shutdown, with excerpts from 341st Strategic Missile Wing histories covering 1967 to early 1968. The histories say all ten Echo Flight launch facilities lost strategic alert almost simultaneously. Investigators could not find a logical cause and found rumors of UFOs near Echo Flight to be unfounded.

sites were reported to have been subject to a normal controlled shutdown. The only unusual LF events noted were the failure of the secondary door actuator motor at LF, E-2 and the intermittent operation of the diesel generator at LF, E-8. 62 Technial Analysis Division (TAD) personnel inspected LCC, E-1 for loose cable connections and the Electric Surge Arrester (ESA) room for any faults and noted no unusual discrepancies. (U) LCF, E-1 experienced commercial power problems in the early afternoon of 16 Mar 67 which resulted in a burn out of the 10 64 Hp Envirmental Control System (ECS) chiller compressor motor. (U) At approximately 1400 hrs on 16 Mar 67, the 341st SMW was advised that SAC Headquarters had called in OOAMA support for a complete engineering analysis of this problem. OOAMA decided to send a task group to Malstrom for study of the incident at Echo Flight because the problem pertained peculiarly to Wing I. It was also decided to make the studies and tests there because OOAMA was not equipped with Wing I equipment. The task group included personnel from OOAMA, Boeing Company, Autonetics, and 15th AF ; they were to arrive on 17 or 18 61.
