Declassified 341st SMW unit histories

USAF via The Black Vault · 88 pages · text by OCR

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.

e. Facilities:

(1) "In-House" work on removal of obstacles for helicopter landing pads has been discontinued because of snow and cold weather. Resumption of this work at C-7 is tentatively scheduled for 7 February 1968. Work also remains to be accomplished at C-3 and N-4. Obstacle removal has been completed at G-9, D-3, N-1, C-1 and N-10.

(2) Drafting of the helicopter landing approach plates for Launch facilities has been temporarily discontinued at the suggestion of Headquarters 15th Air Force, with 75% completion, until they determine standard criteria for these plates for all missile bases. Currently available approach plates are adequate for interim operational use.

3. Soft Spots: None

4. Problems/Deficiencies Requiring Higher Headquarters Action: None
