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.

TO RESOLVE THIS PROBLEM, OR TO DEFINITIZE ADEQUATE ENGINEERING ANALYSIS TASKS WITHOUT ADDITIONAL TESTING. A REVIEW OF AVAILABLE DATA STRONGLY SUGGESTS THIS TO BE A WING I PECULIAR PROBLEM. THE OOAMA ETF IS NOT A WINGI FACILITY. IT IS, THEREFORE, NECESSARY TO RUN THE PROPOSED TESTS AT MALSTROM, PREFERABLY AT ECHO 6. IT IS CURRENTLY BELIVED THAT FRUITFUL DATA WILL NOT EXIST UNTIL SUCH TIME AS THE NO-GO MODE CAN BE REPRODUCED AT LEAST AT THE LF LEVEL. 5. THE FOLLOWING PLAN OF ACTION WAS AGREED UPON BY ALL REPRESENTATIVES DEVELOP A TEST PLAN WHICH, AFTER ISOLATING AN LF FROM THE SYSTEM, ALLO FOR THE APPLICATION OF STIMULI WHICH WILL REPRODUCE THE NO-GO AT THE LF LEVEL. AFTER ANALYSIS OF SUCH TEST DATA, PROCEDING AS REQUIRED TO TEST OR ANALYZE AT THE LCF LEVEL. THE TASK GROUP WILL CONVENE AT BOEING, SEATTLE ON 4 APRIL TO DEVELOP A TEST PLAN AND PROCEDURES. SUCH PLAN WILL INCLUDE EQUIPMENT REQUIREMENTS, LF ISOLATION PROCEDURES, DEFINE TESTS TO BE PREFORMED, AND BE REVISED FOR SAFETY. THE PLAN WILL RECEIVE SMOOTH CLEARANCE THROUGH CONE, AND WILL BE COORDINATED WITH SAC AS REQUIRED. COMPLETION DATE FOR THE PLAN IS AIMED AT 5 MAY 1967. THE PLAN WILL BE DEVELOPED AND PROTOTYPED, AT THE NRA FACILITY AT BOEING. 4. ADDITIONAL INVESTIGATIVE ENGINEERING STUDIES ARE IN PROCESS, AND WILL CONTINUE. BOEING IS ATTENDED TO OBTAIN AN EXHIBIT 7KVA TRANS- 5. CONCURRENT IN THE USE OF ECHO 8 FOR TESTING OUTLINED IN PARA THREE (3) IS REQUESTED.
