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 ADDED NORMAL TESTING. A REVIEW OF AVAILABLE DATA STRONGLY SUGGESTS THIS TO BE A WING I PECULIAR PROBLEM. THE OOAHA ETF IS NOT A WING X FACILITY. IT IS THEREFORE, NECESSARY TO RUN THE PROPOSED TESTS AT MALKSTROM, PREFERABLY AT ECHO 8. 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 LP LEVEL. 3. THE FOLLOWING PLAN OF ACTION WAS AGREED UPON BY ALL REPRESENTATIVES. DEVELOP A TEST PLAN WHICH, AFTER ISOLATING AN LF FROM THE SYSTEM, ALLOWS FOR THE APPLICATION OF STIRULI WHICH WILL REFRODUCE THE NO-GO AT THE LF LEVEL. AFTER ANALYSIS OF SUCH TEST DATA, PROCEDING AS REQUIRED TO TEST, CR ANALYZE AT THE LOF 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 REVIEWED FOR SAFETY. THE PLAN WILL RECEIVE SAFETY CLEARANCE THROUGH OONE, 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 HRA FACILITY AT BOEING. 4. ADDITIONAL INVESTIGATIVE ENGINEERING STUDIES ARE IN PROCESS, AND WILL CONTINUE. BOEING IS ATTENTING TO OBTAIN AN EXHIBIT 7KVA TRANS- FORMER WHICH WAS REPORTED TO HAVE SHORTED A FEW HOURS AFTER THE INCIDENT. A TRARDONE REPORT ON THE TRANSFORMER WILL BE DEVELOPED BY BOEING ENGINEERING. DEPARTMENT UPON THE ANALYSIS OF THIS TRANSFORMER, AND ITS FAILURE MODE. ADDITIONAL TESTS MAY BE REQUESTED SIMILAR TO THE POWER TESTS RUN ON 23 MARCH 1967; AT MALIGNON WITH THE ADDED TRANSFORMER FAILURE DDE SIMULATION. YOU WILL BE FURTHER ADVISED WITH RESPECT TO THIS ACCEIVITY. 5. CONCURRENCE IN THE USE OF ECHO B FOR TESTING OUTLINED IN PARA THREE (3) IS REQUESTED. WANNING FACTORS AT THIS TIME ARE FOR A PERIOD OF SIX WEEKS BEGINNING 15 MARY 1967. YOU WILL BE ADVISED OF ANY SHIFT IN THESE TARGET DATES. G1-4.
