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.

None of the command and status line monitor fault lights were illuminated. There was no pattern or sequence noted as to the illumination of fault and loss of strategic alert. No flickering or ripple was noted on any of the other status displays. The emergency lights were on (all other lights off) and these lights did not appear to dim. 71 The initial time of the incident, decided by the crew, could be no more than two or three minutes earlier than the official log time of 0845 hours (local). 72 The crew also stated; the LF, E-8 had a channel 26 which indicated it was operating on diesel at the time of fault.
