That must have been after I was there in the mid-late 70s. I didn’t hear of any suicides just before arriving, or while I was there. There weren’t any missile crew suicides among any of the guys I served with and there was one I know of after I left; a squadron ops officer whom I knew from my time there but he had other problems. During my time on squadron wing staff at the old 44th at Ellsworth I had not heard of any either. At least during my time in both places the bulk of crew members were certified stable individuals. At Minot we only had one lieutenant who really was crazy and his nickname was Crazy Mac. Anyone on crew at Minot at the time would recognize who this individual was and thankfully they finally got rid of him. He was the only fellow crewmember who truly made me uneasy.
I never heard of any suicides of crewmembers, at any of the missile wings, but Minot had a reputation for suicides. I can honestly say that I have not run into more people I thought were “just a little crazy” than I did while I was a crewmember, but hey, maybe I was the one who was crazy?
