Partin also provides the curious recollection that at about the same time as the B-52 overflight of the UFO, “the Air Police [missile security personnel] saw something in the same vicinity and then they heard this I believe they phrased it as a 60-cycle per second hum I guess, like electric motors or something. Of course, we could hear nothing where we were. And then all of a sudden it was gone” (2001, 3).
