October 1975; NORAD, Cheyenne Mountain, Colorado
According to an informant I interviewed in 1983 there had been a major incident at NORAD HQ which prompted a Security Option 5 alert and total "lock down" at "the Mountain". We have proof that there were incidents at that time period that, to quote from released documents, "prompted the implementations of a Security Option 3 at our northern tier bases since 27 October." Sightings occurred at Loring AFB, Maine, Wurtsmith AFB, New Hampshire ,and then at Malmstrom AFB, Montana.
