Ellsworth Delta-3 Diamond-Object / Power-Loss Incident
A week or two after Christmas 1978; Mills also described it as late December 1978 or early January 1979Ellsworth AFB Minuteman missile field, South Dakota, South Dakota, United States
John W. Mills III told Hastings that during an RMAD targeting procedure at Delta-3, a low-frequency hum and a large dark four-sided object were present over the site. The site, vehicle and radio then lost function; power later returned and the object was gone. Mills said another Echo targeting team described a similar event, while a wider 12–13 missile outage was learned second-hand.
