Mills separately recalled a dark triangular-looking object moving near Ellsworth’s B-52 Alert Pad while personnel were awaiting an SR-71 departure. He later corrected his earlier belief that the event was over the Weapons Storage Area. He also recalled later Flash-priority instructions not to discuss the incident, but no surviving message is presented.
