Project Blue Book Case #955. On August 25, 1951, a luminous object was observed over Albuquerque, New Mexico — the third Blue Book unknown from this nuclear weapons hub (following Cases #642 from 1950 and #2249 from 1952). Albuquerque's continued production of unknowns reinforced the troubling correlation between nuclear facilities and UFO activity.
The August 1951 sighting coincided with a period of intense activity in the New Mexico nuclear corridor. The green fireball phenomenon continued intermittently, and the Air Force's Project Twinkle was still attempting to photograph the mysterious objects. The Albuquerque area — with Kirtland AFB, Sandia Labs, and Manzano nuclear storage — remained one of the most sensitive and closely monitored airspaces in the country.
The third Albuquerque unknown established the city as one of Blue Book's most persistent problem locations. The pattern of repeated sightings over the nuclear corridor was impossible to dismiss as coincidence, regardless of one's views on what the objects might be.
The case was classified "Unknown."
