Fifth Blue Book unknown over Albuquerque's nuclear corridor (1952)

Project Blue Book Case #1233. On May 28, 1952, another unidentified object was observed over Albuquerque, New Mexico — the fifth Blue Book unknown from America's nuclear weapons capital. Albuquerque's Kirtland-Sandia-Manzano complex continued to attract unidentified objects with a persistence that made the nuclear-UFO correlation impossible to dismiss. May 1952 was in the buildup to the great wave. The case was classified "Unknown."
