ANALYSIS SUMMARYThis analysis was prepared by Dr. Elara Voss using publicly available source material. It should be verified against the original source documents.

DOW PURSUE document D017 is a collection of general correspondence and reports from Sandia Base, New Mexico, covering UAP observations from 1948 to 1950. Sandia Base was the primary assembly and storage facility for U.S. nuclear weapons in the immediate post-war period, co-located with what would become Sandia National Laboratories and Kirtland AFB. UAP reports near nuclear facilities in New Mexico during 1948–1950 are historically significant — this period overlaps with Project Sign, the Air Force's first official UFO investigation. The concentration of UAP sightings near U.S. nuclear assets was noted in early Air Force UFO investigation records and congressional UAP testimony. This record was previously classified.
