Summary
116 pages of documentation from the Armed Forces Special Weapons Program (AFSWP — the direct post-World War II successor to the Manhattan Project) and the U.S. Air Force, covering a series of UAP sightings and investigations at Sandia Base, New Mexico from 1948-1950. The file contains 209 documented sightings of green orbs, discs, and fireballs reported near the military base. Witnesses describe UAP maneuvering, flying out of sight, disappearing, and exploding. Contemporary investigations documented residual copper powder at sighting sites — the only physical trace evidence in any PURSUE document to date. Several of these investigations formed the direct foundation for Project Grudge.
Significance
DOW-UAP-D017 is the most evidentiary document in PURSUE Release 2. It contains the largest single count of documented UAP sightings of any released document (209), the only physical trace evidence (copper powder residue), and the only direct connection to the founding of a major UAP investigation program (Project Grudge). The AFSWP origin is critically significant: this is the nuclear weapons security organization — the direct successor to the Manhattan Project — formally documenting UAP at the Sandia/Albuquerque nuclear weapons complex.
