This U.S. Department of War file combines security and green fireball records connected to Sandia Base, New Mexico, from 1949. It holds a 7 April 1949 security inspection reply from Detachment D, 1100th USAF Special Reporting Group, at Camp Campbell. It also holds Dr. Crozier's report on airborne copper particles collected after the July 24, 1949 Socorro fireball and Lincoln LaPaz's sixth report on luminous phenomena, both judged negative or inconclusive. The last part is an interim report on unusual lights seen by security personnel at Camp Hood, Texas, on 6 to 8 March 1949.
From the source: Release of 2026-05-22 Incident: 1948-1950, New Mexico. This file contains 116 pages of documentation from the Armed Forces Special Weapons Program (AFSWP) – the direct, post-World War II successor to the Manhattan Project – and from the U.S. Air Force – relating to a series of sightings and investigations in Sandia, New Mexico, from 1948-1950. This file contains 209 sightings of “green orbs,” “discs,” and “fireballs” reported near the military base. Witnesses reported unidentified anomalous phenomena (UAP) maneuvering, flying out of sight, disappearing, or exploding. The documents also include the results of contemporary investigations into residual copper powder found in some areas where sightings were reported. A few of these investigations became the basis for Project Grudge, which collected reports of unidentified flying objects from various other military installations – also included in this collection.
