Documents / Report
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.

Seely HBTHOD A 'fireball was raportad to have pasaod ovor the general noighborhood of Socorro, Uew Uexi.00 1 at 8:26 p.m. 1 J'uly 241 1949. Impaotment equipment , develop9d in conneation 1a th the sarosol research proJect ot the New Mex1 co School of !lines, was available, and it was decided to make systematic collections ot airborne me.ter - iel. in the hope ot obta1nill8 material that could be associated .-1th the t1reball. For the present report it is suftio1ent to state that the equipnant processed air at the rate ot about J4 11tera per minute , the particles being separated f'rom the air by -impactment against en adhesi'f9-coate~ plate in an air jet.
