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.
10 August 1949 Dr. L1nooln ~ InDtituta of 'Meteoritics University of New Mexico Albuqu.erquo , N. :t:. Doar l.1ncoln: I a::n lnclos1ng two copies or the report you asked tor, fllld hope that they oerve their purpose. \'lo Jiave mado a preliminary ez:eminntion ot tm elghtaon collact1ona token at nine locatione on my, l!onde.:,• 'l'uesday trip . !lbere was a large number of coppor-boar1ng pe.rtiolee on one eolleoti on (ll-104L) taken on Higm1ay 84, seventeen ·mles north ot E1gl:may 661 and aoa.ttered occas• i onal particles throJJ.ghout the series . The collection teken at tho Blt"lle location imcodi ately' following R- l04L eho'\YD practically no copper. A 1orge l)art of the n - 104L is of a granular mnterial untamiliar to us , and , the copper indioat1ona ori,:.inate principal ly 1n l'lhat are e.pparontl'1 aggregations of finely (ona ..meron) granular material of overall sizes in tho neighborhood of thirty microns. Some cop_per _part! ,lea, hor.- ever, appear to be solid nnd o,Paque. The passage of t-, automobiles while this oollection uas being made is a complicating fe.ctor . It is hard to aee how they mieht he.Ta been a eourco ot coppor , ho,raver , unlean it nao a question of stirring up aoI!lo :trom dust on the -pavement. We intend to do some :1"urther chemi.eal work Tii th theee colloctions , but I doubt if muoh nen relevant information 11111 be obtained. Hy tentative conclusion is that no ~idcspread significant dispersion or copper- bea't'ine; particles ,vas present in tbe atmoaphere in the rc"ion covere.:1 at the timo the eollcct1ons wore made. l,o det1nita statel':lcnt is possible about the one heavy copper collention: it should be prosumod to be of local origin until come evidonee to the contrary ic 'found. ~e route at tho collocting trip included Paatura, Santa noaa. , junc tion of Routes 66 and 84, ond Las ·Ve.:;aa on J!ondey af'ternoon.
