UAP Reported at Sandia Base, 1948-1950

U.S. Department of War · 1948 · 116 pages · text by GLM-OCR

This U.S. Department of War release compiles 1949 records tied to Sandia Base, New Mexico. It includes a Sandia Base security inspection reply and a W. D. Crozier letter to Lincoln LaPaz. It also contains Crozier and Seely's report on collecting airborne copper particles after the July 24, 1949 fireball near Socorro, which they judged negative or inconclusive. LaPaz's sixth report on green fireballs disputes parts of that finding, and a Fourth Army report describes unusual lights around the Q Area at Camp Hood, Texas, in 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.

HEADQUARTERS, DETACHMENT D 1100TH USAF SPECIAL REPORTING GROUP Campbell Air Force Base Camp Campbell, Kentucky

333. 1

7 April 1949

SUBJECT: Security Inspection

( )

TO: Commanding General Sandia Base Albuquerque, New Mexico

1. Reference is made to secret letter, your headquarters, dated 1 April 1949, Subject: Security Inspection.

2. a. Guard Orders have been amended directing that the electric gate be closed between 1700 hours until 0700 hours the following day.

b. Locks have replaced the bolts in all inspection access gates in the outer fence.

c. Inspection ports on both bridges are now provided with locks.

d. The final draft of our alert plan has been reviewed and will be published and distributed for study to operating personnel. It is desired to point out that the alert plan is incomplete. A stockpile custodian has not been assigned here; his part in the alert plan has been outlined only. Furthermore, since the 11th Airborne Division is not in place yet, only temporary arrangements for defense have been made. Final form of the overall alert plan will be submitted to your headquarters for approval as soon as conditions will allow. In the interim period, it is felt that the temporary alert plan we have prepared is adequate. A copy of this plan will be dispatched to your headquarters in the near future.

## e. All jeep radios are now installed in jeeps.

f. Although not entirely satisfactory, radio communication with the Camp Campbell Military Police has been in effect for sometime and was in effect at the time of the Security inspection. Permanent arrangements for radio communication with Camp Campbell Military Police are delayed pending the arrival of radio frequency crystals that fit the Military Police net frequency.
