DISCLOSURE / FILELos Alamos Physicist Tuck Chases Green Light Origins
DOE-UAP-D002, James Tuck Correspondence, 1970s
Personal correspondence to and from Los Alamos physicist James L. Tuck documenting 1948-1951 green-light UAP sightings at the New Mexico facility and his 1970s inquiry into atmospheric vortex physics linked to the Condon Report.
Brief
Four pages of redacted correspondence reveal two parallel threads: a respondent's first-hand account of recurring green-light sightings and a five-object daytime formation over Los Alamos between 1948 and 1951, all formally logged by the facility's Protective Force; and physicist James Tuck's outreach to the U.S. Army Engineering School at Fort Belvoir requesting data on simulated atomic-bomb atmospheric vortices as described in the Condon Report. A third letter, dated November 28, cites James McCampbell's UFOLOGY (1976) and its chapter on flight and propulsion as reinforcing conviction that Einstein's unified field theory work was directly relevant to UAP propulsion physics. Pages 3 and 4 survive only as severely OCR-degraded scans, limiting verbatim fidelity for those letters.

Key points
- A correspondent reports recurring green-light sightings at Los Alamos during 1948-1951, typically between 9 and 11 PM, concentrated in the Jemez Mountains adjacent to the facility.p.1
- Green lights were observed weaving in and out of mountain peaks; every incident was reported to Protective Force Headquarters and entered into their logs.p.1
- A separate daytime incident involved five unidentified objects flying in formation from Southeast to Northwest over Los Alamos, witnessed by five or six people including at least one Protective Force member (name redacted under b(6)).p.1
- The correspondent explicitly directs Tuck to the Protective Force logs as the authoritative record for times and dates of all green-light sightings, implying those records exist but are not freely accessible.p.2
- James Tuck wrote to the U.S. Army Engineering School at Fort Belvoir requesting the 'recipe' for simulated atomic bomb demonstrations specifically to study the large atmospheric vortices described in the Condon Report.p.3
- A correspondent cites James McCampbell's UFOLOGY (1976) and its chapter 'FLIGHT AND PROPULSION' as strengthening conviction that Einstein's unified field theory pursuit was on the right track for explaining UAP propulsion.p.4
- McCampbell's UFOLOGY (1976) was available on the non-fiction shelf at what the OCR renders as the 'Mesa Library,' placing UAP literature inside Los Alamos's institutional library system.p.4
Verbatim
I can, however, tell you that during the years 1948 through 1951 several sightings of Green lights were made at Los Alamos. These usually occured during the early part of the night, nine to eleven, and were usually in the Jemez Mountains.
p.1I can recall several instances of green lights weaving in and out of Mountain peaks. This was all reported to the Protective Force Headquarters and should be a matter of record on their logs.
p.1I also recall one instance of five objects flying over Los Alamos in the afternoon. They were flying from Southeast to Northwest and appeared to be flying in formation.
p.1Im sure however, if you can obtain access to the pro Force logs during the above periods that the information can be obtained as to time and dates of the Green light sightings

Most interesting
- The correspondence confirms that Los Alamos's Protective Force maintained an internal log of UAP sightings during the late 1940s and early 1950s — records whose current location and public accessibility remain unaddressed in this file.
- The green-light sightings (1948-1951) overlap chronologically with the height of early Cold War nuclear weapons testing at Los Alamos, placing the phenomena at the most sensitive nuclear facility in the United States during its most active period.
- Tuck approaches UAP from an atmospheric-physics angle — requesting atomic-bomb vortex data from the U.S. Army — rather than from any extraterrestrial hypothesis, suggesting his interest was grounded in conventional physics mechanisms.
- The Condon Report, typically cited as a government effort to debunk UAP, is here used by a Los Alamos physicist as a scientific reference for studying physical phenomena associated with the objects — an inversion of the report's conventional reception.
- Pages 3 and 4 are so severely OCR-degraded that key proper nouns (Tuck's own name, the Fort Belvoir addressee) are only inferrable from context; the underlying documents may yield additional detail if rescanned at higher resolution.
- The Einstein-unified-field-theory framing in the November 28 letter anticipates theoretical threads that would appear decades later in government-funded UAP research programs, suggesting the idea had currency among Los Alamos-adjacent scientists well before modern disclosure.
