Los Alamos
Los Alamos, New Mexico — site of Los Alamos National Laboratory, the Manhattan Project and ongoing U.S. nuclear-weapons R&D center.
UAP relevance: PURSUE Release 02 includes a 1970 handwritten letter from a Los Alamos scientist reporting green lights regularly seen in the mountains between 9 and 11 p.m. during 1948–1951, once “moving in some kind of formation” (src-nbc-pursue-firsthand-encounters-2026-05). The account overlaps the broader 1948–1951 New Mexico green-fireballs wave and the nearby Sandia, New Mexico 1948–1950 sighting cluster, reinforcing the recurring nuclear-site / UAP correlation theme.
PURSUE Release 04 (July 10, 2026) surfaced a primary transcript-level record: a 1949 conference of top physicists and scientists — including Manhattan Project veterans — convened at Los Alamos to explain the green fireballs. They failed to reach consensus; a prominent astronomer rejected the meteor hypothesis (“nothing like this … has ever been observed in the case of meteorite drops”). See src-cbs-pursue-release-04-2026-07 and src-thehill-pursue-release-04-2026-07.
avi-loeb’s July 10, 2026 independent review of the same release (src-loeb-pursue-release-04-2026-07) adds named participants: the conference was organized by edward-teller, with Lincoln LaPaz, lab director Norris Bradbury (who closed the conference conceding the fireballs’ horizontal paths and silence remained unexplained), and future Nobel laureate Fred Reines, plus Army/FBI/AEC/University of New Mexico representatives. Loeb’s account is more equivocal than the CBS/Hill framing: the group considered but did not settle the shallow-meteor-entry hypothesis, rather than flatly rejecting it.
