UFOs, Nuclear Sites & Los Alamos: 8 Declassified UFO Files

On 16 February 1949 scientists met in a Secret conference at Los Alamos to discuss green fireballs first reported by airline pilots in December 1948. A 1949 Air Force study noted sightings near Oak Ridge and the Hanford Works, and in 1952 Ruppelt described report concentrations around Los Alamos and Albuquerque. In September 2015, ground radar at the Pantex Plant near Amarillo, Texas, tracked an unknown object that security officers followed until it was no longer visible.

Where the lore differs: Popular accounts read sightings near atomic plants as alien interest; the 1949 Air Force study weighed sightings near Oak Ridge and Hanford as possible Soviet photographic reconnaissance.

What stands out

This bundle strings together Cold‑War era briefings, a 2015 radar sighting, and a few bureaucratic love letters about mysterious lights. It’s a cross‑section of how seriously (or not) the government pretended to take UFOs near its nukes.

  1. DOW-UAP-D094 — Analysis of Flying Object Incidents in the United States, 1949 — 1949 Air Intelligence Report tallies ~210 sightings by pilots and weather pros—because even the guys who forecast rain love a good mystery.
  2. DOW-UAP-D154 — Transcript of a Presentation by Captain Edward J. Ruppelt, 1952 — 1952 Ruppelt transcript reveals 20% of 800 cases stayed unexplained—proof that the Air Force could budget mystery minutes into meetings.
  3. DOE-UAP-D005 — Pantex Unidentified Object Incident Report, 2015 — 2015 Pantex radar log notes a silent, propulsion‑less object cruising west—turns out even top‑secret plants get ghost‑drivers on their screens.
  4. DOE-UAP-D004 — Los Alamos Conference on Aerial Phenomena, 1949 — 1949 Los Alamos conference minutes discuss green fireballs, showing that nuclear scientists debated UFOs before they could agree on particle physics.
  5. FBI-UAP-D011 — D/FBI Correspondence Referral, 1949 — 1949 Hoover‑directed letter details four beams over the Cascades, because even the FBI needed a celestial light show for morale.
