DOE-UAP-D002 — James Tuck Correspondence: Atmospheric Vortices, Ball Lightning, and the Condon Report

Summary

A short correspondence file released in PURSUE Release 02 as DOE-UAP-D002, associated with James L. Tuck, the British-born Los Alamos physicist known for early fusion work (the “Perhapsatron”) and for his serious scientific interest in ball lightning. The file contains a letter from Tuck to the U.S. Army Engineer School at Fort Belvoir, Virginia, and a second, more personal note discussing ball lightning and UFO literature. Personal names are redacted under (b)(6).

This is a low-drama but genuinely interesting document: it shows a credentialed Los Alamos physicist treating anomalous atmospheric phenomena as a legitimate object of study, and explicitly engaging with the Condon Report — the 1968 University of Colorado study that officially closed the Air Force’s UFO investigation (Project Blue Book).

Verbatim — The Fort Belvoir Letter

“As agreed in our telephone conversation of today’s date, I would like to have the recipe that was used for the simulated atomic bomb [demonstrations]. We are interested in the large atmospheric vortices which are produced as reported in the book ‘Scientific Study of Unidentified Flying Objects’ by Dr. Edward U. Condon.”

The reference is to the Condon Report (formally Scientific Study of Unidentified Flying Objects, 1968), directed by physicist Edward U. Condon. Tuck’s interest is in the large vortex phenomena discussed in that study and apparently producible via the “recipe” used in simulated-atomic-bomb demonstrations.

Verbatim — The Ball-Lightning Note

“Mindful of your interesting report on ball lightning, I am enclosing comments on same by a UFO believer, James M. McCampbell, in his UFOLOGY, 1976, appearing on the new non-fiction shelf at the Mesa Library, call number 629.1338 … His chapter FLIGHT AND PROPULSION strengthens my conviction that Einstein, while seemingly straying from the main current of physical research in his later years, was on scent like a bloodhound when he persisted in trying to lock in on a unified field theory.”

The McCampbell reference (UFOLOGY, 1976) dates the note to 1976 or later.

Why This Document Matters

A working physicist took the phenomenology seriously. Tuck was a real Los Alamos figure, not a fringe correspondent. The file documents a scientist at the nuclear lab pursuing atmospheric-vortex and ball-lightning explanations for anomalous aerial reports — engaging the literature (Condon, McCampbell) rather than dismissing it.
It belongs to the Los Alamos cluster in this release. Together with the Sandia green fireball file and the Pajarito Astronomers newsletter, DOE-UAP-D002 shows the New Mexico nuclear-science community as a recurring locus of UFO interest across three decades.
The “natural-phenomenon” hypothesis, from the inside. Tuck’s vortex/ball-lightning framing is the credible skeptical-but-curious position: some anomalous reports may be exotic but mundane plasma/atmospheric effects. That is exactly the kind of hypothesis the green fireball investigators debated.

Caveats

This is light material. It is correspondence reflecting one scientist’s curiosity, not an incident report or a sighting. It documents interest, not an event.
Names are redacted (b)(6), so the recipients and the full chain are unclear.
Attribution to James L. Tuck rests on the OCR’d signature (“James L. Tuck”) and the document’s filing; the signature block is partially degraded.
“James M. McCampbell” is correctly an aerospace engineer and UFO author (UFOLOGY, 1976); the OCR renders the middle initial inconsistently.

Open Questions

What was the “recipe … used for the simulated atomic bomb demonstrations,” and what vortex phenomenon was Tuck trying to reproduce?
Who were the redacted correspondents at Fort Belvoir’s Department of Mechanical and Technical Equipment?
Why was a 1976-era physicist’s UFO/ball-lightning correspondence retained and surfaced in a 2026 DOE UAP release?
