Bluegill Triple Prime

Bluegill Triple Prime was a United States high-altitude nuclear test in Operation Fishbowl, the high-altitude series within Operation Dominic. A Thor missile launched from Johnston Island in the central Pacific carried a W50 warhead that detonated about 48 kilometers (30 miles) above the island at 09:59:48 UTC on October 26, 1962, just before midnight local time on October 25 and at the height of the Cuban Missile Crisis. It was the fourth try at the shot: Bluegill was destroyed in flight in June after radar lost track of the missile, Bluegill Prime caught fire on the pad in July and spread radioactive contamination across the launch area, and Bluegill Double Prime was destroyed after it began tumbling on October 15. The yield was officially described as submegaton, and a declassified federal report gives 200 kilotons. Its electromagnetic-pulse measurements supported theory still in use, and two servicemen on Johnston Island suffered retinal damage because their protective goggles were not in place.

The test entered UFO discussion decades later. In 2016, musician Tom DeLonge said on the radio program Fade to Black that something had been brought down during the Cuban Missile Crisis, without naming a test. From late 2024, Australian researcher Geoff Cruickshank built that hint into a detailed theory: that declassified test films show an object tumbling out of the fireball, that a white triangle on one film is a redaction, that Navy deck logs from October 26 to 31 record a recovery operation, and that high radiation-badge readings aboard the USNS Point Barrow point to contact with material from the blast. He set out the case in Liberation Times and on NewsNation.

The story gained wider attention through Harald Malmgren, a trade official who served as deputy special representative for trade negotiations in the 1970s. In posts on X in 2024 and in an interview with Jesse Michels recorded in early 2025, shortly before his death that February, Malmgren said he had held an Atomic Energy Commission Q clearance and had investigated, for President Kennedy, an object brought down by an American nuclear test in October 1962. As journalist Douglas Dean Johnson summarized the account, Malmgren said he was briefed at Los Alamos in November 1962 by the commission's regional director and handled debris from the object. Michels returned to the case in August 2026 with retired Rear Admiral Tim Gallaudet, whose interview was promoted as setting out his personal conviction that something anomalous was recovered from the test.

Johnson, who examined the films, ship logs and test reports in a May 2025 analysis, concluded that no UFO event occurred. He identified the falling object as most likely the 65-foot Thor booster, citing a 1964 report that described it as "a small white dot some distance below the burst." He cited nuclear historian Alex Wellerstein and film specialist Peter Kuran, who judged the white triangle part of the original footage rather than a later redaction. Johnson found nothing in the deck logs suggesting crews regarded recovered objects as exotic, and noted that the Point Barrow was one of 16 ships whose crew badges showed implausibly high readings, which the test report attributed to faulty film-pack seals. He called DeLonge's remarks "internally contradictory and entirely lacking in evidence or sourcing," and noted that Cruickshank himself surmised DeLonge had conflated Bluegill with the July 1962 Starfish Prime test.

Malmgren's own account has fared worse. Johnson's separate May 2025 investigation, drawing on declassified FBI background reports and job applications Malmgren signed, found that he joined the Institute for Defense Analyses as an economist in July 1962 and that the records showed no Atomic Energy Commission clearance; in an August 2026 update, Johnson reported that the National Nuclear Security Administration said Malmgren never held a Department of Energy access authorization. Johnson wrote that discrediting Malmgren "does not disprove Cruickshank's theory." No official record released so far describes an object brought down by the test or a recovered craft.
