When a case or a claim turns out to rest on nothing that can be opened today, it leaves the database. It does not disappear without trace: this page says what it was, when it went and why.
Cases
delphos-1971 · 15 October 2026
Delphos (2 November 1971)
No source we could open supports any part of the case. The US releases do not mention Delphos, the National Archives catalogue holds no record of the event, and the soil analyses and photographs the case cited have no address. Project Blue Book had been closed in December 1969, two years before the date the case gave. The scores had nothing to stand on.
coyne-1973 · 15 October 2026
The Coyne Helicopter Incident (18 October 1973)
No source we could open supports any part of the case beyond its date and place. The only mention in the US releases is one paragraph of a magazine article reprinted in NASA correspondence of 1998 (USG-UAP-D001), which names the date, Mansfield, Ohio, and Captain Lawrence Coyne’s helicopter crew, and says nothing of what the crew saw or of the altimeter. The National Archives catalogue holds no record of the event, and the flight report and testimony the case cited have no address. The scores had nothing to stand on.
cash-landrum-1980 · 15 October 2026
Cash–Landrum (29 December 1980)
No source we could open supports the event as the case described it. The only mention in the US releases is a Defense Intelligence Reference Document of 2010 (DOW-UAP-D128), which discusses the witnesses’ reported injuries on the strength of a MUFON journal article of 1981 and unpublished findings, and gives no date, place, object or helicopters. The National Archives catalogue holds no record of the event, and the court file and medical records the case cited have no address. The scores had nothing to stand on.
uss-omaha-2019 · 16 October 2026
USS Omaha (July 2019)
No document we can open names USS Omaha: not the Navy’s FOIA reading room, which holds the logs of other ships off San Diego in July 2019, not releases 01 to 06 of the Department of War, not RG 615 at the National Archives, and not AARO, the ODNI, NASA or the printed congressional hearings. The video that circulates under the ship’s name is known from a leak, and the confirmation of 2021 that Navy personnel took it only from the press. What the documents do hold, drones around other ships off San Diego in those weeks, is now in Off San Diego, July 2019. Release 05 has five recordings titled “Unresolved UAP Report, Pacific Ocean, 2019”, among them DOW-UAP-PR124; their descriptions name no ship and give no date beyond the year. The scores had nothing to stand on.

USS Russell — the “pyramids” (July 2019)
The only explanation of the triangles in a document we can open, given by the Deputy Director of Naval Intelligence to a House intelligence subcommittee on 17 May 2022, names neither a ship nor a date: “U.S. Navy personnel recorded what appears to be triangles, some flashing, recorded several years ago off the coast of the United States” (transcript, p. 16). USS Russell’s deck log for July 2019 is public, and nothing in it mentions triangles; its entries from 21:15 to 22:00 on 15 July are blacked out under “(b)(3) 10 U.S.C. § 130”. The confirmation that Navy personnel took the photographs and videos is known only from the press. The claim about the triangles stays in the claims ledger, and the log is cited in Off San Diego, July 2019. The scores had nothing to stand on.
Claims
belgian-f16-acceleration · 5 October 2026
“F-16 radar recorded accelerations impossible for known technology.”
Our verdict described the F-16 radar recordings and how their tracking filter behaved, but no recording, analysis or official account of them is in the US releases or on any official site we could find. The only sources that can be opened are two later accounts: The National Archives’ summary, which says radar “reportedly” tracked an object, and one sentence in a newspaper article of 2000. The Belgian case remains, rebuilt on those two accounts.
belgian-triangle-photo · 5 October 2026
“The Petit-Rechain photograph shows a triangular craft from the Belgian wave.”
Our verdict rested on an admission in 2011 and a report in 2022, and we could open no source for either. Without them the entry would have been a claim and a verdict with nothing behind the verdict.
delphos-hydrophobic-soil · 15 October 2026
“The Delphos ring soil repelled water for years.”
Withdrawn with the case it belonged to: no laboratory report on the soil can be opened today.
coyne-altitude-gain · 15 October 2026
“The helicopter gained several hundred metres with the collective set to descend.”
Withdrawn with the case it belonged to: no flight report, testimony or other document on the climb can be opened today.
