Two senior military observers reported watching a black triangular object moving at 1,800mph over a redacted sensitive site in the western US earlier this year. The object, described as resembling a delta-wing drone with a 9-15ft wingspan, vanished silently with no exhaust trail. The report was included in the seventh batch of Pentagon UAP files released Friday under the Trump administration's transparency push. The evidentiary basis is thin. The report contains nine identical images of a canyon with small black triangle shapes crudely superimposed to illustrate the alleged flight path. Greg Eghigian, a Penn State professor and author of a 2024 history of the UFO phenomenon, assessed the images as adding "nothing substantive" to the report itself. There are no photographs, no video, no radar data in the public file. The observers are anonymous, identified only as having "extensive operational experience working alongside government agencies." The location is redacted. The object's classification as a UAP — the term that has replaced UFO in official circles — rests entirely on their testimony that it showed none of the characteristics of conventional military aircraft. The broader pattern matters more than this single report. Friday's release contained fewer than 25 text documents and zero videos or images — a notable decline from earlier tranches that included actual photographs and footage. The releases have become "less frequent" and "noticeably thinner" since Trump's February declaration ordering full disclosure about government UFO knowledge. That February order followed the 2023 congressional testimony of a former intelligence official who alleged successive administrations had covered up knowledge of crashed alien spacecraft. The promise was maximal transparency. The delivery has been incremental document drops with heavy redactions, anonymous sources, and declining volume. The structural dynamic is straightforward: disclosure theater serves political interests without requiring actual revelation. Each release generates headlines and reinforces the narrative of government openness, while redactions, anonymity, and the absence of hard evidence ensure nothing operationally sensitive is compromised. The question is whether the diminishing output reflects genuinely depleted files or a political calculation that the transparency promise has already served its purpose. The 'black triangles' report itself is neither confirmatory nor debunking — it is an anecdote dressed as a document. Without corroborating sensor data, identified witnesses, or unredacted locations, it joins hundreds of similar reports that sustain public fascination while resolving nothing about the underlying question of whether anomalous aerial phenomena represent foreign technology, classified US programs, or something else entirely.
