Conspiracy of Silence

About the Author

Dermot Butler and Carl Nally, both born and raised in Dublin, trace their UFO interest to childhood, and by the mid-1990s were already committee members of an earlier, unnamed Dublin-based paranormal research group before formally co-founding UPRI (UFO and Paranormal Research Ireland) -- a founding date sometimes given as 1998, though this article found that date in only a single source and was not able to independently corroborate it against a second, more authoritative record.

Per the Irish Times, UPRI does not have formal "members" in the traditional sense but roughly thirty "contributors" who fed a quarterly magazine of Irish sighting reports. This article's own research found no evidence either author holds formal scientific, aviation, or professional investigative credentials; both present, across every source consulted, as long-term enthusiast researchers rather than credentialed investigators. Carl Nally has remained publicly active into the current decade, appearing in December 2024 media coverage discussing an "Athlone alien portal" theory -- reporting this article treats as evidence of his continued public profile, not as evidence bearing on this book's own claims.

The two authors followed this book with a second, States of Denial: The Tuskar Rock Incident and Other Mysteries (Mercier Press, 2013), examining the 1968 Aer Lingus Tuskar Rock crash and other cases -- a continuation of the same aviation-incident focus this book's own pilot-encounter material reflects.

Historical Context & Origins

The book's content is organized thematically rather than strictly chronologically, with chapters this article's own research confirms include "Cover-up and conspiracies," "Altered states and abductions," and "Retrieved and analysed alien implants," alongside case material centered on Newgrange and the Boyne Valley -- explicitly tied by the authors to megalithic and summer-solstice theorizing -- plus Boyle, Bantry, Cork, Wicklow, and Roscommon.

The title's own "conspiracy of silence" is best understood, per a 2007 review this article located, less as a claim of a proven documentary cover-up and more as a broader argument about Irish cultural reluctance to discuss UFO experiences openly, in contrast to the culture's greater comfort discussing religious apparitions. The authors' own rhetoric elsewhere -- including Nally's public calls for Irish government document releases comparable to France, Germany, and the UK -- does frame the silence as partly institutional as well. This article found no independently documented case of a specific Irish Air Corps or air-traffic-control cover-up; that framing should be understood as the authors' own allegation rather than an independently verified fact.

Core Arguments & Key Concepts

The book's implicit argument treats Irish UFO reports as a genuine, under-examined body of evidence deserving the same documentary treatment given to national UFO histories elsewhere, compiled primarily from UPRI's own case files and contemporary newspaper coverage rather than government archives, which Ireland's smaller and less centralized defense and aviation bureaucracy has not released in comparable volume to the UK's Ministry of Defence files.

This article's own research surfaced a specific, credible critique of that evidentiary approach worth stating plainly rather than glossing over: Dr. David Clarke -- the UK academic (Sheffield Hallam University) who served as the official consultant and curator for the Ministry of Defence's own UFO-file release project with The National Archives (2008-2013) -- reviewed the authors' 2013 follow-up book for Magonia and reported that Timothy Good, the British UFO researcher whose cover blurb calls this earlier book "a ground breaking book," separately found the underlying pilot-sighting stories "hard to believe" because Butler and Nally "had never actually spoken to the pilots concerned." Clarke's own review further describes the authors relying on uncorroborated, anonymous sources and treating official denials as further evidence of cover-up rather than grounds for doubt -- a pattern this article flags as directly relevant given this site cites the book on a case file built around specific airline pilot reports.

Key Cases & Evidence Discussed

This site's own 2018 Irish Airspace UFO Sightings case file (Case File #187) documents the November 2018 wave of pilot reports -- including British Airways and Virgin Atlantic crews -- of fast-moving bright objects over Irish airspace near Shannon in far greater depth than this 2006 book, which predates that specific incident by more than a decade, could possibly cover. The case file cites this book only for broader historical and cultural context on Ireland's own thinly documented sighting history, not for any direct coverage of the 2018 case itself.

This article's own research was not able to identify any single named case within this book with the same evidentiary weight as the 2018 Shannon reports -- consistent with the book's own "thumb-nail sketch" survey format, compiling many brief case summaries rather than a small number of deeply investigated incidents.

This site's own The UFOs That Never Were essential-reading entry covers a separate book by Dr. David Clarke, the same researcher whose Magonia review supplies this article's central critique of Butler and Nally's pilot-witness methodology -- useful comparative reading from the more skeptical, archive-driven end of British and Irish UFO research.

Critical Reception & Controversies

As of this article's research (August 2026), the book holds a 4.38-out-of-5 average on Goodreads, but from only 8 ratings and zero written reviews -- too small and thin a sample to draw any real conclusion from.

The two substantive critical treatments this article located were both skeptical rather than credulous. A 2007 review called the book "an indispensable example of contemporary folklore at work" as a cultural document, while separately concluding the authors' "allegations fail to convince" and noting production sloppiness, including a recycled advertisement reused within the book. Dr. David Clarke's 2013 Magonia review, discussed above, is considerably more pointed: it directly disputes the authors' pilot-witness methodology and notes that no passenger has ever corroborated any of the claimed pilot encounters despite media coverage.

This article found no evidence of citation or engagement with this book by academic UFO historians or by more methodologically rigorous researchers, beyond the two skeptical treatments above -- a pattern consistent with a book whose value lies chiefly in being the only substantial book-length survey of its specific national subject, rather than in any particular case being independently well-corroborated.

Influence & Legacy

The book's legacy rests almost entirely on its lack of competition: this article's own research found no other book-length survey specifically of Irish UFO history, making this title the default reference on the subject by default rather than by any demonstrated rigor -- a distinction this site's own case-file citation already implicitly acknowledges by describing it as the "primary" survey rather than an authoritative one.

Set alongside this site's own 2018 Irish Airspace UFO Sightings case file, this book remains useful chiefly for general Irish cultural and historical context -- not as a source of independently verified pilot-witness evidence, given the specific, credentialed critique of the authors' pilot-interview methodology detailed above.
