UFO Reports Involving Vehicle Interference
A Catalogue and Data Analysis
Core Thesis
UFO Reports Involving Vehicle Interference: A Catalogue and Data Analysis is Mark Rodeghier's October 1981 monograph for the Center for UFO Studies, statistically cataloguing 441 worldwide reports of vehicles experiencing engine stalls, electrical failure, or lighting effects during UFO encounters -- drawn from CUFOS's own UFOCAT database and spanning cases from as early as 1909 through 1981 across at least seven countries. This site cites the book directly for two cases: the 1957 Levelland wave, which the book's own case file describes it as using "as a cornerstone example," and the Loch Raven Dam UFO Incident.
About the Author
This site's own Mark Rodeghier key-figures entry credits him with using the 1957 Levelland case as a cornerstone example in this catalogue, calling it "a foundational reference in vehicle-interference research." Born in Hammond, Indiana in 1953, Rodeghier holds a BS in astrophysics from Indiana University and an MA and PhD in sociology from the University of Illinois at Chicago, with a dissertation examining scientific-community attitudes toward SETI research -- academic training in quantitative social-science methods he brought directly to this catalogue's statistical approach.
Rodeghier joined CUFOS in 1974 and became its President and Scientific Director in 1986, a position his own organization's biography indicates he still holds. His career has spanned vehicle-interference research, physical-trace cases, and abduction-experiencer psychology, and he led CUFOS's own investigation into the Roswell incident. Notably, his professional work outside ufology includes serving as a statistical consultant and survey researcher, co-authoring two books on statistics and survey research and acting as principal statistician on more than eighty clinical research papers -- external, verifiable evidence supporting his reputation as a methodologically rigorous, data-driven researcher rather than a purely narrative one.
Historical Context & Origins
The catalogue draws its 441 cases from CUFOS's own UFOCAT database, the organization's computerized case-tracking system, spanning from an early 1909 report of a motorcycle headlamp failure through cases current to the book's 1981 publication, with reports drawn from the United States, England, France, Argentina, Spain, Brazil, and Australia. This breadth positions it as a genuine cross-national statistical survey rather than a regionally limited case list.
The work functions as both a raw case catalogue and a quantitative analysis: it reportedly includes a chart plotting engine-stall frequency against reported distance from the observed object across all 441 cases, and finds the vehicle-interference phenomenon itself heterogeneous rather than uniform -- roughly half of cataloged cases show combined engine and electrical failure, about a quarter show engine failure alone, and others report only headlight or radio effects, with a reported subset of roughly thirty cases involving permanent rather than temporary component damage.
Core Arguments & Key Concepts
The book's central methodological contribution is treating vehicle interference as a phenomenon amenable to statistical description across a large case sample, rather than relying on any single dramatic incident to carry the evidentiary weight -- a data-first approach consistent with Rodeghier's own sociological training.
That approach did not go unchallenged: a 1980 paper by researcher Donald A. Johnson in the Journal of UFO Studies explicitly contested one of Rodeghier's specific conclusions regarding the relationship between witness position and case severity, using an independently compiled 276-case dataset -- a genuine scholarly disagreement this article notes precisely to avoid conflating Johnson's separate findings with Rodeghier's own, since the two datasets and conclusions are distinct works that happened to engage with the same open question.
Key Cases & Evidence Discussed
This site's own Levelland case file documents the November 1957 Texas wave in far greater depth than this catalogue's single-entry treatment, including Congressional testimony from atmospheric physicist James E. McDonald directly rebutting the Air Force's weather explanation and researcher Antonio F. Rullán's exhaustive modern re-investigation forty-two years after the events. Readers wanting that complete record should consult that case file directly.
This site's own Loch Raven Dam UFO Incident case file similarly documents its own vehicle electrical failure and physiological effects on witnesses Cohen and Small in greater depth than this catalogue's statistical entry allows, situating that specific Maryland case within the broader vehicle-interference class this book surveys quantitatively.
Critical Reception & Controversies
As of this article's research (August 2026), this is a niche 1981 research-organization monograph with no Goodreads or Amazon customer reviews and no mainstream press coverage -- an expected pattern for this kind of publication, whose real measure of reception lies in citation rather than consumer reviews.
By that citation measure, the book appears to hold genuine standing: secondary sources describe it as the most frequently cited reference specifically on UFO vehicle and engine interference, and its data -- specifically its chart plotting engine-stall frequency against distance across all 441 cases -- has reportedly been cited by physicist Peter Sturrock, who led the 1998 Society for Scientific Exploration UFO panel, in his own book The UFO Enigma. This article treats that specific citation claim as reported rather than independently page-verified, but notes it alongside Donald Johnson's 1980 direct scholarly engagement with the book's conclusions as evidence the work was taken seriously enough within the field to be built upon and contested rather than simply repeated uncritically.
Influence & Legacy
The book's legacy rests on its function as the standard statistical reference for vehicle-interference cases within ufology research -- a role reinforced by CUFOS's own continued hosting of the complete text as a free PDF download on its current website, keeping the catalogue directly accessible more than four decades after its original publication rather than letting it lapse into out-of-print obscurity.
Set alongside this site's own Levelland and Loch Raven Dam UFO Incident case files, this book remains valuable chiefly as the broader statistical context within which any single vehicle-interference case can be situated, rather than as a source of additional case-specific evidence beyond what its brief catalogue entries provide.

Why This Is Essential Reading
UFO Reports Involving Vehicle Interference earns its place on this reading list as the field's foundational statistical reference on its subject, produced by a researcher whose sociological training and verifiable outside statistical career support its data-driven credibility. Read alongside this site's own Levelland and Loch Raven Dam UFO Incident case files, which supply the fuller, independently sourced record for each specific case, it remains essential as the broader quantitative context against which any single vehicle-interference report can be measured -- and it remains freely readable today directly from CUFOS's own website.
