The Vehicle Interference Effect — 441 Documented Cases of EM Disruption

In 1981, researcher Mark Rodeghier compiled and published a statistical analysis of 441 cases where motor vehicles experienced electromagnetic interference in close proximity to UAP. This database represents one of the most systematic evidence sets in UAP research — measurable, repeatable physical effects documented across hundreds of independent incidents worldwide. THE PATTERN: Across 441 cases spanning decades and continents, vehicles in close proximity to UAP experienced a consistent cluster of electromagnetic effects: engines stalling or dying completely, headlights dimming or failing, radios producing static or going silent, and dashboard instruments malfunctioning. In the vast majority of cases, all systems returned to normal function after the UAP departed — without the driver doing anything. The vehicles simply restarted. THE PHYSICS: The consistency of the effect strongly suggests an electromagnetic field of sufficient intensity to suppress ignition systems and electrical circuits. The automatic recovery after the UAP departs indicates the field moves with the object — it's not permanent damage but active interference. This rules out coincidence, mass hysteria, or mechanical failure. Cars don't spontaneously stop and restart in clusters correlated with visual observations by multiple witnesses. THE STATISTICAL SIGNIFICANCE: 441 independent cases from different countries, decades, and witnesses — all showing the same electromagnetic signature. The probability of this pattern occurring by coincidence is effectively zero. The database demonstrates that UAP produce measurable, consistent physical effects on electromagnetic systems, providing indirect measurement of the energy fields these objects generate. This connects directly to the Condign Report's findings on electromagnetic effects and to the broader pattern of radiation injuries (Cash-Landrum, Colares) and sensor interference documented in military encounters.
