Vehicle Interference

Vehicle interference is the specific subset of EM-effect cases involving cars, trucks, and aircraft — engine stalls, radio static, and headlight failures that reliably reverse once the reported object moves away — as opposed to EM effects on fixed installations like power grids. The category is really a description of a highway phenomenon: because so many reports involve isolated rural motorists at night, driving alone or in small groups, vehicle interference cases share a distinctive signature of independently stranded witnesses converging on the same story before comparing notes with each other. Levelland, Texas in 1957 is the defining American case, with numerous separate drivers reporting identical stall-and-recover sequences within a two-hour span. The pattern recurred heavily during the 1965-67 U.S. wave, when vehicle-stall reports became common enough that some investigators began treating them as a signature marker distinguishing "serious" close encounters from routine light sightings. Prosaic explanations offered over the decades include electromagnetic pulse from ball lightning or unusual atmospheric static buildup, momentary alternator or ignition faults coinciding with a frightening light in the sky, or simple driver panic misremembering a routine stall as caused by the object; the counter-argument from investigators is the sheer repetition of the exact same failure-then-recovery sequence across geographically and temporally unconnected witnesses.
