EM Effects

EM effects (electromagnetic effects) are reported interference with electrical or mechanical systems during a close UFO encounter — car engines that stall and won't restart, headlights and radios that die, aircraft avionics that fail, all typically reversing the moment the object departs. The pattern is reported often enough across unrelated cases and decades that it forms its own evidentiary sub-category, distinct from a witness merely describing what they saw, because a stalled engine is at least in principle a testable physical claim rather than a purely visual one. Levelland, Texas in November 1957 is the type case: over roughly two hours, at least ten separate motorists on isolated stretches of highway independently reported their engines and headlights failing as an egg-shaped object passed nearby, then restarting once it left — multiple independent witnesses reporting the identical failure-and-recovery pattern the same night is what elevated Levelland above a single unreliable account. Tehran, 1976 layered EM effects onto a radar-visual case, with Iranian F-4 crews losing weapons and communications systems during their intercept attempt. Skeptics point to ball lightning, atmospheric electrical disturbance, or simple mechanical coincidence timed by a frightened driver's memory; proponents treat the consistency of the reversal pattern — systems failing on approach, recovering on departure — as the harder detail to explain away.
