About Physical Effects
Physical effect cases are among the most compelling in UFO research because they provide tangible evidence beyond witness testimony. These cases involve measurable effects on vehicles, electronics, human bodies, or the environment.
Common categories include:
- Vehicle Interference: Engines stalling, headlights dimming, batteries draining
- Electromagnetic Effects: Radio/TV static, compass malfunction, electronic failure
- Physiological Effects: Nausea, headaches, skin burns, temporary paralysis
- Ground Traces: Burned vegetation, soil changes, landing impressions
