Phoenix Lights (1997)

The Phoenix Lights (1997) remain one of the most credible mass UFO sightings in history. On March 13, thousands witnessed a mile-wide V-shaped formation of lights moving silently across Arizona's skies. The event lasted hours, with separate phases observed by pilots, police, and then-governor Fife Symington. Despite military claims about flares, witnesses insist the enormous, low-flying craft defied conventional explanation. The case stands out for its scale of witnesses, duration, and the credibility of observers—including military personnel—who described technology far surpassing known aircraft capabilities at the time.
