St. Clair County police light chase

Record summary

What happened Police officers in several jurisdictions reported a large, silent object or triangular arrangement of lights moving across southwestern Illinois before dawn. Dispatch records allowed investigators to reconstruct a route, though descriptions of shape and altitude differed. Evidence Multiple on-duty police witnesses, radio logs and mapped observation times support the case. Explanations considered A blimp or small aircraft seen from different angles, stars and misassociated lights are alternatives; an advertising blimp operating regionally was investigated. What remains uncertain No radar, close photograph or common range estimate demonstrates one huge solid object. Primary source St. Clair County police light chase — Wikipedia
