Coyne Helicopter Incident, Army Crew Encounters Object Over Ohio

A U.S. Army UH-1H helicopter commanded by Captain Lawrence Coyne was flying near Mansfield, Ohio when the crew spotted a grey, cigar-shaped object with a bright green light closing on them at high speed. Coyne initiated a steep descent to avoid collision, but the helicopter was pulled upward from 1,700 feet to 3,500 feet with the collective still in the full-down position. The object then accelerated away. All four crew members filed consistent reports, and ground witnesses independently corroborated the encounter. The case was investigated by the Center for UFO Studies and remains one of the best-documented multi-witness military encounters.
