HISTORICAL

Coyne helicopter incident — An Army Reserve UH-1 helicopter crew over Mansfield, Ohio encountered a cigar-shaped craft that appeared to control the helicopter's altitude. Captain Lawrence Coyne reported the event to the FAA.

On the night of October 18, 1973, four members of the US Army Reserve aboard a Bell UH-1 Huey helicopter encountered a cigar-shaped object near Mansfield, Ohio, that reportedly stopped the helicopter's descent and pulled it upward by some unknown means. The case became one of the most credible 1970s military aviation UFO encounters in the United States. 【Background】 Captain Lawrence Coyne, in command, was returning from a routine medical flight from Columbus to the Cleveland Hopkins reserve base. The crew of four were experienced Army aviators flying at about 2,500 feet over rural Ohio. Visibility was clear under a moonless sky around 11 p.m. 【The Encounter】 Crew chief Sergeant John Healey first spotted a red light to the east, then on the southern horizon. Within seconds, the object closed on the Huey at high speed on a collision course. Coyne pushed the collective down to dive from 2,500 to 1,700 feet at about 2,000 feet per minute. The object then stopped directly above the helicopter; a green beam swung down through the windshield and into the cockpit. The magnetic compass spun continuously. Despite the controls still being set for descent, the altimeter showed the helicopter rising back to 3,500 feet. 【Investigation】 The case was studied by Jennie Zeidman of the Center for UFO Studies (CUFOS), who interviewed all four crew members and ground witnesses on the road below who independently reported the same object. The Army never issued an official conclusion. Skeptics proposed a fireball from the Orionid meteor shower, but the meteor hypothesis cannot account for the object's apparent stop, the cockpit's green illumination, or the altitude gain. 【Modern Assessment】 The Coyne case is repeatedly cited in academic literature on aviation UAP because of its combination of four professional military witnesses, ground witnesses, instrumentation anomalies, and a substantial altitude change of unknown origin. It is included in the Sturrock Panel's 1998 review of physical evidence for unexplained aerial phenomena. Source: https://en.wikipedia.org/wiki/Coyne_helicopter_incident
