Coyne Helicopter Incident

The Encounter

On the evening of October 18, 1973, a Bell UH-1H Huey helicopter of the United States Army Reserve departed Port Columbus International Airport at approximately 10:30 PM, en route to Cleveland Hopkins Airport. The aircraft carried four crew members: Captain Lawrence J. Coyne (36, pilot with 19 years experience), First Lieutenant Arrigo Jezzi (26, chemical engineer and co-pilot), Sergeant John Healey (35, Cleveland policeman and flight medic), and Sergeant Robert Yanacsek (23, computer technician and crew chief).

At 11 PM, while cruising at 2,500 feet over Charles Mill Lake near Mansfield, Ohio, Sergeant Yanacsek observed a single red light on the southeast horizon. Initially dismissed as a tower beacon or aircraft wing light, the object rapidly changed course and began accelerating directly toward the helicopter on a collision course.

Response and Encounter

Captain Coyne immediately initiated an aggressive descent at 2,000 feet per minute while simultaneously contacting Mansfield National Guard aircraft tower. Contact was established briefly—"This is Mansfield Tower, go ahead Army 1-5-triple-4"—but all subsequent transmissions were lost. The helicopter could not outpace the approaching object despite maximum descent efforts.

Just as the crew braced for collision, the object halted and hovered directly above and in front of the helicopter. All four crew members described an identical phenomenon: a cigar-shaped, gray metallic structure with a slightly domed profile but otherwise featureless exterior. At the nose was a steady red light; at the tail, a white light. From the lower section emanated an intense, pyramid-shaped green beam that filled the entire helicopter cabin with vivid green illumination.

Physical and Instrumental Effects

The encounter caused measurable physical effects. The helicopter's magnetic compass malfunctioned during the incident and required complete replacement by maintenance crews, who were unable to repair the original unit. The helicopter's radio communications were compromised throughout the encounter.

Credibility and Investigation

The Coyne Incident is widely regarded as one of the most credible UFO sightings of the 1973 wave. All four crew members were trained military personnel with technical backgrounds; two crew members independently sketched the object and their drawings were remarkably similar. Numerous ground witnesses in north-central Ohio observed the object and helicopter.

The incident was investigated by NICAP, MUFON, and the Center for UFO Studies, with Dr. J. Allen Hynek conducting a detailed investigation in the spring of 1976. The crew was awarded the National Enquirer Blue Ribbon Panel's $5,000 prize for "the most scientifically valuable report of 1973." Captain Coyne subsequently reported the encounter to national television audiences on the Dick Cavett Show and later presented testimony to the United Nations.

Unresolved Mystery

Despite decades of analysis, no satisfactory conventional explanation has been offered for the encounter. The combination of multiple credible military witnesses, physical instrumentational effects, ground corroboration, and high-strangeness characteristics—particularly the cabin-filling green beam—places the Coyne Incident among the most documented and enigmatic close encounters of its era.
