Background of the 1973 Coyne Helicopter UFO Incident
On October 18, 1973, a U.S. Army Reserve UH-1H helicopter crew had an encounter that quickly became one of the most discussed UFO cases in American history. The flight, which involved routine military personnel, is notable for its multiple credible eyewitnesses and well-documented sequence of events.
Setting and Timeline
The encounter took place over northern Ohio, with the helicopter originating from the Cleveland area and headed toward Columbus. The crew was flying at night, returning from a routine medical evaluation at the 316th Medical Detachment based in Cleveland. Their course took them near Mansfield, with the Charles Mill Reservoir and Galion also falling along the path.
At approximately 11:00 p.m., while the UH-1H “Huey” helicopter was near Mansfield, the crew observed a red light approaching from the west, moving rapidly. The object, which appeared near Lake Erie, rapidly closed the distance, eventually resulting in a close encounter over Charles Mill Reservoir. The incident lasted little more than five minutes but included dramatic maneuvers and unexplained interference with the helicopter’s controls.
Key Personnel and Military Involvement
The helicopter crew consisted of four Army Reserve personnel: Captain Lawrence J. Coyne (pilot and unit commander), First Lieutenant Arrigo Jezzi (co-pilot), Sergeant John Healey (flight medic), and Sergeant Robert Yanacsek (crew chief). All were part of the 316th Medical Detachment, a unit with direct links to the U.S. Army Reserve.
Coyne, an experienced army reserve helicopter pilot, was at the controls during the incident. His crew, each with distinct military roles, gave separate but consistent accounts of the event. The incident drew the attention of Air National Guard units and various UFO investigators due to the disciplined military context and the reliability of the witnesses involved. The specifics provided by the crew, along with the helicopter’s direct flight path between established bases, played a significant role in later assessments of the case.
Flight Path and Sequence of Events
On October 18, 1973, a U.S. Army Reserve helicopter experienced a series of unusual and significant flight events over north central Ohio. The crew’s routine journey was interrupted by a startling encounter with an unidentified flying object, leading to a rapid chain of cockpit maneuvers and system anomalies.
Pre-Encounter Flight Details
The helicopter, a UH-1H Huey, departed from Port Columbus around 10:30 p.m. The crew consisted of Captain Lawrence Coyne, First Lieutenant Arrigo Jezzi, Sergeant John Healey, and Sergeant Robert Yanacsek.
They were returning from flight training, following a southwest heading toward Cleveland. The aircraft was cruising at about 2,500 feet.
Radio contact was normal, and navigation was supported by both visual ground references and instruments. Weather conditions were described as clear to partly cloudy, allowing for normal flight operations. The cockpit was operating smoothly, and all crew members were alert and engaged in standard procedures.
Initial Encounter with the UFO
While flying west of Mansfield near Charles Mill Lake, the crew observed unusual lights in the sky.
Sergeant Yanacsek, seated in the right rear, was first to notice a single red light approaching from the southeast. Shortly after, other crew members spotted white and green lights associated with the object, each reporting their positions in the cockpit as they tracked the source.
The object appeared to be moving steadily at about 50 mph, maintaining a constant altitude. The crew initially believed it might be an aircraft, but its lights and behavior did not match typical navigation or aircraft light patterns. The object then began a rapid descent, closing distance with the helicopter at an unexpected rate.
Close Encounter and Collision Course
As the UFO drew closer, it seemed to enter a direct collision course with the helicopter. Captain Coyne immediately initiated a controlled powered descent to avoid impact, lowering the collective and noting a rapid drop in altitude on the altimeter.
The cockpit illuminated from a brilliant white light that bathed both the helicopter and crew. Crew members reported that during this close encounter, the aircraft’s magnetic compass began to spin uncontrollably. Instruments behaved erratically, and radio contact was briefly lost.
For several seconds, the object maintained a hovering relationship above and slightly ahead of the helicopter. The close proximity and intense lights—a combination of brilliant white and bright red, with a distinct green source—made the outline of the object clearly visible from the cockpit.
Post-Encounter Maneuvers and Recovery
Following the near miss, the UFO departed rapidly towards the west, leaving the crew momentarily stunned. Captain Coyne realized that despite attempting a powered descent, the helicopter had inexplicably gained more than 3,500 feet in altitude, as indicated by the altimeter.
Systems returned to normal function: the magnetic compass stabilized, and radio contact was reestablished. The crew regained control and confirmed no injuries or damage to the aircraft. After this incident, the flight proceeded to its intended destination with the crew continuing to monitor all cockpit instruments closely.
Later analysis and debriefings highlighted the brief period of uncontrolled ascent and system anomalies as unexplained, underscoring the extraordinary nature of this close encounter and near midair collision.
Description of the Unidentified Object
Eyewitnesses described several distinctive features of the unidentified flying object encountered during the Coyne Incident. Key aspects include its overall shape, surface details, and striking visual effects involving lights and color.
Shape and Appearance
The object was described as cigar-shaped, a common term for elongated aircraft seen in many UFO reports. According to the flight crew, its approximate length was estimated to be about 60 feet, making it much larger than a standard helicopter or small plane.
Witnesses agreed that the object looked like a blimp or a high-performance aircraft without wings or any visible means of propulsion. Its surface appeared smooth and metallic, lacking any markings or typical aviation lights. No windows, doors, or external features such as rotors were reported.
From a distance, it appeared solid and symmetrical, with no irregular outlines. The craft hovered silently above and maneuvered with precision, exhibiting flight characteristics inconsistent with conventional aircraft of the time.
Lights and Visual Characteristics
One of the most notable aspects was the brilliant white light that shone from the front of the object. This light was intense and well-defined, momentarily illuminating the helicopter cockpit and the surrounding area. In addition, a red light was visible at one end of the object, first mistaken for a warning or navigation light.
The UFO emitted a green beam that shone directly at the Army Reserve helicopter. This green light was concentrated, bright, and appeared to track the helicopter’s movements as the incident unfolded.
Eyewitnesses emphasized the difference between the light from this craft and ordinary aircraft lighting: the UFO’s lights were both brighter and uniquely colored. There was no sound accompanying the illumination, and the effect left a lasting impression on those involved.
Witnesses and Testimonies
Numerous eyewitnesses gave first-hand accounts that became vital documentation for the 1973 Coyne Incident. Both the helicopter crew and individuals on the ground provided statements that were later examined by investigators.
Helicopter Crew Statements
The helicopter crew included Capt. Larry Coyne, First Lieutenant Arrigo Jezzi, Sergeant Robert Yanacsek, and another crewman. Each crew member reported encountering a large, gray, cigar-shaped object with a bright red light while flying over Charles Mill Lake on October 18, 1973.
Capt. Coyne described how the object approached rapidly, stopped in midair, and hovered above the helicopter. He noted a green beam that appeared to envelop the aircraft, causing controls to become unresponsive for a brief period. The crew’s detailed statements were consistent, and they recorded the incident immediately upon landing.
Sergeant Yanacsek specifically recalled the craft's unusual maneuvering and the sensation of an unexplained “lift” that seemed to pull the helicopter upward. First Lieutenant Jezzi confirmed the unusual magnetic readings noted during the encounter. The credibility of these testimonies was supported by their military roles and technical backgrounds.

Witnesses noted a glowing red light in the sky, along with a hovering craft that appeared to interact with the helicopter. Their statements matched the timeframe and sequence reported by the crew, further validating the occurrence. These independent accounts were collected by local authorities and civilian UFO researchers.
Some observers experienced feelings of confusion and alarm as they watched the event. The consistency between ground and air testimonies added to the case’s credibility and continues to draw attention from UFO investigators.
Official Investigation and Reports
The Coyne Incident received significant attention from both government agencies and the media immediately after it occurred. The credibility of involved witnesses and the documented chain of events led multiple authorities and researchers to take the case seriously.
FAA and Military Documentation
Following the incident, the Federal Aviation Administration (FAA) required a formal report from Captain Larry Coyne and his crew. The U.S. Army also conducted interviews and reviewed flight records. All four crew members submitted written statements, describing a metallic, cigar-shaped object that approached the helicopter and exhibited flight characteristics they could not explain.
The incident was listed in official military flight logs, and the Army helicopter’s flight path and communications were investigated. No known aircraft matched the description or location in the area that night. Requests under the Freedom of Information Act have confirmed that government and military documentation exists for this case, making it one of the more reliable UFO sightings on record.
Media Coverage and Public Response
The incident attracted widespread media coverage across Ohio and nationally. Newspapers detailed the crew’s accounts, often highlighting the involvement of trained military personnel and the lack of a straightforward explanation. Television broadcasts and radio shows interviewed the witnesses and brought in UFO researchers, including representatives from groups like the Center for UFO Studies.
These reports helped shape public perception, with the Coyne Incident rapidly becoming one of the best-documented and most credible UFO cases of the 1970s. Skeptics such as Philip Klass also analyzed the case, critiquing details and proposing alternative explanations, but no conclusive debunking emerged. Interest from both the public and investigators contributed to the case’s lasting prominence.
Analysis and Theories
The Coyne case has sparked debate among investigators, with perspectives ranging from mundane explanations to support for an unidentified flying object. Proposals for the object’s identity include natural phenomena, military aircraft, and genuine UFO encounters.
Skeptical Explanations
Skeptics have put forward several theories to explain the 1973 incident. One suggestion is that the crew witnessed a meteor, possibly a fireball from the Orionid meteor shower, which occurred around the same date. Some have also speculated about the possibility of a high-performance aircraft, such as F-100 Super Sabre jets, being responsible.
Others have considered a blimp or a civilian or military helicopter as possible sources. However, reports noted that no scheduled air traffic was in the area at the time. Critics highlight that stress, optical illusions, or misidentification under challenging night flying conditions could cause perception errors.
Reference charts, such as this comparison, are used in investigations:
Theory Plausibility Evidence Noted Meteor/Fireball Moderate Orionid shower Military Aircraft Low No tracks reported Blimp/Helicopter Low No matching flights
Skeptics emphasize the limitations of eyewitness testimony, especially during moments of surprise or stress, and find no direct evidence linking the sighting to an unknown craft.
Support for the UFO Hypothesis
Proponents of the UFO hypothesis point to several aspects of the Coyne case that set it apart from typical misidentifications. The flight crew, trained in observation and aircraft identification, described an object performing maneuvers beyond known capabilities of blimps or conventional aircraft.
Notably, the object was reported to hover and accelerate at high speed, affecting the helicopter’s instrumentation. No conventional high-performance aircraft or F-100 Super Sabre jets were logged in the area at that time, according to FAA and military records.
The encounter was corroborated by independent witnesses on the ground. The helicopter crew’s consistent accounts—detailing a cigar-shaped object with unusual lighting—remain central for advocates of the unidentified flying objects hypothesis.
Supporters argue that the absence of prosaic explanations favors the UFO hypothesis. The incident is cited as one of the most credible UFO encounters due to the professionalism and number of witnesses involved.
Legacy and Cultural Impact
The Coyne Incident stands out due to the credibility of the witnesses and the detailed documentation by multiple parties. Its influence spread across UFO research, official investigations, and popular discussion for decades.
