Lawrence Coyne
Coyne described a close encounter between his helicopter and a bright object while flying over Ohio.
Who This Witness Was
Lawrence Coyne was the aircraft commander of a US Army Reserve UH-1H helicopter travelling from Columbus towards Cleveland, Ohio, on the night of 18 October 1973.
The other crew members were:
- First Lieutenant Arrigo Jezzi;
- Sergeant John Healey;
- Sergeant Robert Yanacsek.
Coyne occupied the principal flight-control position and was responsible for responding to the apparent collision threat.
He is the strongest witness to his own aircraft inputs and operational judgement. He is not the sole source for every visual detail because the crew viewed the event from different positions.
What Is Attributable to This Witness
Coyne reported that:
- a red light appeared in the distance;
- it seemed to approach rapidly on a collision course;
- he attempted to contact relevant air-traffic facilities;
- he lowered the collective and entered a steep descent;
- a luminous or metallic cigar-shaped object came near or above the helicopter;
- the object showed red, white and green illumination;
- green light filled the cockpit and illuminated the surrounding area;
- the object appeared to hover or pause;
- the helicopter later climbed despite his belief that he had not commanded the climb;
- the object departed westwards;
- temporary compass or instrument irregularity may have occurred.
His account of the helicopter's response is direct pilot testimony.
The claim that the object physically lifted the aircraft is an inference requiring flight data that are not available.
How the Account Entered the Record
The crew reported the event through military or aviation channels and completed a near-midair-collision or incident form.
Civilian investigators interviewed the four crew members separately or comparatively near the event.
A detailed Center for UFO Studies report preserved:
- witness interviews;
- drawings;
- flight reconstruction;
- discussion of possible ground witnesses.
Coyne later gave public testimony, including a statement associated with a 1978 United Nations meeting.
The near-event records should receive greater weight than later summaries.
Evidence Analysis
Directness and Control Inputs
Coyne directly controlled the helicopter.
He can speak with high relevance about:
- collective and cyclic inputs;
- descent initiation;
- aircraft attitude;
- altitude indications he noticed;
- collision avoidance;
- workload;
- any unusual handling.
The absence of a flight-data recorder prevents independent verification of exact inputs and vertical profile.
Relevant Expertise
Coyne's helicopter-command experience is highly relevant to:
- normal UH-1H behaviour;
- descent and climb response;
- aircraft lighting;
- collision geometry;
- operational risk.
Expertise does not provide reliable range to an unknown night light.
Initial Collision Threat
A light on a near-constant bearing can indicate collision risk.
The apparent rapid approach may result from:
- a genuinely fast object;
- a conventional aircraft;
- an initially distant source becoming brighter;
- observer manoeuvre;
- range misjudgement.
Coyne's evasive action was an appropriate safety response even if the target was later shown to be ordinary.
Object Shape
Coyne described a metallic or grey cigar-shaped body with coloured lights.
The crew's descriptions were broadly overlapping but not identical.
At night, apparent shape can arise from:
- glare around a bright source;
- several lights defining a body;
- a conventional aircraft viewed from an unusual aspect;
- an airship;
- cloud or haze;
- a structured unknown object.
No photograph establishes the form.
Green Illumination
Green light filling the cabin is one of the strongest shared features.
Possible sources include:
- a nearby green navigation or search light;
- a flare;
- reflection inside the helicopter glazing;
- atmospheric scattering;
- a luminous unknown source.
A physical beam directed by the object is not established merely because the illumination was intense.
The Reported Climb
Coyne believed that he remained in a descent configuration but found the helicopter climbing to a higher altitude.
A causal external-lift claim requires reconstruction of:
- collective position;
- rotor RPM;
- engine torque;
- airspeed;
- pitch attitude;
- vertical-speed indication;
- altimeter lag;
- pressure setting;
- translational lift;
- terrain and wind.
A UH-1H can convert forward airspeed and attitude changes into climb. Pilot attention was divided during an apparent collision.
This does not prove that the climb was ordinary. It prevents assigning the cause confidently to the object.
Instrument Reliability
Crew recollection of altimeter and compass behaviour is relevant.
No:
- preserved instrument trace;
- maintenance fault;
- electromagnetic measurement;
- post-flight anomaly
demonstrates an external field effect.
Crew Corroboration
The other three crew members support:
- the approaching light;
- a close unusual source;
- green illumination;
- a departure.
Their evidence is meaningful because of different seating positions.
It is partly dependent because:
- they shared one aircraft;
- they communicated;
- one collision response affected everyone;
- Coyne's actions controlled their geometry.
Ground Witnesses
A family near Mansfield reportedly observed lights and a helicopter.
Their account can support a real external event.
It is less detailed and was collected through civilian investigation. It does not verify the climb mechanism.
Radar and Air-Traffic Evidence
No public radar track confirms the object.
Coyne's attempted communications did not produce a matched conventional aircraft.
The absence of radar limits range and speed analysis.
Conventional Aircraft
A conventional aircraft with red, green and white lights is an obvious candidate.
Strengths
- Standard aviation colours.
- Collision-course geometry.
- Night-time range uncertainty.
- A large aircraft can appear cigar-shaped.
Weaknesses
- No matching flight was identified.
- Crew described hovering or pausing.
- Intense green illumination and near silence were unusual.
- No normal aircraft body or wings were recognised.
Meteor
A bright meteor can appear to approach rapidly and show intense colour.
It is weak for:
- prolonged close presence;
- stationary or hovering phase;
- continued green illumination;
- structured body;
- reported departure.
A meteor could explain only the initial approach if multiple stimuli were involved.
Airship
An airship can be large, slow and quiet.
It could display coloured lights and a cigar shape.
No airship operation was identified, and the rapid apparent approach and departure are difficult if literal.

- External effects are inferred.
What Is Established
- Coyne commanded the helicopter.
- The crew reported an unusual light and close-looking object.
- Coyne initiated an evasive descent.
- Green illumination was reported by multiple crew members.
- The helicopter later gained altitude.
- A near-event report and separate crew interviews exist.
- No radar, photograph or flight-data recording is public.
What Is Not Established
- The object's exact range, dimensions or speed.
- A directed beam.
- Deliberate approach.
- External lifting of the helicopter.
- Electromagnetic interference.
- Extraordinary acceleration.
- The object's technology or origin.
Overall Assessment
We assess Coyne as a high-access and professionally relevant witness to a genuine unusual aviation event.
His prompt account and crew support make the occurrence stronger than a solitary light report.
The evidence is less decisive on the object's physical dimensions and its alleged effect on the helicopter. Unknown night-time range and absent flight data prevent verification of external lift or extraordinary performance.
The case remains unresolved at the source-identification level.
