The Coyne Helicopter Incident
A U.S. Army Reserve helicopter crew encountered a grey metallic object that stopped their collision descent - then inexplicably lifted them from 1,700 to 3,500 feet while controls were set for descent. All instruments failed, the magnetic compass never worked again, and ground witnesses corroborated the encounter. The crew testified before the United Nations.
The Coyne Helicopter Incident (1973)
On October 18, 1973, during the massive UFO wave sweeping America, a U.S. Army Reserve UH-1H Huey helicopter encountered an unidentified object near Mansfield, Ohio that defied all explanation. As the crew took evasive action to avoid collision, a cigar-shaped metallic craft stopped directly in front of them, swept a green light through their cabin, and - while the collective was set for descent - somehow lifted the helicopter from 1,700 feet to over 3,500 feet. All instruments failed during the encounter, the magnetic compass never worked again, and a family on the ground independently witnessed the entire event. Captain Lawrence Coyne later testified before the United Nations.

The Flight
Mission
The context:
- UH-1H Huey helicopter
- Returning from Columbus to Cleveland
- Army Reserve training flight
- Night conditions
- Routine mission
Location and Time
When and where:
- October 18, 1973
- Approximately 11:00 PM
- Near Mansfield, Ohio
- Over Charles Mill Lake area
- Clear night
The Encounter
Initial Sighting
First observation:
- Sergeant Yanacsek spotted red light on eastern horizon
- Initially thought conventional aircraft
- Light appeared stationary
- Then began closing at high speed
- Approaching helicopter rapidly
Collision Avoidance
Coyne’s response:
- Light closing on apparent collision course
- Initiated emergency descent
- Dropped from 2,500 feet to 1,700 feet
- Attempted radio contact with Mansfield tower
- Radio completely dead on all frequencies
The Object Arrives
What happened:
- Object stopped directly in front of helicopter
- Hovered above and ahead
- No collision occurred
- Object positioned itself deliberately
The Object
Physical Description
What the crew observed:
- Approximately 60 feet long
- Cigar or cylindrical shape
- Metallic grey structure
- Solid, structured craft
- Not a light or meteor
Lights
Illumination observed:
- Red light at front (bow)
- White light at rear (stern)
- Green light underneath
- Green light swept through cabin
- Illuminated entire helicopter interior
The Green Light
The key moment:
- Green light swept across helicopter
- Filled cabin interior
- Bright enough to illuminate everything
- Crew bathed in green glow
- Extraordinary sight
The Impossible Climb
Controls Set for Descent
The anomaly:
- Collective was in full down position
- Should have been descending
- Instead, helicopter rose
- From 1,700 feet to over 3,500 feet
- Climb rate approximately 1,000 feet per minute
Physical Impossibility
What should have happened:
- Collective down = descent
- Cannot climb with collective down
- Fundamental helicopter physics violated
- Something lifted them
- Against their control inputs
Duration
How long:
- Climb continued for approximately 1-2 minutes
- Crew noted altimeter climbing
- Despite descent configuration
- Coyne finally noticed altitude gain
- Regained control only after object departed
Instrument Failures
Complete Shutdown
Systems affected:
- All instruments malfunctioned
- Magnetic compass spinning wildly
- Radio dead on all frequencies
- No communications possible
- Total electrical disruption
Radio Failure
Communication blackout:
- Attempted contact with Mansfield tower
- Complete silence
- No static even
- Dead radio
- Restored only after object left
Permanent Damage
The compass:
- Magnetic compass never worked again after encounter
- Had to be completely replaced
- Could not be repaired
- Permanent physical evidence
- Something affected it fundamentally
Object Departure
Exit
How it left:
- After brief hover, object accelerated westward
- Disappeared over horizon
- Extreme speed
- No sonic boom
- Gone in seconds
Systems Restoration
Recovery:
- Instruments gradually returned to normal
- Radio came back
- Except magnetic compass
- Helicopter controllable again
- Normal flight resumed
Ground Witnesses
The Family
Independent confirmation:
- Mother and children in car below
- Observed both helicopter and object
- Different vantage point
- No connection to crew
- Separate witnesses
Their Description
What they saw:
- “Blimp-like,” “pear-shaped” object
- “Big as a school bus”
- Saw green light illuminate helicopter
- Watched entire encounter
- Corroborated crew’s account
Significance
Why this matters:
- Ground witnesses confirm event
- Not crew hallucination
- Object was visible to others
- Independent verification
- Multiple locations confirm same event
Investigation
Official Reporting
What Coyne did:
- Reported to FAA (P.J. Vollmer, Cleveland Hopkins)
- Filed complete account
- Submitted documentation
- Vollmer statement: “I trust his judgment without a question of a doubt”
NORAD Confirmation
Military verification:
- NORAD confirmed no other aircraft in area
- No traffic that could explain sighting
- Object was not conventional aircraft
- Tracking data supported encounter
- No identification made
CUFOS Investigation
Civilian study:
- Jennie Zeidman conducted extensive investigation
- Interviewed all witnesses
- Documented all evidence
- Published findings
- Case considered among best on record

Analysis
Evidence Quality
Why this case is exceptional:
- Four trained military aviation witnesses
- Ground corroboration

- Physical evidence (compass destroyed)
- No conventional explanation
The Lift
The central mystery:
- Helicopter lifted against controls
- Physical impossibility
- Something exerted force on aircraft
- 1,800 feet of impossible climb
- Defies physics as we know it
Credibility
Why witnesses are believed:
- Military officers
- Experienced aviators
- Police officer among them
- No motive to fabricate
- Careers at stake
The Question
October 18, 1973. Night. Ohio.
Captain Larry Coyne has been flying for 19 years. His crew chief spots a red light. Coming fast. Collision course.
Coyne pushes the collective down. Emergency descent. 2,500 feet. 2,000 feet. 1,700 feet.
He radios Mansfield tower.
Dead. Nothing. No static. No response. Dead radio.
The object stops. Right in front of them. A grey metallic cigar. Sixty feet long. Red light in front. White in back. And underneath…
Green light sweeps through the cabin. Fills everything. The crew is bathed in green.
And then the impossible happens.
The collective is down. Should be descending. Every helicopter pilot knows: collective down, you go down.
They’re going up.
1,700 feet. 2,000 feet. 2,500 feet. 3,000 feet. 3,500 feet.
The altimeter is climbing. The controls say descend. The helicopter is rising.
Something is lifting them.
The object hovers there. Then it accelerates west. Gone in seconds.
Controls work again. Radio comes back. They’re at 3,500 feet. A mile higher than they should be.
The magnetic compass spins uselessly. It will never work again.
On the ground below, a mother and her children saw it all. The helicopter. The object. The green light.
Captain Coyne testifies to the United Nations. He tells them what happened.
Something took control of his aircraft. Lifted it against his inputs. Released them when it was done.
The compass proves something happened. Destroyed by the encounter. Had to be replaced.
The Coyne helicopter incident.
Four military witnesses. Ground confirmation. Instrument failures. Physical evidence.
And an aircraft that climbed when it should have fallen.
Lifted by something.
Still unexplained.
Still impossible.
Still on the record.
