Mansfield UFO Incident 1973: The Coyne Helicopter Encounter
On October 18, 1973, an Army Reserve helicopter crew over Mansfield, Ohio, encountered a mysterious cigar-shaped UFO with a green beam. Known as the Coyne Incident, it remains one of the most credible UFO cases in history.
Last Updated on August 22, 2025 by Daily News Staff
The Mansfield UFO Incident of 1973 — also known as the Coyne Helicopter Encounter — is one of the most documented and credible UFO sightings ever recorded. Involving trained U.S. Army Reserve pilots, multiple civilian witnesses, and unexplained aircraft behavior, this case continues to puzzle both experts and skeptics.
Timeline of Events: October 18, 1973
Crew on board the UH-1H Huey helicopter:
Captain Lawrence J. Coyne – Pilot in Command First Lieutenant Arrigo Jezzi – Co-Pilot Sergeant John Healey – Crew Chief Sergeant Robert Yanacsek – Flight Medic
The helicopter was flying from Port Columbus to Cleveland Hopkins Airport, cruising at 2,500 feet, when events took a mysterious turn.
The First Sighting
At 11:05 PM, Sergeant Yanacsek spotted a red light on the horizon. At first, it seemed like a distant aircraft, but it began approaching rapidly — closing the distance at an estimated speed of over 600 knots.
Evasive Action and Radio Failure
Captain Coyne initiated a descent to avoid a collision, dropping from 2,500 feet toward 1,700 feet. Attempts to contact Mansfield Airport failed — both UHF and VHF radios went dead.
Direct Confrontation
The approaching light slowed and stopped directly in front of the helicopter. The crew saw a metallic cigar-shaped craft approximately 60 feet long, with a dome and red and white lights at each end. Without warning, a brilliant green beam illuminated the cockpit.
Uncontrolled Ascent
The helicopter suddenly climbed at more than 1,000 feet per minute without pilot control, reaching 3,500 feet before the beam disappeared.
Civilian Witnesses Confirm the Event
Multiple witnesses on the ground in Mansfield reported seeing the same strange object. Some described the light as turning the night sky a vivid green. One family reported their yard was “lit up like daylight” during the encounter.
The UFO Departs
After several seconds, the green beam shut off. The UFO tilted upward, made a sharp 45-degree turn, and sped toward Lake Erie, disappearing from sight in seconds.
Official Recognition and Investigation
The case was investigated by:
The U.S. Army, The Federal Aviation Administration (FAA), Civilian UFO research organizations
It received national attention and won the National Enquirer Blue Ribbon Panel Award for “most scientifically valuable UFO report of 1973.”
Why the Coyne Incident Still Matters
The 1973 Mansfield UFO sighting stands out because:
Multiple trained military witnesses provided consistent testimony. Civilian eyewitness accounts matched the crew’s description. Electronic interference and unexplained flight behavior were documented. The UFO demonstrated controlled maneuvers beyond known aviation technology of the time.

The Substitute Teacher Who Wanted Blueprints of Our House
A fifth-grade assignment took a strange turn when a substitute teacher asked students to draw schematics of their homes. What followed — a wildly fictional floor plan and a priceless reaction from my mom — turned into one of my funniest childhood memories.
The Substitute Teacher Who Wanted Blueprints of Our House
Elementary school memories tend to blend together — cafeteria pizza, playground arguments, the eternal struggle of times tables — but every once in a while, something happens that sticks with you for life. For me, that moment came in the fifth grade during a week when our regular teacher was out, and we cycled through substitute teachers like we were testing models for durability.
By midweek, in walked a substitute with a mysterious, slightly intense energy — the kind of vibe that suggested he either meditated at dawn or worked a graveyard shift doing something he couldn’t talk about. We settled into our seats, expecting worksheets or quiet reading time.
But nope.
He had other plans.
“Today,” he announced, “we’re going to draw schematics of our houses.”
Schematics. Not drawings. Not little houses with smoke coming out of the chimney. Actual blueprint-style schematics. He wanted the layout of our bedrooms, our parents’ rooms, and where the pets slept. Every detail.
Now, to be fair, Highlights Magazine did have a feature that month teaching kids how to draw floor plans. So maybe he was just a bit overenthusiastic about cross-curricular learning. Or maybe — and this is my completely rhetorical adult theory — he worked the graveyard shift as a cat burglar gathering intel between heists. Just moonlighting between blueprints.
While the rest of the class tried their best to recreate their actual homes, my imagination sprinted in a totally different direction. The house I drew had:
- A massive master bedroom with an oversized bathroom for my parents
- Separate bedrooms for us kids on the opposite side of the house
- A kitchen placed right in the center like a command center
- And the dog — the true VIP — had a luxurious two-story doghouse
I had basically created a dream home designed by a 10-year-old watching too much Fantasy Homes by the Yard.
Later that day, my mom asked the usual question: “So, what did you guys do today?”
“We drew schematics of our house,” I said casually.
The look on her face was instant and intense. She wasn’t panicked, but there was definitely a “Why does a substitute teacher need to know the exact layout of my home?” expression happening. Parental instincts activated.
But then I showed her my diagram.
She stared at it. Blinked. Then sighed with massive relief.
“This isn’t our house,” she said.
“Nope! I made it up,” I replied proudly.
Her shoulders relaxed so much she probably lost five pounds of tension in one instant. If the substitute was secretly planning a heist, my masterpiece of misinformation would have sent him to the wrong house entirely.
Looking back, the whole moment feels like a sitcom setup — a mysterious substitute collecting “house schematics,” me creating a completely fictional piece of architecture, and my mom going on a full emotional journey in under 30 seconds.
Maybe he was just excited about the Highlights Magazine floor-plan activity. Or maybe — just maybe — he moonlighted in cat burglary. We’ll never know.
But if he was, I like to think I threw him completely off the scent.

Boom Supersonic Update 2026: Overture Progress, XB-1 Milestones, and What’s Next
Boom Supersonic’s 2026 update: XB-1 test success, Overture production timeline, funding progress, and the challenges facing the return of commercial supersonic travel.
By STM Daily News Staff
The race to bring back commercial supersonic travel is accelerating once again, led by Boom Supersonic, a Colorado-based aerospace company aiming to succeed where Concorde left off. As of 2026, the company has achieved meaningful technical milestones—but still faces significant financial, regulatory, and industrial hurdles.
Here’s a comprehensive look at where Boom stands today, and what it means for the future of high-speed air travel.
XB-1 Demonstrator Completes Historic Test Program
Boom’s experimental aircraft, the XB-1, has successfully completed its flight test campaign, marking a critical step toward validating the company’s supersonic technology.
- Achieved multiple supersonic flights in 2025
- Demonstrated aerodynamic stability and performance
- Tested “boomless cruise” capabilities to reduce sonic disturbances
The XB-1 program served as a scaled demonstrator for the company’s flagship commercial jet, proving that modern materials, software, and engine integration can support efficient supersonic flight.
With testing complete, the aircraft is expected to be preserved as a prototype, representing a turning point in private-sector aerospace innovation.
Overture: Boom’s Commercial Supersonic Jet
The centerpiece of Boom’s vision is the Overture, a next-generation supersonic passenger aircraft designed to carry between 60 and 80 passengers at speeds approaching Mach 1.7.
Current projected timeline:
- Prototype rollout: Targeted for 2026
- First flight: Expected around 2027
- Commercial service entry: Late 2020s (estimated 2029–2030)
Unlike Concorde, which catered primarily to elite travelers, Boom aims to position Overture with business-class pricing, potentially expanding access to faster global travel.
The aircraft is also being designed with sustainability in mind, including compatibility with sustainable aviation fuel (SAF).
Funding and Financial Momentum
In recent developments, Boom Supersonic secured an additional $100 million in funding, reinforcing investor confidence in the company’s long-term vision.
However, building a supersonic passenger aircraft remains one of the most capital-intensive challenges in aviation. Continued fundraising and strategic partnerships will be essential as the company moves from prototype to production.
Boomless Cruise: A Potential Game-Changer
One of Boom’s most significant innovations is its focus on “boomless cruise,” a method of flying supersonically without producing an audible sonic boom on the ground.
If proven viable at scale, this technology could influence regulatory changes—particularly in the United States, where overland supersonic flight is currently restricted.
The ability to fly faster-than-sound over land would unlock major domestic routes, dramatically reducing travel times between cities like New York and Los Angeles.
Manufacturing Challenges and Delays
Despite technical progress, Boom’s manufacturing ambitions face uncertainty. A planned production facility in North Carolina has experienced delays, raising questions about when large-scale assembly will begin.
Scaling production from prototype to commercial aircraft remains one of the most difficult phases of any aerospace program, requiring supply chain coordination, workforce development, and regulatory alignment.
Industry Skepticism Remains
While Boom has secured interest from major airlines, skepticism persists within the aviation industry.
Key concerns include:
- Certification complexity and regulatory approval timelines
- Operational costs versus ticket pricing
- Long-term demand for supersonic travel
Even airline executives have expressed cautious optimism, with some suggesting the project’s success remains uncertain.
The Bigger Picture: A Defining Decade for Supersonic Travel
Boom Supersonic has moved beyond concept and into real-world testing, demonstrating that modern supersonic flight is technically achievable.
However, the next phase—bringing Overture to market—will determine whether supersonic passenger travel becomes a viable industry once again or remains an ambitious experiment.
If successful, Boom could redefine global travel times. If not, it will join a long list of bold aerospace ventures that struggled to overcome economic reality.
