Inside the Hudson Valley UFO Wave

North America’s most concentrated cluster of UFO reports that triggered the first-ever UFO convention in the region

Name	Hudson Valley UFO wave/flap
Occurred on	March 1983 to June 1986
Seen by	Approximately 5,000 residents
Investigated by	Philip J. Imbrogno and J.Allen Hynek

UFOs were a serious topic that the media pursued when they first gained attention in 1947. Stories about the phenomenon would receive plenty of coverage. This is also why a fraction of the public would initially be skeptical if any witness came forward.

But what if thousands witnessed the event? Would that still merit doubt?

At a time when people had grown doubtful of such stories and witnesses would first face mockery than acceptance, thousands claimed they saw what they believed could only be a UFO. This was the infamous Hudson Valley UFO wave. How did such a frenzy begin?

What Is the Hudson Valley UFO Wave?

The peaceful Hudson River Valley is home to executives and upscale residents—well-educated people nobody would expect to be swept up by the UFO fever. Yet, in the years between 1983 and 1986, exactly that happened to thousands of Hudson Valley residents.

The Hudson Valley UFO wave was a series of scattered sightings that spanned almost three years, during which residents reported seeing “immense, boomerang-shaped lights” moving through the sky. When urged to describe what they saw, the descriptions remained consistent, despite the thousands of witnesses coming from different counties.

Here’s a quick summary of everything that happened:

TIMELINE AND WITNESS DENSITY

• Incident Window. The incident occurred from 1982 to 1986, but witnesses continued to report activity sporadically until 1987.
• Peak Evening. Local police received the most reports, amounting to 300+, on March 24, 1983, across Westchester and adjoining counties.

KEY LOCATIONS

• Core Counties: Westchester, Dutchess, and Putnam, with spillovers into Fairfield County, Brewster, Yorktown, and Tarrytown.

How Did the Hudson Valley UFO Sightings Begin?

News about the incident was first released on March 23, 1983, by the local newspaper in Port Chester. The story hit headlines with multiple witness statements describing the triangular object. However, the initial burst of reports came on New Year’s Eve 1982 in Kent Cliffs.

The first-ever witness was an off-duty officer whose identity has remained anonymous since. He was reportedly with his family when they encountered the craft:

• It was boomerang-shaped with a solid structure.
• It had roughly 15 green, red, and white lights on its underside.
• It slowly moved and maintained an altitude of about 150 meters.

He added that, at one point, its colored lights went out and were replaced with three blinding white lights forming a triangle. These shone for five seconds before the colored ones returned, and the object drifted away.

How Many UFO Sightings Were Reported in the Hudson Valley?

Soon after, the same account would be repeated countless times, with families and even the police seeing something similar.

By March 23, 1983, the local police had already received over 100 calls regarding the same event. The numbers would only multiply in the coming years, with regional historical summaries estimating that there are 5,000+ witnesses in total.

Throughout the thousands, an impressively consistent description of the object was gathered:

• Witnesses described the object as a boomerang-shaped formation of lights, with some claiming it had a solid underside.
• The object moved slowly, occasionally hovering in some areas and doing 90° pivots.
• Witnesses estimated it to be football-field-sized, with some claiming it was larger at different angles.

What Were the Most Famous Hudson Valley UFO Incidents?

The Hudson Valley UFO wave was among the most documented sightings. Multiple witnesses came forward to report what they saw. Evidence gathered included:

• Three videos
• Four photographs

Among these was the Brewster recorded video from July 1984, in which a resident of the village managed to film the light formation.

This became a staple in UFO documentaries and is considered one of the most compelling pieces of evidence, and perhaps the most famous episode in the incident.

However, this wouldn’t be the only case, especially in the Hudson Valley UFO wave, where numerous statements were published, highlighting elaborate corroboration and the residents’ consistency and adamance in their claims. Here are some of their reports.

The March 17, 1983 Collection

Still in Brewster, a group of neighbors would observe a similar encounter on March 17, 1983. The unidentified object passed over their area at 8:40 PM, resulting in a shared experience and accounts that perfectly aligned; nobody would question their credibility.

It was Linda Nicoletti, a mother in her thirties, who first saw the object. She was looking out of her house’s window when she saw a V-shaped object with a row of bright, rainbow-colored lights hovering over Interstate 84.

As the object drifted closer to her home, Nicoletti noticed the absence of any engine noise, which only confirmed that it wasn’t an airplane. She watched it glide toward her neighbor’s house, staying motionless above him before heading north.

At the same time, a local government employee, Dennis Sant, was also just driving home from a church meeting with his children. Sant also reported seeing the object over Interstate 84 before it made a 360° turn and started approaching his house.

As Nicoletti shared, he claimed the object hovered 20ft above a telephone pole by his house. There, he saw the object clearly.

Its structure was very dark gray, metallic. It had numerous lights from end to end, red, green, and white. There seemed to be an amber light coming from it. This was in sequence, from one end of the shaft to the other. It seemed to be about the width of a football field and was dark, very gray metal. The lights were iridescent, bright. It stood in the sky, in its three dimensions. It looked just like a city that would hang in the sky.

Once the object was gone from their neighborhood, Nicoletti phoned the sheriff’s office, where the dispatcher shared that there had already been several calls about the same object.

The March 24, 1983 Encounter

Among the numerous witnesses who recounted their experiences was New Castle police officer Andi Sadoff. She was on a routine traffic patrol at 9 PM, parked on Cross Ridge Road, when she encountered the UFO.

I saw a string of white lights, very wide, forming a half circle. It was just coming over the ridge, and it caught my attention because it was so large. It approached my vehicle. I started shaking my head, thinking that this was strange because I heard no sound, and this thing was large. It then passed over my vehicle and headed towards town.

About four minutes later, it came back in my direction. The way the object moved was very smooth, as if it were gliding. When it came around, I could see the shape better. It was in the shape of a V with white lights on the top and green lights on the bottom.

On the same day, just 10 miles northwest of Sadoff’s location, another individual reported his own experience. Ed Burns was driving on the Taconic highway when it happened.

They came right over my car. I shut the radio off, rolled the window down, and looked out at this huge craft above me. I heard no noise. It was moving silently and slowly. It was triangular, chevron, ship, and the back of that chevron had to be as large as a football field.

As he continued driving down the highway, he claimed to have passed other cars parked along the road. Around a dozen people were also outside, looking at the object.

Then the craft seemed to stop. The different colored lights seemed to go off, and just the white lights seemed to stay on. It was hovering a bit. It was just there, looking like it was observing us as we were observing it.

Recently Shared Witness Statements

The above stories were accounts shared and published around the time of the Hudson Valley UFO wave. However, as the case grew bigger and more chaotic, other witnesses weren’t able to share their side of the experience until recently. In the Unsolved Mysteries article about the incident, anonymous commenters shared their personal accounts.

While we acknowledge how easy it can be to forge stories, we also want to cover as much of the incident as possible. We recognize the weight in everyone’s accounts, but still encourage you to take these with a grain of salt.

What Was the Truth Behind the Hudson Valley UFO Wave?

With an incident as massive as this, media and investigator attention were natural. However, despite this intrigue, a solid conclusion of what it was still hasn’t been achieved. Of the many researchers closely following the case, one of the most popular was Philip J. Imbrogno.

Philip J. Imbrogno’s Investigation

Imbrogno was still a budding UFO investigator when the Hudson Valley UFO wave happened. His role throughout the case was primarily to collect testimonies. He was assisted by J. Allen Hynek and his team of ufologists.

Together, they set up two phone lines to collect witness depositions and publish them in local papers. During the first 10 hours of the publication, they managed to gather more than 100 statements, and by March 24, 1983, they had already received over 300.

From what they’ve gathered, 85% of the sightings happened in Westchester and Putnam counties. Reports described the same V-shaped object, but how it was explained to have behaved varied:

• Lights jumping positions in the sky
• Lights disappearing and reappearing in place
• The object releasing self-propelled lighted objects
• Lights detaching from the formation and moving on their own.

These statements were later published in J. Allen Hynek’s last book before his death, titled Night Siege: The Hudson Valley UFO Sightings.

Poughkeepsie Journal Feature

Naturally, not everybody believed that the object was extraterrestrial. This prompted journalists to cover every possible explanation, and on June 28, 1984, they released a story with a different angle, one that steered away from UFOs.

Journalists claimed they spoke to witnesses who accused the pilots of flying small aircraft over the region in a V formation to trick the public. These witnesses claimed to have spoken to a police officer who followed the planes back to a local airport, where a pilot admitted to the hoax.

Anthony Capaldi, an air traffic control specialist, supported this explanation. He, like most residents, also saw the object and made the following conclusion.

The first time I observed the formation, it looked a little peculiar. From our vantage point in the tower, they just appeared to be one big light because they were flying in tight formation. I don’t think that if this formation flew over an individual’s head at a thousand feet, there’s any way you could mistake it for anything but the formation flying, due to the sound of the aircraft engines. I imagine that, at a thousand feet, you could really determine that it’s aircraft.³

The explanation was reasonable and was accepted to account for some of the incidents. However, many civilians still argued against it, saying it couldn’t have explained all the sightings during the Hudson Valley UFO wave.

In an interview, Westchester County lawyer and the founder of the Committee Against UFO Secrecy (CAUSE), Peter Gersten, said, “We’ve had three to five calls from Dutchess from people who said it was definitely planes. We know some pilots have intentionally or unintentionally been flying at night and confusing things.”

How Did the UFO Wave Affect the Hudson Valley Community?

The Hudson Valley UFO wave left a lasting impact on the region. The case’s volume of sightings generated a mix of excitement and unease. Residents had to cautiously scan the night skies for years in search of signs of the craft.

It also sparked a broader discussion about the phenomenon within the region. Not only did communities converse about their experiences, but the case also prompted an official UFO conference attended by over 1,500 people. This also included 75+ reporters like:

• New York Times
• ABC
• Chicago Tribune

As with every region affected by the UFO wave, the Hudson Valley area also embraced the phenomenon, incorporating it into its local culture. While the sightings eventually faded, they continued to honor their memory by opening restaurants and shops dedicated to the UFO phenomenon.

Are There Still UFO Sightings in the Hudson Valley Today?

Decades later, residents across multiple Hudson Valley counties continue to report unusual objects moving, hovering, or spinning in the night sky. These sightings still draw media attention and fuel ongoing speculation about the Hudson Valley’s reputation as a hotspot for UFO activity.

While the frequency of reports is far lower than during the original Hudson Valley UFO wave, the region remains highly sensitive to possible extraterrestrial encounters. Many locals continue to watch the skies closely, and this enduring interest has also drawn curious visitors to the area.

Contemporary UFO reports from the region are often compared with historical cases preserved in archived UFO documents.
