and 10:00 PM
Unexplained
The Phoenix Lights is the most widely witnessed UFO event in American history. On the evening of 13 March 1997, thousands of residents across Nevada and Arizona — including the sitting Governor of Arizona — observed one or more enormous formations of lights moving silently across the sky. Phone lines at local TV stations, police departments, and Luke Air Force Base were flooded with calls.
What makes the Phoenix Lights significant is not just the sheer number of witnesses, but their credibility. Pilots, doctors, police officers, teachers, military veterans, and ordinary families all reported the same thing: a vast, silent formation of amber lights, flying low and slow, blotting out the stars as it passed overhead. Many described feeling that whatever it was, it was immense — not a set of separate objects, but a single structure.
The official explanation — military flares dropped during a training exercise — addresses only the second of two distinct events that night. The first event, a V-shaped formation that tracked 300 miles from Nevada into Arizona, has never been officially explained.
Two Events, One Night
A critical and frequently overlooked detail about the Phoenix Lights is that there were two separate events on the same evening. Conflating them is the most common source of confusion about the case — and the official explanation that satisfied many journalists applied only to the second event, leaving the first largely unaddressed.
The V-Formation
A large, V-shaped or boomerang-shaped formation of lights was observed travelling from the Henderson, Nevada area south-east across Arizona, passing over Prescott, the Phoenix metropolitan area, and continuing toward Tucson and the Mexican border. Witnesses described it as slow-moving, silent, and enormous. Many reported it blocked out the stars as it passed overhead, suggesting a solid structure rather than individual craft.
The Stationary Lights
Approximately 90 minutes later, a separate string of bright, stationary amber lights appeared low on the horizon south-west of Phoenix. These remained visible for several minutes before fading one by one. The Arizona Air National Guard's 104th Fighter Squadron later confirmed they were dropping LUU-2B/B high-altitude illumination flares during a training exercise at the Barry M. Goldwater Range. This explanation is widely accepted for Event Two — but not Event One.
Event One: The V-Formation
The first event began around 8:15 PM and was reported along a 300-mile corridor stretching from Henderson, Nevada through Kingman, Prescott, and the Phoenix metropolitan area, then continuing south toward Tucson and into Sonora, Mexico. Witnesses along the entire route described broadly similar things: a formation of five to seven amber or white lights arranged in a V or boomerang shape, travelling at low altitude, in near-complete silence, at a relatively slow speed estimated by some witnesses at 30–60 mph.
What made this event particularly striking was the apparent size of the formation. Multiple witnesses in the Prescott Valley area — where the formation passed almost directly overhead — reported that the lights appeared to be attached to a single, solid craft with a roughly triangular outline. Ex-police officer and former Air Force officer Bill Greiner, a cement truck driver who watched the formation pass over Interstate 17, said it was "bigger than anything I've ever seen" and that it "blocked out the stars" as it went over. He was able to watch it for a considerable time as it moved slowly south.
"It was absolutely silent. I was outside and there was no sound at all. The lights were in a perfect V and they were moving slowly — much slower than any aircraft I've ever seen. And it was massive. When it got overhead it blocked out part of the sky."
— Bill Greiner, ex-police officer, Air Force veteran, watching from Interstate 17Dr Lynne Kitei, a physician who lived in the Phoenix Hills and had been observing and photographing unusual lights in the area for years before the mass sighting, photographed the formation and later dedicated much of her professional life to investigating the event. She described the lights as amber-orange, perfectly arranged, and behaving in ways that ruled out conventional aircraft. Her photographs and documentary film The Phoenix Lights (2005) became central to the public record of the case.
Event Two: The Stationary Lights
At approximately 10:00 PM — around 90 minutes after the V-formation had passed through — a second, visually very different event occurred. A row of bright amber lights appeared low on the horizon south-west of the Phoenix city centre, apparently stationary over the Estrella Mountains. These lights were filmed and photographed by numerous residents, and the footage is the most widely circulated imagery from the Phoenix Lights incident.
The Arizona Air National Guard's 104th Fighter Squadron later confirmed that A-10 Warthog aircraft were dropping LUU-2B/B illumination flares over the Barry M. Goldwater Range — a military training area located south of Phoenix — during that time window. The flares, which burn brightly for several minutes before extinguishing, would appear as stationary amber lights from Phoenix, apparently hanging over the mountains. This explanation is considered credible and is generally accepted for Event Two.
However, this flare explanation became — deliberately or otherwise — the official position on all Phoenix Lights sightings that evening. Critics and researchers quickly pointed out the problem: the flare drop occurred at 10:00 PM, but the V-formation had been reported by hundreds of witnesses across Nevada and Arizona nearly two hours earlier, at around 8:15 PM. The flares explain a photograph; they do not explain a mass sighting along a 300-mile track.
Witnesses
The Phoenix Lights was reported by an estimated several thousand individuals. Among them were multiple credible witnesses with professional backgrounds that make misidentification unlikely.
Governor Fife Symington III
Symington watched the lights from his home on the evening of March 13. At the time, he organised a press conference at which an aide appeared dressed as an alien — a move he later deeply regretted. In 2007, he publicly admitted he had seen the lights, that they were genuinely inexplicable, and that he wished he had handled it differently as Governor.
Dr Lynne Kitei
Had been photographing unusual lights over Phoenix prior to the mass sighting. On March 13 she photographed and filmed the event. She subsequently left her medical practice to investigate the case full-time and produced the 2005 documentary The Phoenix Lights. Regarded as the most prominent researcher of the incident.
Bill Greiner
Watched the V-formation from his cement truck while driving north on Interstate 17. His background as a police officer and Air Force veteran gives his account particular weight. He has stated that what he saw was unlike any military aircraft he encountered during his service.
Tim Ley & family
Tim Ley, his wife, son, and grandson watched the V-formation approach from the north and pass directly overhead for approximately 20 minutes. He described an enormous craft with five lights at its forward points. The family's extended observation time and the consistency of their account made it one of the most detailed on record.
Mitch Stanley
Observed the formation through a Dobsonian telescope. He reported seeing distinct individual aircraft in tight formation — separate objects, not a single craft. His account is often cited by sceptics but is disputed by researchers who note that he observed the lights briefly and may have been watching a different formation or time window.
Multiple law enforcement officers
Several on-duty law enforcement officers across the Phoenix metropolitan area and along the I-17 corridor reported the formation. Their reports were consistent with civilian witness accounts. None filed official UAP reports, citing concerns about professional credibility.
Governor Symington: The Admission
Of all the developments in the Phoenix Lights case, the most significant may be the eventual public admission by Governor Fife Symington that he personally witnessed the formation and believed it to be genuinely inexplicable.
On the day the story broke, Symington called a press conference — ostensibly to address the sightings. He had one of his aides walk into the room dressed in an alien costume, to widespread laughter. He later said this was a deliberate attempt to defuse public anxiety and avoid a panic, and that he regretted it deeply.
In 2007, ten years after the event, Symington gave an interview to CNN in which he stated clearly: "I saw a craft in the skies over Arizona that I'm a pilot and I know that no aircraft in the United States inventory from that period — and I'm pretty certain they don't exist today — could account for what we saw." He described it as large, structured, and moving silently. He said his joke press conference had been a mistake and that he had failed the thousands of Arizonans who deserved a serious response.
"As a pilot and a former Air Force officer, I can say with certainty that this craft did not resemble any man-made object I had ever seen. It was enormous and it was silent. I never thought I'd say this, but I believe it's not of this world."

The Flare Theory: What It Explains, and What It Doesn't
The Arizona Air National Guard confirmed that the 104th Fighter Squadron conducted a training exercise at the Barry M. Goldwater Range on the night of 13 March 1997, during which A-10 aircraft dropped LUU-2B/B illumination flares at approximately 10:00 PM. This is widely accepted as the explanation for Event Two — the stationary lights seen south-west of Phoenix around 10 PM.
The flare explanation does not, however, address Event One. The V-formation was reported at approximately 8:15 PM — nearly two hours before the flare drop — and was observed along a 300-mile corridor that stretches from Nevada to the Mexican border, not just over the Phoenix area. No military exercise has been identified that accounts for the 8:15 PM sightings. The Air Force has not commented on Event One beyond its statements about the flares.
Sceptics have argued that witnesses to Event One may have misidentified a formation of high-altitude military aircraft flying in close formation at night. This is possible, though it does not account for accounts of a single solid structure blocking stars, nor for the reported slow speed and extremely low altitude of the formation over Prescott. No formation of military aircraft operating over populated areas at low altitude and slow speed on that date has been acknowledged.
Night of 13 March 1997: A Timeline
PM
First Reports — Henderson, Nevada
A man in Henderson, Nevada reports a V-shaped object with six lights passing overhead heading south-east. The first in a chain of sightings that will stretch to Mexico.
PM
Prescott Valley — Overhead Pass
The Tim Ley family in Prescott Valley observe the formation approaching from the north. It passes directly overhead, blocking stars, for approximately 20 minutes. Multiple independent Prescott witnesses report the same formation.
PM
Phoenix Metro — Mass Sighting
The formation is visible across the Phoenix metro area — Scottsdale, Tempe, Chandler, Glendale. Thousands of residents see it. Phones at Luke Air Force Base, local police, and TV stations are flooded. Governor Symington observes from his home.
PM
Tucson and South Arizona
The formation continues south. Witnesses in Tucson and communities along the Mexican border corridor report lights consistent with the earlier sightings. Dr Kitei's photographs and video are captured in this window.
PM
Event Two — Flare Drop Over Barry Goldwater Range
Arizona Air National Guard A-10s drop LUU-2B/B illumination flares over the military training range south of Phoenix. Residents across the city see a row of stationary amber lights hanging low over the Estrella Mountains. This event is filmed by dozens and becomes the most widely circulated Phoenix Lights footage.
14
News Coverage Begins
Local TV stations in Phoenix begin reporting the sightings. The story rapidly goes national. Governor Symington's office holds a press conference — culminating in the alien costume stunt — that is widely criticised as dismissive.
1997
Air National Guard Confirmation
The 104th Fighter Squadron confirms it was dropping flares at 10:00 PM on March 13. This is adopted as the official explanation and widely reported as solving the entire Phoenix Lights mystery — despite applying only to Event Two.
Governor Symington Goes Public
Ten years after the event, Symington gives interviews confirming he personally witnessed the formation, believed it to be inexplicable, and that his press conference joke had been a serious mistake. His admission reignites international interest.
Second Phoenix Lights Event
A separate series of lights appears over Phoenix in April 2008, generating similar coverage. This event is quickly identified as road flares attached to helium balloons released as a publicity stunt — confirming that flares can explain some sightings, but do not retroactively explain the 1997 V-formation.
Why the Phoenix Lights Still Matter
The Phoenix Lights case occupies a unique position in UAP history. It is not a military encounter with a handful of witnesses, or a radar return with no visual corroboration. It is a mass civilian sighting, observed simultaneously by thousands of people across an enormous geographic area, with photographic and video evidence, and with a sitting state governor as a witness who later confirmed what he saw.
The official flare explanation, accepted uncritically by many outlets at the time, glossed over the two-event structure of the incident. By conflating Event One and Event Two, it implied that the entire evening had been explained — when in fact only the 10 PM stationary lights had an identified cause. The 8:15 PM V-formation — the larger, more widely reported, more dramatically described of the two events — remains without an official explanation nearly three decades later.
What also makes the case remarkable is the consistency of witness descriptions across a 300-mile corridor. People who had no contact with each other, in different cities, seeing the formation at different times as it moved south, described the same key features: a V or boomerang shape, amber or white lights, total silence, very low altitude, and an apparent size that struck most observers as far larger than any conventional aircraft. The consistency of independent accounts spanning Nevada, Arizona, and Mexico is difficult to explain away as mass misidentification.
"I don't know what we saw. But I know it wasn't flares. And I know it wasn't any aircraft in our inventory. What I do know is that thousands of Arizona residents saw the same thing, and they deserved better than a man in an alien costume."
— Governor Fife Symington, reflecting on his response to the 1997 sightingIn the intervening years, the Phoenix Lights has become one of the most studied UAP events in history. Dr Kitei's documentary, congressional interest prompted in part by Symington's admission, and the broader shift in US government attitude toward UAPs following the 2017 AATIP revelations have all brought renewed scrutiny. The case remains open — not in the tabloid sense, but in the straightforward sense that no authority has ever explained what thousands of people watched cross the Arizona sky on the night of 13 March 1997.
