What Were the Phoenix Lights?
The Phoenix Lights, sometimes called the “Lights Over Phoenix,” were a series of sightings of unidentified flying objects over Arizona and Nevada on March 13, 1997. Lights of varying descriptions were seen between about 7:30 and 10:30 p.m. local time, across a stretch of roughly 300 miles, from the Nevada line, through Phoenix, to the edge of Tucson.
Two things make the case unusual. First, the number of observers: by common accounts, thousands of people saw something, and photographs and videos were taken. Second, the quality of some witnesses. Reports came from ordinary residents, a former police officer, an amateur astronomer, and later a state governor. UFO researcher and skeptic Robert Sheaffer has called it perhaps the most widely witnessed UFO event in history, even though he also argues it has a mundane explanation.
The key point for understanding the case is that investigators describe two distinct events, not one. A moving formation of lights crossed the state in the early evening. A separate set of stationary lights appeared over the Phoenix area later, near 10 p.m. Over the years the two have been blended in retellings, and that blending is a large part of why the story feels so puzzling.
What Did Witnesses Report That Night?
The early evening formation
According to the reports gathered afterward, the first sighting came at 7:55 p.m., when a witness in Henderson, Nevada, described a large V-shaped object travelling southeast. At about 8:15, a former police officer in Paulden, Arizona, reported a cluster of reddish-orange lights disappearing over the southern horizon. Soon after, lights were reported over Prescott Valley.
The best-known account comes from a family: Tim Ley, his wife Bobbi, his son Hal and his grandson Damien Turnidge. They said they first saw the lights from about 65 miles away as five separate lights in an arc, as if sitting atop a balloon. Then, they said, the lights seemed to approach. Over roughly ten minutes the spacing widened and the arrangement became an upside-down V. When it was a couple of miles away, the family said, they could make out a shape like a 60-degree carpenter’s square, with one light at the front and two along each side.
The family described the object as passing about 100 to 150 feet above them, moving so slowly and quietly that it seemed to hover, before it went through a gap in the mountains toward Piestewa Peak and the direction of Phoenix Sky Harbor International Airport. That is their account. Other witnesses, further along the route, described the same lights from much greater distances and in very different ways.
Actor Kurt Russell, an amateur pilot, reportedly told air traffic control he had seen the lights. Between 8:30 and 8:45, witnesses in Glendale saw the formation pass at an altitude high enough that thin clouds partly hid it.
The 10 p.m. lights over Phoenix
At about 10:00 p.m., a large number of people around Phoenix reported “a row of brilliant lights hovering in the sky, or slowly falling.” Many of the best-known photographs and videos come from this second event. In these images the lights sit in a line or arc, glow orange, and appear to hold their positions before dimming one by one.
What Is Documented and What Is Claimed?
The Phoenix Lights tend to blur fact and memory, so it helps to separate the layers.
| Layer | What it contains |
|---|---|
| Documented | Sightings on March 13, 1997, over Nevada and Arizona; photographs and videos of lights; Operation Snowbird flying out of Davis-Monthan Air Force Base; an Air Force explanation involving LUU-2B/B flares; later flare-related incidents in 2007 and 2008 |
| Witness claims | A single enormous craft shaped like a V or carpenter’s square; silent, slow passage a few hundred feet up; lights that did not behave like aircraft |
| Proposed explanations | A-10 aircraft in formation; slow-falling illumination flares; for some believers, an unknown craft |
| Still disputed | Whether the formation explanation fits what the closest witnesses say they saw, and whether one object or several were involved |
What Explains the Phoenix Lights?
The explanation most investigators accept ties both events to Operation Snowbird, a winter pilot training program run by the Air National Guard out of Davis-Monthan Air Force Base in Tucson. Sheaffer, who wrote up the case, argued that the incident consists of two unrelated events that share only one organizer. Tucson astronomer and retired Air Force pilot James McGaha says he investigated separately and also traced the sightings to A-10 Thunderbolt II aircraft.
Event one: a formation of A-10 jets
The first incident, often remembered as a “flying triangle,” began around 8:00 p.m. According to this explanation, five A-10 jets from Operation Snowbird were following an assigned air traffic corridor under visual flight rules. Civilian Federal Aviation Administration rules about blinking collision lights do not apply to military aircraft, so the jets displayed steady formation lights instead. Seen from a distance, steady lights in a fixed pattern can look like the lit points of one solid object.
The formation reportedly flew over Phoenix and on to Tucson, landing at Davis-Monthan at about 8:45 p.m. That timing fits the northwest-to-southeast progression of the reports.
One piece of supporting testimony comes from Mitch Stanley, an amateur astronomer in Scottsdale. He observed the high-altitude lights through a telescope and said they were quite clearly individual airplanes flying in formation.
Event two: the flare drop
The second incident began around 10:00 p.m. The U.S. Air Force explained it as a training exercise by four A-10 aircraft from the Maryland Air National Guard, also operating from Davis-Monthan. They dropped LUU-2B/B illumination flares, which burn for a long time and descend slowly, over the Barry M. Goldwater Air Force Range in western Pima County.
The flares would have been visible from Phoenix. The explanation says they seemed to hover because the heat of the burning flares produced a “balloon” effect on the parachutes, slowing their descent. The lights then appeared to wink out as they dropped behind the Sierra Estrella mountains southwest of the city. Investigators also note that the flares were so bright they could wash out the stars around them, which made the lights look like they were blocking the sky behind them.
A Maryland Air National Guard pilot, Lt. Col. Ed Jones, responded to a media query in March 2007 about the exercise, which is part of how the flare account became widely known. Some accounts say the military was slow to explain. The flare explanation was set out most fully years later, so the early timeline of official statements is less clear than the later one.
Why Do Some Witnesses Still Reject the Explanation?
The A-10 and flare account is detailed, but it has not persuaded everyone. The strongest objections come from people who say the shape and behavior they saw do not match jets.
- Silence and slowness. The Ley family described a nearly silent object passing at low altitude and low speed. A formation of A-10s would normally be heard at that height, and these jets do not hover.
- A solid shape. Several witnesses said they saw a dark structure connecting the lights, not separate points. Skeptics reply that the eye tends to fill in a shape between lights in a pattern, especially at night with no reference points.
- Merged memories. Because the two events are often combined, a witness may remember a close, silent craft that was really a distant formation, plus a separate memory of flares later.
- Distance and altitude. Without a reference, it is very hard to judge how far away or how large lights are in the dark sky. A bright light at high altitude can seem close and low.
Skeptics add that human perception of lights at night is unreliable in well-documented ways, especially for judging size, distance and speed. Believers answer that dismissing so many consistent accounts as misperception asks a great deal of coincidence. Both arguments are fair, and neither can be settled from memory alone.
What Did the Governor Say?
Fife Symington was governor of Arizona at the time. Years afterward he recounted seeing the lights himself and described the experience as “otherworldly.” That statement is often cited as evidence that something extraordinary happened. It is worth reading carefully: it describes an impression of what he saw, not a finding about what the lights were. A powerful public figure being impressed by lights in the sky is real testimony about the experience, but it does not identify the source.
Did the Phoenix Lights Happen Again?
Similar lights appeared in later years, and they offer a useful test of the explanation. In 2007, reports of lights over Phoenix were attributed to military flares dropped by fighter aircraft at Luke Air Force Base. In 2008, reports were traced to flares attached to helium balloons released by a civilian. In both cases, the lights drew the same kind of attention and the same sort of “hovering row” descriptions.
These later episodes do not prove what happened in 1997. They do show that flares, whether dropped or balloon-borne, can produce this exact kind of display and fool many observers. For skeptics, that is the strongest evidence that the 10 p.m. event was ordinary. For believers, it only covers one of the two events and leaves the early evening formation unaddressed.
What Remains Unexplained About the Phoenix Lights?
It is fair to say the second event, the row of lights near 10 p.m., is the better explained one. Flares match the timing, the appearance, the slow descent and the disappearance behind a mountain range, and the same kind of display has been repeated and identified since.
The first event is harder to close. The formation explanation fits timing, route and the telescope observation. But it relies on matching military flight records and recollections to hundreds of independent witness accounts made decades ago, and it must account for those who describe a silent object at low height. Where witnesses disagree with the explanation, there is no definitive recording that settles it.
So here is a plain summary of where things stand:
- The lights were real and widely seen.
- Photographs and videos exist, mostly of the later flare event.
- Two military training activities, a five-jet formation and a flare drop, are the accepted explanation for the two events.
- Some of the closest witnesses describe something that, to them, did not look or sound like jets.
- No physical evidence of an unknown craft has been presented.
Why Does the Story Endure?
The Phoenix Lights have lasted because they combine ingredients few cases do: a big city, thousands of onlookers, cameras, a public official, and an official explanation that arrived in pieces. The story also shows how hard it is to reconstruct a night of unfamiliar lights from memory. It fits neatly into the wider history covered in our UFO and UAP coverage, where the interplay between military activity and public perception comes up again and again. Some readers also find that suspicion toward official silence belongs with the questions we examine under conspiracy theories, since the case sits where reasonable doubt and speculation overlap.
The way perception can mislead, filling in shapes and distances that are not there, also connects to the material in consciousness, dreams and the mind. If you want more cases in the same spirit, browse every article in the journal or explore the unexplained by topic.

How to Weigh the Evidence Yourself
When you look at a case like this, a few habits help:
- Separate the two events. Ask whether a given account describes the early formation or the 10 p.m. lights.
- Check timing. The sequence of reports from Nevada to Tucson fits a moving formation. Reports clustered at 10 p.m. fit a stationary display.
- Treat estimates with caution. Size, height and distance judged by eye in the dark are the least reliable parts of any account.
- Respect the witnesses. Doubting a conclusion is not the same as calling someone a liar. Honest people can be wrong about what they saw and still be sincere.
The Phoenix Lights are best understood as a night when something real happened in the sky, was seen by a great many people, and was explained in ways that satisfy some and leave others unconvinced. That tension, more than any single light, is the lasting mystery.
Questions and answers
Did they ever find out what the Phoenix Lights were?
According to the U.S. Air Force and independent investigators, yes. They traced two separate events to military aircraft: a formation of A-10 jets crossing the state, and flares dropped over a training range later that night. Some witnesses reject the explanation, so the debate has not fully ended.
What was the cause of the Phoenix Lights?
The accepted explanation points to Operation Snowbird, a winter pilot training program run out of Davis-Monthan Air Force Base in Tucson. A-10 aircraft flying in formation explain the early evening lights, and LUU-2B/B illumination flares dropped on the Barry Goldwater Range explain the later row of lights.
How many people witnessed the Phoenix Lights?
No exact count exists. Reports describe thousands of people across roughly 300 miles, from the Nevada line to the edge of Tucson, between about 7:30 and 10:30 p.m. Many accounts came from people who never filed a formal report, so any precise number would be a guess.
Are the Phoenix tapes 97 real?
Photographs and videos from that night do exist, and they show real lights. The dispute is over what the lights were, not whether they were filmed. Footage of the later row of lights matches the behavior of slow-falling flares, according to investigators, while some believers read the same images differently.
Was there more than one Phoenix Lights event?
Yes. Investigators describe two distinct events on March 13, 1997: a formation of lights that travelled across the state in the early evening, and a stationary row of lights seen over Phoenix around 10 p.m. Witnesses often blend them into one story, which is part of why the case confuses people.
