The Phoenix Lights: Two Events, And The Explanation That Only Covers One

The downtown Phoenix skyline photographed at night from an elevated vantage point
Downtown Phoenix at night, photographed from the top of a condominium tower in September 2012, fifteen years after the sighting. The arena roof glowing violet at left, and several of the lit towers behind it, did not look like this in March 1997. This is the city the witnesses were standing in, not the sky they were looking at.

On the night of March 13, 1997, something crossed Arizona from the Nevada line down to Tucson, and thousands of people stood outside and watched it go. Then, at around 10:00 PM, a second and quite different thing appeared over the mountains southwest of Phoenix, and that one was recorded on video from Phoenix backyards. The military eventually explained the second one: illumination flares, dropped by A-10s of the Maryland Air National Guard over a bombing range. That explanation is good, it holds, and it has been used ever since to close a case it does not reach. Our research file refuses to let those two things be one thing, and neither will this dossier. Two events, tiered separately, including the sitting governor who told the state in 1997 that the mystery was solved and then, in 2007, said he had seen the craft himself.

CASE I_3_05 Reliability: The mass sighting and the military flare drop are documented (Tier 1); the earlier V formation still has no official explanation. 18 sources
Tier 1 · Verified Tier 2 · Credible Tier 3 · Speculative Tier 4 · Dubious

Phoenix is a real city with real mountains around it, and on the night of March 13, 1997 an extraordinary number of the people who live there went outside and looked up. Hold on to that before anything else. This is not a case built from one witness and a soft frame of video. It is a case built from a crowd, spread across most of a state, on a night in March.

And now the second thing to hold on to, which almost every retelling loses. There were two events that night, not one. One of the two has a confirmed and well-supported military explanation. The other has never received an official military explanation of any kind. Nearly every argument you have ever heard about the Phoenix Lights is really an argument in which the two speakers have different events in mind. This wing already carries the Roswell Incident, Rendlesham Forest, and the Nimitz Tic Tac. What makes this one different in kind is the crowd: not a handful of people at one location on one night, but a whole state looking up at the same time. Every claim below wears the tier our research file gives it, and every claim says which event it belongs to.

01Two Events, Not One

Tier 1 · Verified

Start with the scale, because it is the reason this case is not like the others. The Phoenix Lights event of March 13, 1997 is the largest mass UAP sighting in United States history by number of witnesses. Estimates run from several thousand people to over 10,000, along a corridor roughly 300 miles long, from Henderson, Nevada, through Prescott Valley, Phoenix, Scottsdale, and Tucson, Arizona.

Tier 1 · Verified

The people who have actually worked this case agree on the thing the public never hears. Investigators who have studied it in detail, among them Dr. Lynne Kitei, NUFORC director Peter Davenport, and journalist Leslie Kean, uniformly emphasize that media and public accounts conflated two separate events. That is not a fringe complaint about coverage. It is the analytical spine of the file, and it is the reason this dossier is structured the way it is.

Tier 1 · Verified

Event 1, roughly 7:30 to 8:45 PM. A V shaped or boomerang shaped formation of five to seven lights, or a single craft with lights along its leading edge, traversed Arizona from northwest to southeast. Witnesses in Henderson, Nevada, and in Paulden, Prescott Valley, Dewey, the northern reaches of Phoenix, and Tucson reported the formation at times consistent with a single object or formation moving south at roughly 30 to 50 mph. Over any given location, the passage took several minutes.

Tier 1 · Verified

Event 2, around 10:00 PM. A string of approximately nine bright orange amber lights appeared over the Estrella Mountains, the Sierra Estrella range, southwest of Phoenix. They stayed stationary relative to observers, then flickered and disappeared in sequence, left to right. Multiple home videos captured this one. The Maryland Air National Guard confirmed dropping LUU-2B/B illumination flares over the Barry Goldwater Range during training exercises that evening.

Tier 1 · Verified

Now the sentence this whole dossier is built around, and it is the file's own. The military's flare explanation, widely presented as resolving the entire Phoenix Lights case, applies specifically to Event 2. Event 1 has received no official military explanation. Not a disputed one, not a weak one. None.

The two events of March 13, 1997, side by side, exactly as the research file separates them. Tier 1 throughout. Read any headline about this case against this table and you can usually tell within a sentence which column the writer had in mind.

02Thousands Of People, And What They Said They Saw

Tier 1 · Verified

The witness count runs into the thousands, and it is documented in more than one place at once. NUFORC received hundreds of formal reports. The Arizona Republic newspaper received over 700 calls. Many thousands more people watched and never filed anything at all, which is the ordinary behavior of ordinary people who see something odd and decide not to make it their problem.

Tier 1 · Verified

The composition of that crowd is the part that is hard to wave off. The witness profiles are diverse: pilots, police officers, former military personnel, medical professionals, families, and casual observers. The file singles out two consistencies as notable. Descriptions of Event 1 agreed across independent witnesses separated by up to 200 miles, and those witnesses have not substantially altered their accounts across the decades since.

Tier 1 · Verified

Tim Ley, watching with his family of four in Phoenix, reported a vast V shaped craft passing directly overhead, blocking out stars as it went, which he described as at least a mile wide and completely silent.

Tier 1 · Verified

A truck driver on Interstate 17 north of Phoenix described a massive dark object with lights along its leading edge, moving slowly south, large enough to obscure a significant portion of the sky. The file does not name him, and neither will we.

Tier 1 · Verified

A former pilot in Prescott Valley, also unnamed in the file, noted two specific things rather than one impression. The lights held perfect formation with no relative motion between them, which is inconsistent with separate aircraft, and they were completely silent at what appeared to be low altitude, where engine noise should have been unmistakable.

That consistency is genuinely notable, and it is worth being precise about what it is evidence of. Independent people agreeing closely about the shape, the speed, and the silence of a thing in the sky is strong evidence that they were all looking at the same thing. It is not, by itself, a statement about what that thing was. Those are two different questions, and the file keeps them apart. So does this dossier.

03The Governor Who Changed His Mind

Tier 1 · Verified

On June 19, 1997, three months after the event, Governor Fife Symington III of Arizona held a press conference. His chief of staff was brought out in an alien costume, and Symington joked that the mystery had been solved. That press conference was widely treated as the official dismissal of the case.

Former Arizona Governor Fife Symington III speaking at a public event
Fife Symington III, photographed at an event in Scottsdale in June 2017, twenty years after the press conference. He was Governor of Arizona on the night of March 13, 1997, and by his own later account he was also one of the witnesses. This is a portrait from long afterward, not an image from the sighting or from the 1997 press conference.
Tier 1 · Verified

And he had seen it himself. Symington has since described a massive, delta shaped craft during Event 1, which he observed personally after being alerted by his security detail.

Tier 1 · Verified

In 2007 he said so publicly, on CNN's Larry King Live and to journalist Leslie Kean. His words: 'I'm a pilot and I know just about every machine that flies. It was bigger than anything I've ever seen. It remains a great mystery... I was expecting to see something that had a conventional explanation... as a pilot and former Air Force officer, I can definitively say that this craft did not resemble any man-made object I'd ever seen.'

It was bigger than anything I've ever seen. It remains a great mystery. Fife Symington III said that in 2007. In 1997 he was the sitting governor of Arizona, standing at a podium with his chief of staff in an alien costume beside him, telling the state the mystery had been solved. He has said since that the stunt was an attempt to diffuse the prior hysteria, and that he regretted it.
Tier 1 · Verified

The file carries his own account of the 1997 stunt rather than a theory about it, and so do we. Symington has said the press conference was an attempt to diffuse the prior hysteria, and that he later regretted it. That is his stated explanation, on the record, and this dossier does not go behind it to guess at anything else.

Tier 1 · Verified

The reason his reversal carries weight is not that a famous man said something. It is his particular resume. Symington is a former United States Air Force officer, a licensed pilot, and was a sitting state governor at the time he made the observation, which makes him one of the highest-ranking government officials ever to personally and publicly affirm a UAP sighting.

A fuller first-person account was located during this build rather than taken from the research file, and it is flagged as such. On his own website sits an article by Leslie Kean, published on the incident's tenth anniversary in 2007, in which Symington places his sighting at approximately 8:30 PM on March 13, 1997 and describes a large triangular craft moving slowly across the sky. He is quoted there saying 'It was enormous and inexplicable,' that 'it had a geometric outline, a constant shape,' and, drawing the exact distinction this dossier is organized around, that 'it couldn't have been flares because it was too symmetrical.' On the press conference, the same account quotes him: 'I wanted them to lighten up and calm down, so I introduced a little levity. But I never felt that the overall situation was a matter of ridicule.'

Two further quote variants from the 2007 interview turn up consistently across contemporaneous outlets. These were located during this build rather than taken from the research file, and they come with an honest caveat about how they were checked. He is quoted saying 'When I saw it, I said this is definitely a UFO. I have never seen anything like this in my life,' and describing the object as feeling otherworldly, adding that in your gut you could just tell it was otherworldly. CNN's own page for that November 9, 2007 piece could not be fetched directly during this build, so those two lines rest on independent corroboration from other outlets that quoted the same interview rather than on the original page. We would rather tell you that than let a quotation look better sourced than it is.

04What The Cameras Got, And What They Did Not

Tier 1 · Verified

Event 2 was captured on video by multiple Phoenix residents, among them Mike Krzyston and Terry Proctor. Those videos clearly show a line of bright lights above the Estrella Mountains extinguishing in sequence, which is consistent with the behavior of parachute-deployed illumination flares drifting down below a mountain ridgeline. Given the conflation the file describes, it is also the footage that carries the conflation the file describes, in which an explanation for this half is offered as though it settled the whole night.

Tier 1 · Verified

Event 1 has minimal video documentation, and the file gives two mundane reasons rather than a sinister one. This was 1997, before smartphones; consumer camcorders were the only option and most witnesses were not carrying one. And the thing itself was reportedly a dark shape against a night sky with bright lights on it, which is close to the worst possible subject for the cameras that did exist.

Tier 1 · Verified

One person had been filming the sky for years before any of this. Dr. Lynne Kitei, a Phoenix physician, had recorded anomalous lights from her home intermittently since 1995, and captured some footage on March 13, 1997. Her footage and documentation are presented in her book The Phoenix Lights: A Skeptic's Discovery That We Are Not Alone, published in 2004 by Hampton Roads Publishing, with later updated editions. The file's own text is ambiguous about which of the two events her March 13 footage belongs to, and we are not going to decide that for it.

Notice what that asymmetry does to the case, because it is the whole shape of the thing. The event that was recorded is the event that got explained. The event that was witnessed by thousands and recorded by almost nobody is the event that has never been explained at all. That is not a coincidence and it is not a conspiracy; it is what happens when the evidence available determines which question gets answered. But it does mean that the famous footage and the famous mystery are not the same night's work.

05The Flares, And Exactly What They Explain

Five A-10 Thunderbolt II aircraft of the 104th Fighter Squadron flying in echelon formation
Five A-10 Thunderbolt IIs in echelon formation, around 2008. The Maryland state flag on every tail fin and the MD tail codes mark them as Maryland Air National Guard, and the source file identifies the unit as the 104th Fighter Squadron: the same squadron and the same aircraft type named in the flare drop described here, photographed about eleven years afterward. A daylight training flight, not that night.
Tier 1 · Verified

The official position, issued through Luke Air Force Base public affairs, is specific enough to check. The lights were LUU-2B/B illumination flares, dropped by A-10 Warthog aircraft of the 104th Fighter Squadron, Maryland Air National Guard, during Operation Snowbird exercises at the Barry Goldwater Range, south-southwest of Phoenix. Named unit, named aircraft, named ordnance, named range.

Tier 1 · Verified

It did not arrive quickly. The confirmation of the flare drops took the military several months, which drew real criticism at the time about the delay, and which is one of the file's own open questions rather than a settled point.

A name was later attached to the mission, and this detail was verified during the build rather than drawn from the research file. In 2007, Lt. Col. Ed Jones of the Maryland Air National Guard publicly confirmed that he had personally flown one of the A-10s that dropped the illumination flares over the Barry Goldwater Range on the night of March 13, 1997. That moves the flare explanation from an institutional statement to a named pilot's on-record account of his own sortie, which is a meaningful upgrade in a subject where institutional statements are cheap.

Tier 1 · Verified

So here is the file's own verdict on the flares, in both directions at once. The flare explanation is well supported for Event 2: the timing, the location, the appearance, and the sequential disappearance pattern all match known flare behavior. And the flare deployment at around 10:00 PM does not account for Event 1, which happened roughly 7:30 to 8:45 PM, over a different geographic area, and involved a moving formation rather than stationary lights.

Tier 1 · Verified

For Event 1 there is no military explanation on the record at all. The paper trail that might have settled it is thin for reasons that are themselves part of the story: FOIA requests for radar data from Sky Harbor International Airport, Luke Air Force Base, and the FAA have produced limited results, either because the data was not retained from that period or because it was not requested in time.

Let us be unambiguous about where this dossier stands, because on this case a reader can reasonably expect either a debunk or a defense and this is neither. We are not disputing the flares. The flare identification for Event 2 is Tier 1 in our file, it matches the video, and a pilot has since put his own name to the mission. What we will not do is let a correct answer to one question be filed as the answer to a different question that nobody has answered.

06The Solid Object Argument

Tier 2 · Credible

Many Event 1 witnesses did not describe lights in formation. They described a solid object: a dark structured craft that blocked out background stars as it passed overhead. The Ley family's account is the most detailed of these, describing the craft passing between them and the star field and occluding stars along its surface as it moved.

Tier 2 · Credible

The inference the file draws from that, and marks as credible rather than verified, is straightforward. If those witnesses observed star occlusion accurately, then the lights were attached to a solid surface and were not separate aircraft flying in formation, which implies a craft of extraordinary size. Witness-geometry estimates range from several hundred feet to over a mile in wingspan.

The file then argues against itself, in its own Tier 2 section, and it does not grade the argument, so neither will we. The counter is that witness estimates of size and distance at night are notoriously unreliable. The human visual system cannot accurately gauge the size, altitude, or distance of lights in a dark sky without reference landmarks, and multiple aircraft in tight formation can appear as a single unified object to an observer on the ground. That is not a cheap objection. It is the standard limitation of night-sky eyewitness testimony, and it applies here as much as anywhere.

And then the file answers its own counter, which is the mark of a document trying to weigh rather than to win. The complete silence of the formation, at what appeared to be low altitude, is difficult to reconcile with any known conventional aircraft formation. Even gliders produce audible wind noise at the distances and speeds witnesses described. Notice that this exchange never resolves. Two serious arguments, neither knocked down, both carried at the same tier. That is what an honest unresolved case actually looks like from the inside.

07Before And After, And The Comet

Tier 2 · Credible

March 13 was not the first night or the last. Dr. Lynne Kitei documented amber and orange lights visible from the Phoenix area in 1995 and 1996, before the mass event. Similar formations have been reported intermittently in the Phoenix area since, in 2007, 2008, and 2012.

Tier 2 · Credible

Some of those later reports have been confirmed as ordinary: military flares again, and civilian skydivers carrying flares, including a team called SOS that performed nighttime flare drops in the area. That cuts both ways, and the file says so. It demonstrates that flare-like events genuinely do occur over this area, and it also demonstrates that credible witnesses have proved able to distinguish those known flare events from what they reported seeing during Event 1 in 1997.

Comet Hale-Bopp with its bright tail visible in a star field above a bare tree at twilight
Comet Hale-Bopp above a tree near Pazin, in Croatia, on March 29, 1997, sixteen days after the Phoenix sighting. The comet was a naked-eye object worldwide that month, which is part of why so many people were outdoors looking up. This photograph was not taken in Arizona, and the comet is not what anyone reported seeing over Phoenix.
Tier 2 · Credible

There is a reason so many people happened to be outdoors that month. Comet Hale-Bopp was at peak visibility in March 1997, one of the brightest comets of the 20th century, and many Arizonans were already outside watching it. The comet may simply have increased the number of people who were in a position to observe the Phoenix Lights at all.

Tier 2 · Credible

The same comet also poisoned the well. The Heaven's Gate mass suicide, thirteen days later on March 26, 1997, was connected to Hale-Bopp, and it created an immediate cultural association between unusual celestial phenomena and irrational belief. The file's reading is that this context likely shaped media framing of the Phoenix Lights, tying UFO sightings to cult behavior, and that it may have contributed to the dismissive official response and to Symington's initial mockery. That is the file's inference about a climate, offered as credible rather than verified, and it is not a claim about any individual's private reasoning.

08What Stays Speculative

Tier 3 · Speculative

The most popular non-alien explanation for Event 1 is a domestic one: that it was a classified United States military aircraft, perhaps related to reported black triangle programs, rumored successors to the B-2 Spirit, or experimental lighter-than-air platforms. It has been proposed for decades and it remains unverified.

Tier 3 · Speculative

The file hedges its own hypothesis in the same breath, which is the correct instinct. A silent, low-speed passage would be consistent with a lighter-than-air craft, a blimp or a hybrid airship. But the reported size and performance characteristics exceed any known program, and no classified program has ever been declassified that matches the descriptions. The explanation that fits the behavior does not fit the scale.

Tier 3 · Speculative

The full skeptical hypothesis sits at the same tier and deserves to be stated at its strongest. Event 1 was a formation of conventional aircraft, possibly military trainers out of Luke Air Force Base or Davis-Monthan Air Force Base, flying at high altitude and perceived as a single large object through the ordinary psychological tendency to connect separate lights into a unified shape. The absence of engine noise is explained by altitude.

The file states that hypothesis's weakness itself, rather than leaving it to a critic. It does not account for the star occlusion reports from multiple independent witnesses, and it does not account for a transit that took around two hours to cross a 300 mile corridor, which would require aircraft flying very slowly indeed. That two hour figure is the file's own, and we carry it as stated, but it sits oddly against the file's own 7:30 to 8:45 PM window for Event 1, which is about 75 minutes, and against its own 30 to 50 mph, which over 300 miles would take very much longer than either. The corridor, the window and the speed are each individually sourced and they do not reconcile with one another. That is worth knowing before anyone builds an argument on the arithmetic.

09The Skeptical Case At Its Strongest

The file carries a block of mainstream skeptical counterpoints that it deliberately does not grade 1 to 4. It presents them as serious positions rather than as claims to be tiered, so we will do the same, and we will present them properly rather than as a strawman set up to be knocked over.

Tony Ortega, then at the Phoenix New Times, produced the most detailed skeptical investigation of the case. His argument is that Event 1 witnesses were observing a high-altitude formation of conventional aircraft, and that the apparent scale of the whole event was amplified by media coverage and by social contagion. Astronomer James McGaha argued along a compatible line: that the Event 1 lights could have been high-altitude aircraft reflecting sunlight at post-sunset angles, or military aircraft in formation at altitudes where engine noise would simply be inaudible from the ground.

A specific operational version of that identification was located during this build, and it is recorded here at the file's own tier for the skeptical hypothesis, not raised above it. One thing to hold steady before reading it: the photograph earlier in this dossier shows the Maryland unit that flew the confirmed Event 2 flare mission, not the aircraft proposed here. The version some researchers offer is that five A-10 Thunderbolt IIs on Operation Snowbird, on the final night of a winter training deployment, were returning from Nellis Air Force Base in Nevada to Davis-Monthan Air Force Base in Tucson, flew down the Phoenix corridor, and landed at Davis-Monthan at approximately 8:45 PM. Observers using telescopes are reported to have resolved paired wing lights on each aircraft, and the chevron shape is said to suggest A-10s or T-37 trainers. McGaha has stated the position flatly: 'It was clearly aircraft in formation, flying at two different times and then dropping flares and it's clear to any rational person that's what it was.' Two things must travel with that. It is a different set of aircraft and a different claim from the confirmed Event 2 flare mission, and it carries the same weakness the file already names, since it does not explain the star occlusion reports or the complete silence of aircraft landing nearby. Symington and other Event 1 witnesses have publicly and specifically rejected this identification.

The sharpest skeptical point in the file is not about aircraft at all, and it is the one this dossier takes most seriously. Given the enormous volume of media coverage that followed Event 2, the videotaped flares, witnesses to Event 1 may have unconsciously absorbed details from Event 2 and from the subsequent public discussion into their own memories of what they saw earlier that evening. That is a genuine and well-documented concern in eyewitness science, not a rhetorical move. It also cuts at the exact thing that makes this case impressive, which is the consistency of the Event 1 accounts. A crowd that agrees may be a crowd that saw the same object, or a crowd that has been rehearsing the same story in public since 1997. The file does not claim to be able to separate those, and neither can we.

10The Two Claims The File Refuses

Two statements about this case are common enough that people repeat them in good faith, and the file marks both. Both, as it happens, are dismissals rather than extraordinary claims, which is itself worth noticing in a case of this kind.

Tier 4 · Dubious

First: that the entire Phoenix Lights event, both events, was military illumination flares. The file's own verdict on that is [PARTIAL, explains Event 2 only], and the evidence contradicts the wider version. The two events happened at different times, roughly 7:30 to 8:45 PM against around 10:00 PM. They happened in different parts of the sky. They had fundamentally different characteristics, a moving V formation against a stationary line. Conflating them gave media and officials a simple resolution that does not survive scrutiny. Read that carefully, because it is the one thing in this dossier easiest to get backwards: the flares are real and the flare explanation for Event 2 stands. What fails is the sentence that begins 'so the whole thing was flares.'

Tier 4 · Dubious

Second: that the Phoenix Lights was mass hysteria. The file marks this one [DEBUNKED], and the reason is definitional before it is evidential. Mass hysteria is a clinical term describing psychosomatic symptoms spreading through a group. That is not what happened here. Witnesses were calm. Many were sober observers who reported only what they saw and nothing more. Multiple independent witnesses across hundreds of miles described consistent details without any contact with one another. Whatever was in the sky, what happened on the ground was a mass observation, and calling it hysteria is not a skeptical position, it is a category error.

11What Would Actually Settle This

The file closes with five open questions, and the striking thing about them is that not one is a question about belief. Every one is a question about a record: whether a particular file was kept, and whether anybody has gone and looked at it. That is an unusually tractable list for a case of this fame.

The five research gaps the file names explicitly. These are its own open questions, not claims, and they are not tiered.
The Open QuestionWhat It Would Settle
Does FAA or military radar data from March 13, 1997 show anomalous returns along the Event 1 corridor?Whether anything with a radar cross-section actually flew that corridor, which is the single most decisive record that could still exist.
Why did the military take months to confirm the flare exercise?Whether the delay was ordinary bureaucratic lag or something that needs its own explanation. The delay itself is Tier 1 and documented; its cause is not.
Were any satellite assets or AWACS aircraft operating over Arizona that evening?Whether a second, independent sensor platform was in a position to have seen Event 1 at all.
Can the star occlusion observations be validated through reconstructions of that night's sky?Whether the solid-object argument, the central Tier 2 claim in the case, can be tested rather than only asserted.
Do civilian aviation radar records still exist from Sky Harbor or Prescott for the relevant window?Whether the FOIA results so far reflect records that were never kept, or records nobody asked for in time.

Fast Facts

The Night
March 13, 1997, over Arizona. The largest mass UAP sighting in United States history by number of witnesses: estimates from several thousand people to over 10,000, along a corridor roughly 300 miles long from Henderson, Nevada, through Prescott Valley, Phoenix, Scottsdale, and Tucson.
Event 1
Roughly 7:30 to 8:45 PM. A V shaped or boomerang shaped formation of five to seven lights, or a single craft with lights along its leading edge, moving northwest to southeast at roughly 30 to 50 mph, taking several minutes to pass any given location.
Event 2
Around 10:00 PM. Approximately nine bright orange amber lights over the Sierra Estrella southwest of Phoenix, stationary relative to observers, then flickering out in sequence from left to right.
The Reports
NUFORC received hundreds of formal reports and the Arizona Republic received over 700 calls. Witnesses included pilots, police officers, former military personnel, medical professionals, families, and casual observers, with descriptions of Event 1 agreeing across independent witnesses up to 200 miles apart.
The Governor
Fife Symington III held a June 19, 1997 press conference with his chief of staff in an alien costume and joked that the mystery was solved. In 2007 he said publicly that he had personally seen a massive delta shaped craft during Event 1. He is a former United States Air Force officer and a licensed pilot, and was a sitting governor at the time of the sighting.
The Video Record
Multiple home videos of Event 2, including footage by Mike Krzyston and Terry Proctor, showing a line of lights above the Estrella Mountains extinguishing in sequence. Minimal video of Event 1, consistent with 1997 camcorder technology and a dark shape against a night sky.
The Official Explanation
Issued through Luke Air Force Base public affairs: LUU-2B/B illumination flares dropped by A-10 Warthogs of the 104th Fighter Squadron, Maryland Air National Guard, during Operation Snowbird exercises at the Barry Goldwater Range. Confirmation took several months.
What It Does Not Cover
Event 1. The flare drop was around 10:00 PM, over a different area, and produced stationary lights rather than a moving formation. No military explanation for Event 1 has ever been offered.
The Records
FOIA requests for radar data from Sky Harbor International Airport, Luke Air Force Base, and the FAA have produced limited results, either because the data was not retained or because it was not requested in time.
The Refusals
That flares explain the whole night: the file marks it [PARTIAL, explains Event 2 only]. That it was mass hysteria: the file marks it [DEBUNKED].
The honest bottom line

So What Happened Over Arizona On March 13, 1997?

Tier 1 · Yes

A great deal here is simply documented. There were two events, not one. Event 1 ran roughly 7:30 to 8:45 PM as a V shaped or boomerang shaped formation of five to seven lights, or a single craft with lights along its leading edge, crossing from northwest to southeast at roughly 30 to 50 mph along a corridor from Henderson, Nevada, to Tucson. Event 2 was around 10:00 PM: approximately nine orange amber lights over the Sierra Estrella, stationary and then extinguishing in sequence, captured on multiple home videos, and confirmed by the Maryland Air National Guard as LUU-2B/B illumination flares dropped by A-10s of the 104th Fighter Squadron over the Barry Goldwater Range. Thousands of witnesses reported the night, NUFORC took hundreds of formal reports and the Arizona Republic over 700 calls, and the descriptions agreed across independent witnesses up to 200 miles apart. Governor Fife Symington III mocked the case in June 1997 and, in 2007, publicly said he had seen a massive delta shaped craft himself. And the flare explanation, which is correct for Event 2, does not reach Event 1, for which no official military explanation has ever been offered.

Tier 2 · Credible

One step down sits the argument that actually matters. Many Event 1 witnesses described a solid dark structured craft occluding background stars, and if those occlusion reports are accurate then the lights were attached to a surface rather than to separate aircraft, implying something between several hundred feet and over a mile across. The file's own counter is real: night-sky size and distance estimates are unreliable without reference landmarks, and tight formations can read as one object. The file's own counter to that counter is also real: the reported silence at apparently low altitude fits no known aircraft formation. Nothing in that exchange has been knocked down. Credible on both sides, unresolved. Also here: the pre-1997 and post-1997 Phoenix-area sightings, some of which have been confirmed as flares and skydivers, and the Hale-Bopp context that put so many Arizonans outdoors in the first place and then, through the Heaven's Gate suicides thirteen days later, tied the whole subject to cult behavior in the coverage that followed.

Tier 3 · Speculative

Three explanations for Event 1 stay speculative and stay here. That it was a classified American aircraft, a black triangle, a B-2 successor, or an experimental lighter-than-air platform: proposed for decades, never verified, and no declassified program matches the descriptions. That it was a lighter-than-air craft: fits the silence and the slow speed, fails on the reported size and performance. And the full conventional-formation hypothesis, aircraft at high altitude read as one shape by ordinary gestalt perception, which the file itself marks as failing to account for the star occlusion reports or for the transit time across the corridor, a figure whose internal tension we flag in the body rather than resolve. Serious, unconfirmed, none of them dismissed.

Tier 4 · No

Two claims are refused outright, and the file refuses them in its own brackets. That the whole night was flares is marked [PARTIAL, explains Event 2 only]: the two events had different times, different locations, and fundamentally different behavior, and conflating them produced a tidy resolution that does not survive scrutiny. Be precise about which half is refused, because this is the one people reverse: the flares are real, the flare explanation for Event 2 holds, and it is the word 'whole' that fails. And that any of it was mass hysteria is marked [DEBUNKED]: mass hysteria describes psychosomatic symptoms spreading through a group, and what happened here was calm, sober people hundreds of miles apart independently reporting consistent details without contact. That is a mass observation. These two are not open questions. The answer is no.

So where does that leave the Phoenix Lights? With a real date, a real corridor, and a real split down the middle of a single night. The second event is answered. Illumination flares over the Barry Goldwater Range, confirmed by the unit that dropped them, matching the behavior the videos actually show, and a pilot who has since put his own name to the sortie. The first event is not answered at all, and it is the one that thousands of people actually stood in their driveways and watched. What has never been produced for it is not a theory. It is a record: a radar return, a flight log, a photograph, anything at all from an instrument rather than a memory. And the file's own open questions are all of that same kind, every one of them answerable by somebody with the right archive and an afternoon. So which is the true state of those files: that there is nothing in them, or that nobody with the authority to open them has ever seriously gone looking?

Sources & further reading

Everything above is drawn from our research library on Theories of Anything, and every claim traces to the files below. The primary file is I_3_05, the Phoenix Lights, which carries the two-event separation as its own headline finding, the witness-scale figures, Symington's 1997 press conference and his 2007 reversal, the video record that exists for Event 2 and barely exists for Event 1, the Maryland Air National Guard flare confirmation together with the file's own statement that it does not reach Event 1, the Tier 2 solid-object argument with its counter-argument and counter-counter-argument attached, the Tier 3 hypotheses, the mainstream skeptical counterpoints it deliberately leaves ungraded, and the two Tier 4 refusals this dossier ends on. Four details were verified against primary and secondary sources during this build rather than taken from the file, and each is flagged where it appears: Symington's fuller first-person account published on his own site, the additional quote variants from the 2007 interview, Lt. Col. Ed Jones's confirmation that he flew one of the flare aircraft, and the specific flight-path version of the skeptical identification of Event 1. One note on citation hygiene, because it affects two entries in the file's own bibliography. Identifiers there did not survive checking during this build: two stated DOIs each resolve to a REVIEW of the book rather than to the book itself, one in a library review journal and one in Science, and a stated ISBN could not be matched to any edition. Every book named in this dossier is therefore cited by author, title, year, and publisher, with no identifier at all. An absent identifier is honest; a wrong one is a defect. Companion files go deeper on mass multi-witness sightings, on the psychology that separates a mass observation from mass hysteria, on official response patterns and delayed explanations, and on Symington's standing as a high-ranking government witness.
