Two Events, One Night
The Phoenix Lights were not one event. They were two. Understanding this distinction is essential to understanding why the case remains unresolved, because the official explanation addresses one of them and not the other.
On the evening of March 13, 1997, tens of thousands of people across Arizona reported anomalous lights in the sky. Emergency dispatch centers throughout the state were overwhelmed with calls. The sightings spanned approximately 300 miles, from northern Arizona to the Mexican border, over the course of several hours.
But the witnesses were describing two different phenomena, separated by roughly an hour.
Event One: The V-Formation (approximately 7:55–8:40 PM)
Beginning around 7:55 PM, witnesses in Prescott, in northern Arizona, reported a large V-shaped or boomerang-shaped formation of lights moving slowly southward. The formation traveled across the state, passing over Phoenix and continuing toward Tucson and reportedly into Sonora, Mexico.
Many witnesses described the lights as maintaining an organized V or boomerang formation, while others reported changes in spacing and did not perceive a solid object. What made the first event extraordinary was not just the lights but what many witnesses described between them: something dark, enormous, and silent that blocked out the stars as it passed overhead. Estimates of its size ranged from several hundred feet to a mile wide. There was no engine noise. There was no sonic boom. It moved slowly and deliberately, as if it had nowhere to be and no reason to hurry.
This event has never been officially explained.
Event Two: The Stationary Lights (approximately 9:15–9:35 PM)
Roughly an hour later, a series of nine brilliant lights appeared in an arc formation near the Sierra Estrella mountains, southwest of Phoenix. These lights were stationary or slowly drifting. They were captured on multiple home videos and are the images most commonly associated with the "Phoenix Lights" in media coverage.
The United States Air Force later attributed these lights to LUU-2B/B illumination flares dropped by A-10 Warthog aircraft from the 104th Fighter Squadron of the Maryland Air National Guard during a training exercise at the Barry Goldwater Range. These flares ignite at altitude and drift slowly downward under parachutes, which is consistent with witnesses describing the lights as hovering before winking out one by one as they descended behind the mountain range.
This explanation is plausible and widely, though not universally, accepted for the second event.
It does not address the first.
The mile-wide, silent, V-shaped formation that crossed 300 miles of Arizona has never been officially explained.
The Witnesses
The Phoenix Lights case is unusual among UAP incidents because of the sheer number and variety of its witnesses. Dr. Lynne Kitei, a physician at the Arizona Heart Institute who became a key witness-researcher, estimated between 10,000 and 20,000 people witnessed the events that night.
Phoenix City Councilwoman and Vice Mayor Frances Emma Barwood compiled testimony from over 700 witnesses who contacted her office seeking an official investigation. She was the only elected official to publicly advocate for inquiry. She presented the witness accounts to the governor's office, which declined to investigate.
The witnesses included police officers, commercial pilots, military personnel, and families across the state. Their descriptions of the first event were remarkably consistent: a massive, silent, geometric formation that blocked out the stars.
The Pilot
Actor Kurt Russell, a licensed pilot, was flying his own aircraft toward Phoenix Sky Harbor International Airport that evening with his son Oliver aboard. His son asked what the lights were. Russell radioed the tower to report what he described as six lights over the airport, in absolute uniform, in a V shape. He was told nothing was showing on radar. Russell did not publicly discuss the sighting for years, and when he did, described it as a moment that simply did not fit any explanation he could construct as an experienced pilot.
The Governor
Arizona Governor Fife Symington III — a former United States Air Force captain and experienced pilot — held a press conference three months later, in June 1997. His chief of staff walked out dressed in an alien costume. The audience laughed. The message was clear: the governor was not taking the sightings seriously.
Ten years later, in March 2007, Symington reversed himself publicly. He said he had personally witnessed the craft that night. He described it as a massive delta-shaped craft that silently navigated over Squaw Peak, and called it enormous and inexplicable. He said he could not identify it as any known aircraft, and that as a former Air Force pilot, he was confident it was not conventional military technology.
Symington has said he remained silent in 1997 for two reasons: he was under federal indictment at the time and did not want to add controversy, and he did not want to cause public panic. The press conference with the alien costume, he later acknowledged, was an attempt to defuse public anxiety — not a reflection of what he had actually seen.
He saw the craft. He mocked the sightings. He stayed silent for ten years.
Then he told the truth.
The Official Explanation
The Air Force attributed the lights seen around 10 PM to military flares. The specific ordnance — LUU-2B/B illumination flares dropped from A-10 aircraft — is consistent with the behavior described for the second event: bright lights drifting slowly downward, appearing to hover, and disappearing behind the mountains as they descended.
Critics of the flare explanation note that military flares produce visible smoke trails as they fall, drift erratically with the wind, and do not maintain fixed geometric formations. However, at sufficient distance and under certain atmospheric conditions, these characteristics may not be visible to ground-level observers. The flare explanation for the second event remains contested but credible.
For the first event — the V-shaped formation that transited 300 miles of Arizona between 7:55 and 8:40 PM — no official explanation has ever been offered. The Air Force's flare attribution addressed only the later sighting. Retired Air Force pilot and astronomer James McGaha proposed that the first event was also caused by high-altitude A-10 aircraft flying in formation, but this explanation has not been adopted as an official finding.
One important counterpoint came from amateur astronomer Mitch Stanley, who viewed the early V-formation through a 10-inch Dobsonian telescope and reported in 1997 that he resolved the lights into separate aircraft. His observation was published contemporaneously, not decades later. Other witnesses, however, described a single enormous dark structure that blocked out stars as it passed overhead. Those descriptions remain difficult to reconcile with Stanley's account, and no formal investigation has determined which set of observations more accurately reflects what crossed the Arizona sky that night.
The Record
Dr. Lynne Kitei, who witnessed the event and spent years investigating it before coming forward publicly, documented the case in her book The Phoenix Lights: A Skeptic's Discovery That We Are Not Alone and in a companion documentary film. Kitei was a respected physician who had no prior involvement in UFO research. She described herself as a skeptic who was changed by what she saw and by the evidence she subsequently gathered.
Her investigation includes extensive image analysis, witness testimony, and attempts to recreate the military flare explanation. The documentary features interviews with witnesses, researchers, elected officials, and former astronaut Edgar Mitchell.

On the evening of March 13, 1997, two distinct aerial phenomena occurred over Arizona. The second — a series of stationary lights near the Sierra Estrella mountains — has been attributed by the Air Force to military flares, an explanation that is disputed but plausible.
The first — a massive, silent, V-shaped formation that crossed 300 miles of the state over approximately 45 minutes, observed by tens of thousands of witnesses including police officers, commercial pilots, air traffic controllers, a licensed pilot flying into Sky Harbor, and the sitting governor of Arizona — has never been officially explained.
The governor who mocked the sightings later admitted he saw the craft himself. The only elected official who publicly sought answers was met with silence. More than 700 witness statements were compiled. No investigation was conducted.
The Phoenix Lights remain the most extensively witnessed UAP event in modern history. They produced two phenomena, one explanation, and a governor's reversal that took a decade.
The flares have been explained. The formation has not.
Tens of thousands of people saw something cross the sky that night. Nearly thirty years later, nobody has told them what it was.
