The Phoenix Lights — Mass UFO Sighting Over Arizona — Paranormal History

What Were the Phoenix Lights?

The Phoenix Lights were a mass UFO sighting — the most witnessed UFO event in history — when thousands of people observed a massive V-shaped formation of lights fly silently across the Arizona sky on the evening of March 13, 1997. The event unfolded in two distinct phases over the course of nearly three hours, spanning a 300-mile corridor from the Nevada border to the edges of Tucson. Witnesses ranged from everyday citizens to airline pilots, military officers, and the sitting governor of Arizona. Despite official explanations involving military flares and aircraft formation lights, the sheer volume of credible testimony and video evidence has kept this event at the forefront of UFO research for nearly three decades. The Phoenix Lights remain one of the most compelling pieces of evidence that something extraordinary visited the skies above Arizona that night.

History

The Night of March 13, 1997

The evening began as any other spring night in Phoenix. Temperatures were mild, the sky was clear, and thousands of residents were going about their normal routines. At approximately 7:30 PM, witnesses in Henderson, Nevada — nearly 300 miles north of Phoenix — began reporting a formation of lights in the sky. Over the next two hours, the formation traveled southward through Arizona, passing over Prescott, Dewey, Wickenburg, and eventually the massive Phoenix metropolitan area before continuing toward Tucson.

The first phase of the event involved a V-shaped formation — later described by witnesses as a single, solid, triangular craft roughly a mile wide — that moved silently across the sky. The craft, if it was a single object, was enormous. Witnesses reported that it blotted out stars as it passed overhead and that individual lights were arranged in a Chevron pattern along its leading edge. The formation moved at a steady pace, roughly the speed of a commercial airliner, but made no audible engine noise.

By 8:30 PM, the formation had reached the Phoenix metropolitan area. Hundreds of people stopped their cars on highways. Families poured into backyards. The spectacle was visible across the entire valley. Many witnesses described the craft as having five or six large, amber-colored lights arranged in a V or boomerang shape. Some described it as a single, solid craft. Others described it as multiple aircraft flying in tight formation.

Phase Two: The Flare Incident

At approximately 10:00 PM — roughly two hours after the V-formation had passed — a second event occurred. A series of stationary lights appeared over the Squaw Peak area of Phoenix. These lights were bright, appeared to hover in place, and then gradually dropped toward the horizon one by one. This second event was captured on video by several residents, and it is this footage that is most commonly associated with the Phoenix Lights.

The Arizona National Guard later claimed that the second event was caused by LUU-2B illumination flares dropped by A-10 Warthog aircraft during a training exercise at the Barry Goldwater Range southwest of Phoenix. This explanation was widely accepted by media outlets and debunkers. However, many witnesses — including those who saw both events — insisted that the flares and the V-formation were entirely separate phenomena occurring on the same night.

Governor Symington’s Admission

The political fallout from the Phoenix Lights was immediate. Governor Fife Symington III — a former Air Force pilot — held a press conference in which he mocked the sighting. He brought his aide out wearing an alien head mask and joked that the “alien” had been apprehended. The press conference was widely covered and effectively dismissed the event in the eyes of many.

However, in 2007 — a decade after the sighting — Symington reversed his position in a remarkable interview. He admitted that he had personally witnessed the V-formation as it passed over the Squaw Peak area. He described the craft as “otherworldly” and said it was “enormous.” He expressed regret for his earlier mockery, stating that he had downplayed the event because he was afraid the public would panic. His admission was covered by major news outlets worldwide and lent significant credibility to the witness reports.

The Mystery

The Scale of the Sighting

What makes the Phoenix Lights so extraordinary is the sheer number of witnesses. Unlike most UFO reports — which come from one or two individuals — the Phoenix Lights were seen by thousands of people across a 300-mile corridor. Estimates of the total number of witnesses range from 10,000 to over 20,000, depending on the source. This makes it the most widely witnessed UFO event in recorded history.

Witnesses included experienced observers who were well-positioned to identify aerial phenomena. Major UFO researcher Dr. Lynn Kitei documented the event extensively and later produced a documentary, The Phoenix Lights (2005). Captain William L. Smith of the Arizona Air National Guard reported seeing the formation from Sky Harbor Airport. Multiple airline pilots who were off-duty at the time also reported the sighting, as did police officers on patrol.

The Two Events

One of the most debated aspects of the Phoenix Lights is whether the two phases — the V-formation and the flare drops — were related or entirely separate phenomena. Proponents of the flare explanation argue that the second event adequately explains the footage captured that night. However, many researchers and witnesses point out critical differences:

The V-formation moved across the entire sky from north to south, while the flares were stationary
The V-formation made no sound, while flares typically produce audible noise
The V-formation was visible for nearly two hours, while the flare event lasted roughly 30 minutes
Witnesses described the V-formation as a solid object, while the flares appeared as individual points of light

Dr. Kitei and others have argued that the two events were deliberately conflated by the military to provide a convenient explanation for the entire evening. This theory gained traction after the release of Air Force documents showing that the 161st Air Refueling Wing had indeed conducted flare exercises that night — but the timing and location of the exercises did not match the V-formation sighting.

The Missing Footage

Adding to the mystery is the fact that very little video footage of the V-formation itself exists. While hundreds of people witnessed the event, the early 1990s were before the era of smartphones, and most people did not carry video cameras. The few videos that do exist are grainy and have been the subject of extensive analysis. Some researchers have speculated that the military actively discouraged witnesses from sharing their footage, while others note that the simple reality of 1990s technology explains the scarcity.

Evidence and Investigations

The Kitei Investigation

Dr. Lynn Kitei, a Phoenix-based researcher and author, began investigating the event shortly after it occurred. Over the following years, she collected hundreds of witness testimonies, analyzed available video footage, and obtained government documents related to military activity in the area. Her work culminated in the 2005 documentary The Phoenix Lights, which featured interviews with dozens of witnesses and experts.

Kitei’s investigation revealed several key findings. Multiple witnesses described the V-formation as a single, solid craft — not a formation of separate aircraft. The craft was estimated to be between 1,000 and 1,500 feet wide based on witness accounts and the angle of observation. No conventional aircraft of that size existed in 1997, and the military has never acknowledged the deployment of any such craft over a major metropolitan area.

Radar Data and Military Records

Analysis of available radar data from the night of March 13, 1997, has been inconclusive. Some researchers claim that no radar returns corresponding to the V-formation were recorded, which is itself extraordinary given the reported size of the object. Others argue that radar data from that period is incomplete or was not preserved. The military’s explanation — that the V-formation was a formation of A-10 aircraft — has been disputed by aviation experts who note that A-10s do not typically fly in V-formation and that the described dimensions and behavior do not match known aircraft.

“I am a pilot. I know what aircraft look like. This was not an aircraft. It was the size of a football field, and it made no sound.” — Pilot, Phoenix, 1997

Expert Opinions

The Phoenix Lights have been analyzed by aerospace engineers, military analysts, and ufologists alike. Professor Paul Dean of the University of Melbourne, an expert in military aviation, has stated that no known military operation matches the description of the V-formation. Robert Powell, a physicist and UFO researcher, developed a geometric model of the sighting using multiple witness accounts and concluded that the object was approximately 1,600 feet wide and traveled at roughly 25 miles per hour.

Critics argue that the witnesses were mistaken — that they saw a formation of conventional aircraft and misjudged the distance, speed, and size. This explanation, known as the angular size illusion, is commonly cited in UFO debunking. However, many witnesses were experienced observers who had seen aircraft formations before and insisted that what they saw was fundamentally different.

What Do You Think?

The Phoenix Lights present a paradox: thousands of witnesses, video footage, the testimony of a governor, and no satisfactory explanation. The flare explanation accounts for the second phase of the event, but it does not address the V-formation that was seen by thousands of people over a two-hour period. The military has never fully explained what flew over Phoenix that night.

Some believe the event was a classified military exercise involving experimental aircraft. Others argue that the scale and behavior of the craft are inconsistent with any known technology — human or otherwise. Still others maintain that the witnesses were simply mistaken, overwhelmed by the spectacle of a training exercise they did not understand.

Whatever the truth, the Phoenix Lights left an indelible mark on UFO culture and on the city of Phoenix. The event is commemorated annually, and the debate it sparked continues to this day.

Summary

Thousands saw a V-shaped formation — over a mile wide — over Phoenix in 1997
