Introduction

On the night of 13 March 1997, Arizona experienced one of the most widely reported aerial phenomena in U.S. history — later dubbed the Phoenix Lights. What made the event especially enduring in UFO lore were two distinct sightings: an early cluster or V‑shaped formation of lights moving across the state, and a later line of lights seen from Phoenix around 10 pm that became the most widely filmed and discussed images. For the 10 pm lights, the strongest and most documented explanation involves military illumination flares dropped over the Barry M. Goldwater Range, a major training area south‑west of Phoenix. This explanation is widely accepted among sceptical researchers and official sources, even if some witnesses still dispute it.

How the 10 pm Lights Appeared Over Phoenix

The lights that most people now associate with the Phoenix Lights phenomenon were reported around 10 pm MST by residents across the Phoenix metropolitan area. Witnesses described a row of bright, amber‑coloured points of light seemingly hovering in place in the sky before disappearing one by one. Because many of these lights were videotaped by amateurs, they became the iconic images linked to the incident.

Unlike the earlier “V‑formation” reports seen hours before, these later lights did not appear to move in the same way or follow a clear path through the sky. Instead, they seemed to hold position, linger for several minutes, and then simply fade or vanish — characteristics that puzzled observers at the time.

Why Flare Behaviour Matched the Videos

Within months of the event, Air Force sources and subsequent research pointed to a conventional and testable explanation: illumination flares dropped by A‑10 attack aircraft during a training exercise at the Barry M. Goldwater Range. These flares are designed to light up terrain at night and burn intensely while suspended from small parachutes, descending slowly through the air.

Several key pieces of evidence support this match:

  • Military confirmation: In later interviews, pilots from the Maryland Air National Guard confirmed that A‑10 aircraft were operating over the Barry M. Goldwater Range that evening and releasing LUU‑2B/B illumination flares as part of scheduled training activity. [Project Unredacted]projectunredacted.comphoenix lights 1997Project UnredactedThe Phoenix Lights (1997) — UFO sighting Explained | Project Unredacted…
  • Visual behaviour: The flares burn very brightly and descend slowly under parachute, appearing from a distance like fixed lights floating in the night sky. When seen from many miles away — such as from Phoenix toward the south‑west — the motion of the flares can be nearly imperceptible, creating the appearance of hovering or stationary lights.

  • Geometric effect of terrain: As the flares descended and drifted, the Sierra Estrella Mountains (south‑west of Phoenix) blocked portions of the view. From urban vantage points, each flare appeared to “wink out” as it dropped behind the ridgeline, reinforcing the impression of an orderly sequence of lights extinguishing one by one on cue. [Project Unredacted]projectunredacted.comphoenix lights 1997Project UnredactedThe Phoenix Lights (1997) — UFO sighting Explained | Project Unredacted…
  • Brightness and visibility: LUU‑2B/B illumination flares can burn with such intensity that they are visible from distances comparable to the roughly 50–70 miles from the Barry M. Goldwater Range to Phoenix. Skeptical investigations note that the luminosity and burn durations of these flares are consistent with what appears in the widely circulated video footage.

Taken together, these features — deployment timing, aerial behaviour, descent characteristics, and line‑of‑sight geometry — align closely with the recorded 10 pm lights that became the central images of the Phoenix Lights event.

Why the Military Explanation Arrived Too Late

Despite the strength of the military flare explanation for the 10 pm lights, it was not immediately communicated to the public following the March 1997 sightings, and the initial response from military authorities to press inquiries was ambiguous or lacking in detail. That delay helped fuel speculation and allowed various UFO narratives to gain traction before conventional explanations were widely reported.

Moreover, the flare explanation only addresses the later stationary lights — not the earlier reports of a large formation of lights over northern Arizona and Phoenix hours beforehand. Because the two sets of sightings happened on the same night and were later talked about as a single event, many witnesses did not differentiate between them, contributing to ongoing confusion about the role of flares. [Project Unredacted]projectunredacted.comphoenix lights 1997Project UnredactedThe Phoenix Lights (1997) — UFO sighting Explained | Project Unredacted…

In the years since, sceptical analysts and local journalists have pointed out that the delay in official explanation, combined with the dramatic, widely shared video images, cemented the 10 pm lights in public memory as something mysterious, even though the underlying cause is well understood within military and aviation contexts.

Summary: What This Means in Arizona’s UFO History

Within the broader Phoenix Lights episode, the Barry Goldwater Range flare explanation stands as the most compelling and well‑supported explanation for the later 10 pm lights seen over Phoenix on 13 March 1997. It is grounded in documented military training activity, consistent physical behaviour, and video analysis that matches known illumination flares.

That does not fully resolve all components of the Phoenix Lights — notably the earlier V‑shaped reports — but it does clarify a major strand of evidence that became central to why this event became so iconic. The gradual recognition of military flares as the source of the 10 pm lights has helped shift serious discussions about the incident toward evidence‑led interpretations and away from untested speculative narratives.
