Introduction
The military record surrounding the Phoenix Lights is more complete than it first appeared in 1997, but it is still not complete enough to map every reported sighting to a specific aircraft. Two points are now widely accepted. First, A-10 Thunderbolt II aircraft participating in the Air National Guard’s annual Operation Snowbird training were operating in Arizona that evening. Second, a later flare exercise over the Barry M. Goldwater Range provides a well-supported explanation for the stationary lights filmed south-west of Phoenix around 10 p.m. What remains less certain is whether the earlier reports of moving V-shaped lights across Arizona can be matched, flight by flight, to surviving military records. That distinction explains why the Phoenix Lights continue to be discussed as a multi-event mystery rather than a case that has been either completely solved or completely unexplained.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
What was confirmed about A-10 training that night
The strongest documented military evidence concerns Operation Snowbird, a recurring winter training programme based at Davis–Monthan Air Force Base near Tucson. During the 1997 exercise, visiting Air National Guard units flew A-10 Thunderbolt II aircraft across southern Arizona using established military training areas and transit routes.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Investigators who examined military records and later statements from Air Force personnel concluded that two different groups of A-10s were involved in separate activities that evening:
- One formation was returning from the Las Vegas area to Davis–Monthan during the earlier part of the evening.
- A different flight later conducted an illumination-flare exercise over the Barry M. Goldwater Range south-west of Phoenix before returning to base.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
This distinction matters because public discussion often merged both activities into a single explanation. The surviving military accounts instead describe two separate training events occurring within roughly two hours of each other.
Researchers including retired Air Force pilot James McGaha and Robert Sheaffer have argued that the earlier moving formation is consistent with A-10 aircraft flying in formation under visual flight rules (VFR). According to this interpretation, the aircraft were using steady formation lights rather than the more familiar anti-collision lighting, producing an unusual appearance at night.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Where the flare mission fits the timeline
The later event has the clearest documentary support.
Around 10 p.m., witnesses across the Phoenix metropolitan area observed a line of bright lights apparently suspended over the south-western horizon. Military officials later identified these as LUU-2 illumination flares released by A-10 aircraft from the Maryland Air National Guard during a training exercise on the Barry M. Goldwater Range. The lights appeared to extinguish one after another because the descending flares gradually disappeared behind the Sierra Estrella mountains from the perspective of observers in Phoenix.[projectunredacted.com]projectunredacted.comphoenix lights 1997Project UnredactedThe Phoenix Lights (1997) — UFO sighting Explained | Project Unredacted…
Several factors strengthen this explanation:
- The location matches the military training range.
- The timing corresponds with documented Operation Snowbird activity.
- The filmed behaviour—stationary appearance followed by sequential disappearance—is consistent with slowly descending illumination flares viewed from many kilometres away.
- Later confirmation from participants, including Maryland Air National Guard personnel, supported the official account.[Project Unredacted]projectunredacted.comphoenix lights 1997Project UnredactedThe Phoenix Lights (1997) — UFO sighting Explained | Project Unredacted…
For this reason, many investigators regard the flare explanation for the later Phoenix display as one of the strongest-supported aspects of the entire case.
Why the earlier flight record remains incomplete
The greater uncertainty concerns the earlier reports between roughly 8 p.m. and 9 p.m., when witnesses across a broad corridor from northern Arizona towards Tucson described moving formations or, in some cases, an apparently enormous V-shaped craft.
Although investigators have proposed that these observations correspond to five A-10 aircraft returning to Davis–Monthan, no publicly released package of military documentation reconstructs the complete mission minute by minute or correlates individual witness reports with aircraft positions.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Several factors contribute to this gap.
Military flights were not fully visible to civilian tracking
The proposed A-10 formation reportedly flew under visual flight rules rather than the controlled procedures typically associated with civilian airline traffic. Military formation flights also operate differently from civilian aircraft, including the use of formation lighting and, in some circumstances, reduced reliance on transponder returns that would later help reconstruct a flight path. As a result, modern-style digital tracking records simply do not exist for the 1997 event.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Public records are fragmentary
Unlike a modern accident investigation, there was never a comprehensive government reconstruction combining flight logs, radar data, cockpit records and witness timelines into a single official report. Much of today’s chronology has instead been assembled from interviews, later military statements, media investigations and independent researchers working years after the event.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Witness timing is difficult to reconcile precisely
Reports originated across hundreds of kilometres and were usually recorded after the event rather than in real time. Even where observers described similar formations, small differences in clocks, viewing direction and estimated duration make it difficult to determine whether everyone observed the same aircraft formation or multiple unrelated military and civilian flights.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
What the missing flight match does—and does not—mean
The absence of a publicly available aircraft-by-aircraft reconstruction should not be interpreted as evidence that military records contradict the conventional explanation. Instead, it reflects the limits of the surviving documentation.
The available evidence supports several conclusions with reasonable confidence:
- Military A-10 training activity occurred in Arizona on the evening of 13 March 1997.
- The later stationary lights are strongly supported by military records identifying an illumination-flare exercise.
- The earlier moving formation is plausibly consistent with A-10 aircraft returning from training, although no complete public reconstruction links every reported sighting to specific aircraft positions.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
Conversely, the available record does not establish that every early witness observed the same formation, nor does it conclusively demonstrate that every report can be explained by the documented A-10 transit. That remaining gap is one reason the Phoenix Lights continue to be discussed as a multi-event case: the military record convincingly explains part of the evening while leaving the precise correspondence between the earliest sightings and individual flights only partially reconstructed.[Skeptical Inquirer]skepticalinquirer.orgOpen source on skepticalinquirer.org.
