The Phoenix Lights
Two different events in one night, consistently conflated for thirty years
On the evening of 13 March 1997 Arizona residents first watched a V-shaped formation of lights transit the state, and about an hour later a stationary arc of bright lights over the city. Both episodes now travel under a single name.
Official position
The second episode, around 22:00, was identified as illumination flares dropped during a National Guard exercise on the Barry M. Goldwater range.
Alternative hypotheses
- The 22:00 episode: LUU-2 flares on parachutes — confirmed by exercise documentation and consistent with position, altitude and the sequence of extinction.
- The 21:00 episode: a formation of A-10 aircraft in transit — consistent with route and timing; observers saw only lights and closed a dark hull between them.
- The 21:00 episode as a single large object — with no radar confirmation.
The correction that matters most
“The Phoenix Lights” are two different events, an hour apart, of different character and different resolution status. Conflating them is the source of most of the confusion around the case.
The ~22:00 episode is explained. Illumination flares dropped during an exercise — with documentation, consistent geometry and the characteristic extinction sequence visible on the footage. That episode supplied most of the film material and most of the famous photographs.
The ~21:00 episode is far more interesting and far less documented. It is the source of accounts describing an enormous triangle occulting stars. Little footage exists, and what does exist shows points of light, not structure.
The decisive perceptual question
Did witnesses see lights joined by a single hull, or did they see a formation of lights and close a dark shape between them? The brain does this automatically and reliably. Without radar, or footage showing stars being occulted, it cannot be settled.
