The Phoenix Lights were two distinct military events, yet they became a cultural phenomenon.
In short: On March 13, 1997, thousands of Arizonans witnessed mysterious lights across the sky. While many perceived a single, massive craft, investigators later identified two separate military training exercises. The incident remains a touchstone for UFO enthusiasts, despite clear evidence linking the sightings to Air National Guard operations.
The Phoenix Lights incident occurred on March 13, 1997, spanning roughly 300 miles from the Nevada border to Tucson, Arizona. Witnesses reported two distinct phenomena: a triangular formation of lights passing overhead in the evening and a series of stationary, glowing lights appearing later that night. The first event, observed around 8:00 p.m., involved five A-10 Thunderbolt II aircraft from the Maryland Air National Guard. These jets were participating in Operation Snowbird, a winter pilot training program based at Davis-Monthan Air Force Base. Because they were flying under visual flight rules, the aircraft displayed steady formation lights rather than the blinking collision lights required for civilian craft.
The second event, which began around 10:00 p.m., consisted of a row of brilliant lights that appeared to hover or slowly descend. This was identified as a flare-drop exercise conducted by a different flight of A-10 aircraft at the Barry M. Goldwater Range. The military utilized long-burning LUU-2B/B illumination flares attached to parachutes. Rising heat from the burning flares created a balloon effect, slowing their descent and causing them to appear stationary. As the flares fell behind the Sierra Estrella mountains, they vanished from view, creating the illusion of lights winking out one by one. Luminosity analysis confirmed that these flares would be clearly visible from Phoenix at a range of 50 to 70 miles.
Despite these explanations, the event achieved legendary status, fueled by the accounts of high-profile figures like former Arizona Governor Fife Symington. Although Symington initially mocked the reports with an alien-costumed aide, he later claimed to have witnessed an otherworldly craft himself. Skeptics have proposed alternative hypotheses, including experimental lighter-than-air craft, but no concrete evidence has emerged to support these theories. The incident has since inspired numerous films, documentaries, and books, cementing its place in popular culture as a quintessential mystery of the late 20th century, even as military records and expert analysis point to routine training maneuvers.
