On June 30, 1979, at approximately 11:30 PM, multiple motorists driving on a departmental road (route départementale) near Salon-de-Provence observed a luminous glow in the night sky. The object initially appeared as a stationary point of light before progressively moving and approaching the witnesses' position. As it drew closer, they observed two lights—one red and one green—positioned on either side of the central point, which alternately blinked in sequence. The witnesses, who became frightened during the encounter, reported hearing a whooshing or breathing sound ("bruit de souffle") as the object passed directly overhead.
During the overhead passage, the witnesses were able to discern a triangular shape to the object. Following this close approach, the craft rapidly departed toward the south and disappeared from view. The observation characteristics—including the sound profile, geometric configuration, and the specific color pattern of the lights—were deemed by GEIPAN investigators to be consistent with nighttime aircraft operations.
GEIPAN classified this case as "B" (probable identification), concluding that the witnesses most likely observed a conventional aircraft passing overhead. The red and green navigation lights, sound signature, and flight behavior all align with standard aviation characteristics, despite the witnesses' initial alarm and perception of anomalous activity.

04 Analyst Notes -- AI Processed
This case represents a textbook example of aircraft misidentification under nighttime conditions. The specific detail of red and green alternating lights is particularly significant—these are standard aviation navigation lights (port and starboard), with red on the left wing and green on the right as viewed from behind the aircraft. The triangular shape perceived by witnesses is consistent with the silhouette of an aircraft viewed from below, particularly when only the outline is visible against the night sky.
The "whooshing" sound described aligns with jet engine noise or propeller wash, and the witnesses' fear likely contributed to misperception of the event as anomalous. Salon-de-Provence is located in southern France near multiple air bases and commercial flight paths, including proximity to Marseille Provence Airport and the Salon-de-Provence Air Base (Base aérienne 701), home to the Patrouille de France aerobatic team. The southern departure direction mentioned in the report is consistent with standard flight corridors in the region. The GEIPAN investigation's conclusion appears well-founded based on the evidence presented.
05 Theory Comparison
BELIEVER ANALYSIS
Structured Craft with Unconventional Flight Characteristics
While navigation lights suggest conventional aircraft, a minority view might note that the witnesses described being 'frightened' and that the object 'rapidly departed'—potentially suggesting unusual flight characteristics. However, this interpretation lacks supporting evidence beyond subjective witness emotion, and rapid departure is within normal aircraft capabilities.
SKEPTIC ANALYSIS
Perceptual Amplification Due to Darkness
The nighttime setting and limited visual references contributed to the witnesses' misinterpretation of a routine aircraft as something anomalous. Fear responses and unfamiliarity with aircraft navigation light patterns amplified the perception of strangeness. The triangular shape, while accurately observed, is a common aircraft silhouette and does not indicate anything extraordinary.
06 Verdict
ANALYST VERDICT
This case is assessed as a probable aircraft misidentification with high confidence. The combination of red/green alternating navigation lights, audible engine noise, triangular profile, and proximity to known aviation corridors provides compelling evidence for a conventional explanation. While the witnesses' fear and the nighttime conditions may have amplified their perception of strangeness, all reported characteristics align with standard aircraft operations. GEIPAN's "B" classification (probable identification) is appropriate. This case holds minimal significance for UAP research but serves as a useful example of how conventional aircraft can appear anomalous to untrained observers under specific conditions, particularly at night when visual references are limited.
