In the early morning hours of May 2, 2010, at approximately 3:20 AM, a single witness in Favières, located in the Meurthe-et-Moselle department of the Lorraine region, observed two highly luminous spheres in rapid succession. The first sphere traveled rapidly toward the southeast before suddenly disappearing. Seconds later, a second luminous sphere appeared and executed a 180-degree downward loop before it too vanished abruptly.
The sighting occurred during the transition from Saturday night to Sunday morning, a timeframe commonly associated with social gatherings and celebrations. The observation lasted only a few seconds total, with both objects displaying similar characteristics: intense luminosity followed by sudden disappearance. The witness reported the incident to GEIPAN (Groupe d'études et d'informations sur les phénomènes aérospatiaux non identifiés), France's official UFO investigation agency operated by CNES (Centre National d'Études Spatiales).
Despite multiple follow-up attempts by GEIPAN investigators to obtain additional information from the witness, no supplementary details were provided that would have enabled a more thorough investigation. The case was officially classified as 'B' in GEIPAN's system, indicating a probable identification with a conventional explanation.

First Luminous Sphere Observed
Witness observes a highly luminous sphere traveling rapidly toward the southeast direction
03:20 + few seconds
First Sphere Vanishes
The first sphere disappears suddenly and completely, consistent with fuel exhaustion in an aerial lantern
03:20 + few seconds
Second Sphere Appears
A second luminous sphere appears shortly after the first disappears
03:20 + few seconds
Second Sphere Executes Loop
The second sphere performs a 180-degree downward loop before vanishing, suggesting wind influence or fuel depletion affecting flight stability

Investigation conclusion
Case Classified as 'B'
GEIPAN officially classifies the case as 'B' - probable observation of Thai lanterns, but unable to conduct thorough investigation due to lack of witness cooperation
03 Key Witnesses
Anonymous Witness 1
Civilian
low
Single witness in Favières who observed the event at 3:20 AM. Failed to provide additional information despite multiple follow-up requests from GEIPAN investigators.
"Not available - witness did not provide detailed testimony despite investigator follow-up attempts"
04 Analyst Notes -- AI Processed
This case presents several characteristics strongly consistent with Thai lanterns (lanternes thaïlandaises or Chinese lanterns). The sudden disappearance of both spheres aligns with the typical behavior of these aerial lanterns when their fuel source is exhausted - they extinguish abruptly rather than gradually fading. The timing of the sighting (3:20 AM on a Saturday night/Sunday morning) corresponds with the conclusion of parties and celebrations when such lanterns are frequently released. The 180-degree downward loop executed by the second sphere is consistent with the erratic flight patterns these lightweight objects exhibit when affected by air currents or as their fuel depletes.
The credibility assessment is limited by the sparse information available. The single-witness report, combined with the witness's failure to provide additional details despite GEIPAN's follow-up requests, reduces the evidentiary value of this case. No corroborating witnesses came forward, no photographic or video evidence was obtained, and the brief duration of the sighting (only seconds) suggests limited opportunity for detailed observation. The classification as 'B' by GEIPAN indicates the investigators' professional assessment that while the explanation is probable, absolute certainty cannot be achieved without additional evidence.
05 Theory Comparison
BELIEVER ANALYSIS
Unconventional Aerial Phenomena
The rapid southeast trajectory followed by sudden disappearance, combined with the second object's unusual 180-degree loop maneuver, could suggest controlled flight rather than drifting lanterns. The 3:20 AM timing is unusually late for celebration lanterns. However, this theory is significantly undermined by the lack of additional witnesses, the brief observation period, and the strong circumstantial evidence supporting the lantern explanation.
SKEPTIC ANALYSIS
Insufficient Data for Any Conclusion
While the lantern explanation is reasonable, the extreme brevity of the observation (only seconds), single witness testimony, and complete lack of follow-up information means we cannot rule out other prosaic explanations. These could include aircraft landing lights, drones with LED lighting, or even misidentification of celestial objects under unusual atmospheric conditions. The witness's failure to provide additional details despite investigator requests raises questions about the reliability of even the basic reported facts.
06 Verdict
ANALYST VERDICT
This case is almost certainly an observation of Thai/Chinese lanterns released during late-night festivities. The combination of factors - the Saturday night timing, the sudden disappearances consistent with fuel exhaustion, the luminous spherical appearance, and the erratic flight path of the second object - all point convincingly to this prosaic explanation. GEIPAN's 'B' classification is appropriate: the explanation is probable but cannot be definitively confirmed due to insufficient data. This case holds minimal significance for UAP research and serves primarily as a reminder of the importance of gathering comprehensive witness testimony and the challenges investigators face when witnesses do not provide follow-up information. The case demonstrates how conventional objects like celebration lanterns continue to generate UFO reports, particularly when observed under low-light conditions by unprepared witnesses.
