Ammerschwihr 2015, Observation of red lights in triangle

Summary

On July 15, 2015, a witness in Ammerschwihr (France) observed three very bright red lights forming a triangle and flying at low altitude. The lights emerged from a forest, headed toward the witness's building, turned 45 degrees, and disappeared. The case was classified as "B" by the GEIPAN, indicating a likely explanation. Investigators noted factors such as the match with the color and behavior of paper lanterns, their collective movement, and the short duration of the observation. Additionally, nearby facilities suitable for launching such lights were mentioned, though not visible from the witness's location.
