Zigzagging luminous trails sighted by a pilot in Châteauneuf-les-Martigues

Summary

On February 13, 1997, an experienced pilot in Châteauneuf-les-Martigues observed a yellowish trail moving slowly in the sky, which then accelerated in zigzag trajectories. A second trail joined the first and both advanced together. The investigation could not identify the phenomenon as an aircraft or a laser reflection. The witness, experienced with planes and helicopters, provided an observation that does not fit conventional explanations. The case remains unsolved.
