UFO in Marseille 1981 solved as advertising balloon

Summary

On November 1, 1981, several witnesses in Marseille observed a gray, cylindrical object moving silently toward the sea. The object, about 4 meters long, generated curiosity due to its appearance and lack of noise. After a detailed investigation, it was discovered to be an advertising balloon launched by children from the terrace of the "Le Corbusier" building, located about 300 meters from the observation site. This case is a classic example of how everyday objects can be misinterpreted as unexplained phenomena, especially when viewed from unusual angles or under specific lighting conditions.
