UFO identified as the International Space Station

Summary

On May 22, 2009, around 11:30 PM, two witnesses in Montaigu observed a bright white phenomenon moving steadily from west to east. One of them noticed the object making a zigzag before it quickly faded. After investigation, the GEIPAN experts concluded that the witnesses likely saw the International Space Station (ISS) as it entered Earth's shadow. The zigzag was not real but a perceptual illusion caused by the brain misinterpreting natural eye movements as changes in the object's path. This kind of phenomenon, known as autokinetic effect, is common in night observations of bright points.
