APT-SAINT-CHRISTOL (84) 1980

During the night of 20–21 September 1980, numerous military witnesses repeatedly saw balls of light moving along varying paths, suddenly disappearing and reappearing. The sky was heavily overcast, and the weather was very stormy. That night, a motor race was taking place on the slopes of nearby Mont Ventoux. Although the investigation did not demonstrate a connection, reflections of car headlights in the night and on low clouds were considered a serious possibility. The topography of the racing course could explain the varied paths and successive appearances and disappearances.
