One of the most witnessed UFO events in history happened on October 13, 1917, in Fatima, Portugal, where approximately 50,000 people watched a UFO for 10 minutes. The object was large and round and so bright that it was mistaken for the sun. In the area of the city known as Cova de Iria, which is a rural area of the city, the object spun in the sky, mesmerizing viewers. The craft was reported to be silver with multicolored lights that were so bright they could be seen on the surrounding landscape in the daylight.
