Mass sightings refer to events where a large group of people simultaneously observes an unusual object or phenomenon in the sky, often described as an unidentified flying object (UFO). These occurrences can attract significant media attention and public interest, leading to various interpretations and theories about the nature of the sighted object. Such sightings can happen in various locations and are sometimes linked to specific dates or events, like the Phoenix Lights incident in 1997. While some mass sightings are later explained as natural phenomena or man-made objects, others remain unexplained, fueling ongoing debates about extraterrestrial life and aerial phenomena.
