On Thursday, March 13, 1997, thousands of people across the Southwest United States reported seeing an unusual V-shaped formation gliding across the night sky. The initial report came from a man in Henderson, Nevada, who said the large formation was silhouetted by reddish-orange lights and was heading southeast. Soon after, callers in the Prescott area described a triangular assemblage of lights that obstructed their views of the stars, indicating a solid object. Later, reports from Phoenix indicated the unidentified flying object was making its way towards Phoenix Sky Harbor International Airport. The phenomenon came to be known as the Phoenix Lights.
