What are the "Phoenix Lights"?
The Phoenix Lights (sometimes called the "Lights over Phoenix") were a series of widely sighted unidentified flying objects observed in the skies over Arizona, Nevada, and Sonora Mexico on Thursday March 13th 1997.
Witnesses claim to have observed a huge carpenter's square-shaped UFO, containing five spherical lights or possibly light-emitting engines. Fife Symington (the governor at the time) was one witness to this incident; he later called the object "otherworldly."
The sightings were split into 2 events. The first event (the "V", which appeared over northern Arizona and gradually traveled south over nearly the entire length of the state, eventually passing south of Tucson) was the apparently "wedge-shaped" object reported by then-Governor Symington and many others. This event started at about 20:15 MST over the Prescott area, and was seen south of Tucson by about 20:45 MST.
The second event was the set of nine lights appearing to "hover" over the city of Phoenix at around 10 pm. The second event has been more thoroughly covered by the media, due in part to the numerous video images taken of the lights. This was also observed by numerous people who may have thought they were seeing the same lights as those reported earlier.
