Thousands of residents witnessed a V-shaped formation of lights and a large object crossing the night sky across Arizona. Authorities explained part of the phenomenon as military flares.
On the night of March 13, 1997, many Arizona residents reported a V-shaped formation of lights and a large, silent, slow-moving object in the sky. Sightings spanned the entire state and lasted for hours. The military later said some of the lights were flares dropped during training. But many witnesses insisted they saw a single solid structured craft rather than scattered lights. With its large number of witnesses and abundant footage, it became a defining case of mass sightings.
